This function saves a figure or single axes to one or more vector and/or bitmap file formats, and/or outputs a rasterized version to the workspace, with the following properties:
- Figure/axes reproduced as it appears on screen
- Cropped/padded borders (optional)
- Embedded fonts (pdf only)
- Improved line and grid line styles
- Anti-aliased graphics (bitmap formats)
- Render images at native resolution (optional for bitmap formats)
- Transparent background supported (pdf, eps, png)
- Semi-transparent patch objects supported (png only)
- RGB, CMYK or grayscale output (CMYK only with pdf, eps, tiff)
- Variable image compression, including lossless (pdf, eps, jpg)
- Optionally append to file (pdf, tiff)
- Vector formats: pdf, eps
- Bitmap formats: png, tiff, jpg, bmp, export to workspace

This function is especially suited to exporting figures for use in publications and presentations, because of the high quality and portability of media produced.

Note that the background color and figure dimensions are reproduced (the latter approximately, and ignoring cropping & magnification) in the output file. For transparent background (and semi-transparent patch objects), use the -transparent option, and set the axes 'Color' property to 'none' where desired. Pdf, eps and png are the only file formats to support a transparent background, while the png format alone supports transparency of patch objects.

When exporting to vector format (pdf & eps), and to bitmap using the painters renderer, this function requires that ghostscript is installed on your system. You can download this from:
http://www.ghostscript.com

When exporting to eps it additionally requires pdftops, from the Xpdf suite of functions. You can download this from:
http://www.foolabs.com/xpdf

Usage examples and tips can be found in the README section at:
https://github.com/altmany/export_fig/blob/master/README.md

This is the best solution I've found for creating high-quality PDFs. It's a lifesaver when I want to include graphics from MATLAB in a LaTeX document.

Hi,
I am plotting a grid of pixels in matlab and I have to overlay multiple grids on same figure using hold on (around 100). At the end figure become extremely heavy that if i zoom in a little portion of figure, it take computer to process an hour to zoom.
I was thinking to export figure on EPS format and then see the zoomed figure in EPS viewer. However, i am not able to see zoomed information of figure. Please let me know is it possible to preserve original figure information in EPS format so that when i zoom in EPS figure, I can see details just like in MATLAB?

Really useful function, thank you! However, there is a small bug that occurs when using the LineWidth option in conjunction with anti-aliasing:

figure(1), clf;
z = linspace(0,4*pi,250);
x = 2*cos(z) + rand(1,250);
y = 2*sin(z) + rand(1,250);
scatter3(x,y,z,'Marker', 'x', 'LineWidth', 4);
export_fig -a4

The saved figure will display points at default line width rather than the specified value.

Hello everyone, I used this function to export my figures to PDF. Then I used those pdf figures in my latex paper. When I uploaded the paper, I got "fonts not embedded" error. Is not this function supposed to embed the fonts already? What else should I do to not to get this error?

Joris Meurs

*.EMF would be great

Neil Arthur

In order to export to the desired size, using:
set(gcf,'Position',figurePosition)
or
set(gcf,'PaperPosition',paperPosition)
does not work on its own. You also need to change the LooseInset property with
set(gca,'LooseInset',get(gca,'TightInset'))
Then use export_fig with no padding. Then the figure will print exactly to the desired size...Is this correct? Or am I missing something?

Leo Simon

Sorry, I downloaded the latest option and the issue I noted earlier has been fixed.

Leo Simon

It's a great addition, but there's one issue, which is that the padding option works only if options is a vector, which it isn't in my case. I hacked my code: on line 349 of export_fig, the third argument is hard-coded as a 1, if you change it to be options.bb_padding, then one can use the -p option generally. Hopefully this doesn't create other problems, but it seems to be working for me.

I have enjoyed using this package for many years. Of recent I've started to use the Parallel Computing Toolbox (PCT). Are there any plans on getting export_fig to work with the PCT? PCT in parfor loops use the -nodesktop and -nofigure options which export_fig doesn't seem well set up to handle.

one of the best toolbox. Thank you very much.

Very useful. The figure quality is very good

elvin feng

Good stuff here.

But I'm having an issue, when exporting to a tif and trying out the different options (-native, -q, etc) the output comes out the same resolution but the quality is diminished. 4x4 regions appear to be averaged into one which is quite the loss. Am I using the wrong options here to export or is this intended?

This function has made my life a great deal better for the last 7 years. Thanks a lot to the developer/maintainer!

BUT: after the sudden death of my previous PC and subsequent complete system reinstallation, pdf figures exported with export_fig now come in Courier font. Makes for fancy retro hipster style graphics but is unfortunately not an option for any kind of publications, and no solution found locally so far - I had to go back to Matlab's built in print function ):

Has anyone experienced similar behaviour? Is the problem on Matlab's or Ghostscript's side, or somewhere else?

Some clues:
- The Font tab in the pdf's Document Properties states: "any (Embedded Subset)" - somewhere in the exporting process the figure's font (Helvetica, I believe) goes missing.

- current system specs: Windows 7, Matlab 2016b, Ghostscript 9.19

- Browsing through older pdf files, I found that any pre-reinstall combinations of various Matlab and Ghostscript versions up to R2015b / 9.15 worked. There, the pdf specifies "Helvetica" as its embedded font (and thus it also displays Helvetica/Arial).

Oliver Karger

Hi, this export package is great, the plot quality is so much better than with the built-in Matlab functions.

What I am wondering is in the pdf export, that the grid, which constists of faint grey lines in the Matlab figure becomes a dashed white line in the pdf export. Since I am using dashed lines to separate visually certain regions in the plot the now white dashed lines are overlapping with my annotation lines.

In the png export output the gridlines are still in a faint grey color.

Where can I change that to get the same result for the pdf export as well?

Thanks and best,
Oliver

Hello Yair,

Excellent contribution.. But i'm struggling with '-append' option because I want to put two gui figures in the same file and with your function I'm able to do that, but I loose some of the handles of my figures (e.g. uitables, string boxes..). Any ideas what could this be?

Thank you very much for this. If I was choleric, you would have prevented me from beating up my computer because of the annoying and shitty handling of the print function. Unsuccessfully tried for over an hour to get rid of the outer padding of saved plots. With your script, it was about 8 minutes, including download time.

I work on a computer where I don't have administrator rights. So, I can't install ghostscript. Is there any work around for that? (on Windows 7 - 64bit)

Very good program. However, I experience an issue when trying to export images with semi-transparent plotted points (using MarkerHandle.EdgecolorData and MarkerHandle.FacecolorData). The image that is exported does not show my points as semi-translucent, as they are in the plot. Instead, they show up as opaque.

@Miles, you can try out the following code to specify file name.

export_fig (sprintf('figure%d',mm));

I used it in a loop eg. for mm=1:5

I am having trouble specifying the filename when using this function...my code looks something like this:

...[code to make my figure]...

temp_str = strjoin({'filepath\',filename},'');
export_fig({temp_str})

When I do this, I still get a file saved in my directory which is named "export_fig_out.png". I was expecting that I would get a file with my "filename" that I specified.

Can anyone explain what I am doing wrong? I am slightly confused about the syntax for this function, I think.

Thanks!

Yue Chen

Great function. Thanks for sharing.

I have a question concerning crop! If I crop the image it won't be centered with respect to the plot box, because on the left side there is the YLabel. How should i modify the code so that the left space out of the box is equal to the space on the right (empty)?

In order to make the code compatible with later MATLAB versions, you can change the code on line 14 in "using_hg2(fig)".

It should now be:
tf = ~verLessThan('matlab','8.4.0');

Earlier it was:
tf = ~graphicsversion(fig, 'handlegraphics');

Hi,

When I use export_fig to create .eps figures, both the x label and y label are not centered with respect to the axes; instead they are centered with respect to the cropped figures. I am using MATLAB2016a on a 64bit Ubuntu system. The following code can be used to demonstrate the problem described above:

x=0:0.001:3*3.1415926;

y=sin(x);

plot(x,y,'r');

axis([0 3*3.1415926 -1 1]);

xlabel('xxxxxxxxxxxxYxxxxxxxxxxxx','FontSize',16);

ylabel('yyyyyyyyyyyyXyyyyyyyyyyyy','FontSize',16);

export_fig test.eps -painters -r500 -q100 -cmyk -transparent;

Please help solve this problem. Many thanks!

Hi there, this tool is very capable. I have been looking for a similar tool to help me export a 3D plot with large amount of data that allows me to encode the axes/text differently from the data.

I came across epscombine and figure2eps but the tools are outdated. (see my question in the link below).

I wonder if you would consider adding those features to export_fig? Or does matlab natively already support them?

Firstly: I love your script Yair, it's great and I use it alot! It really produces nice figures!

Secondly: I got a problem lately. I currently writing my dissertation thesis so I would like all my PDFs in CMYK colorspace, which worked fine for the first figure I made (I think at least).
But with another figure, I run into troubles as it seems not to save the PDF content in CMYK space. I am not sure how to check on it (only finding expensive tools for this) but when I open it in CMYK color space in Illustrator, colors change dramatically... I get the following warning when executing the script with these parameters (-pdf -cmyk -r300):

Warning: Multiple images & lines detected. In such cases, the lines might
appear with an invalid color due to an internal MATLAB bug (fixed in R2014b).
Possible workaround: add a '-depsc' or '-opengl' parameter to the export_fig command.

Very precious tool, thanks a lot for that.

If it can help people: I had a problem using export_fig on figures created with functions of the mapping toolbox. The coast lines I was plotting together with my data were visible on the matlab figure but not on the file created by export_fig. To solve that I have used the uistack function to push my coast lines on top of the figure. For example:

line_coast=load('coast'); h_cl=plotm(line_coast.lat,line_coast.long,'k-');
% insert here complex mapping toolbox plotting operations
uistack(h_cl,'top');
export_fig('my_files.png')

With export_fig and bibget, writing papers is much more fun! :-)

@MSch - export_fig works well on R2015b. The removal of the builtin Matlab ghostscript does not affect export_fig, since export_fig does not depend on it. You can install ghostscript executable directly from http://www.ghostscript.com and then export_fig will use it.

I remind everyone that I will not respond to feature requests or bug reports in this comments section - if you have something to request or to report then use Github's issues page to report and track your issue: https://github.com/altmany/export_fig/issues

Wonderful code

Great tool, really improves the look of my graphs. Only thing so far is that cropping is either on or off, with no option to crop only top/bottom or left/right. I need this to have proper scaling of the plotbox area in Latex files. I had to fix it by just disabling left/right cropping in the crop_borders.m file disabling it for good. Would be great to have specific command for left/right/top/bottom cropping on or off. That's just a minor thing though.

Ben Webber

Great tool.

However, it seems that when text objects are positioned using normalized units, these positions are not properly retained when exporting the figure. I regularly use normalized units as I find these more intuitive. I'm using Matlab 2015b on MacOS 10.9 (the problem also occurs on Matlab 2012b).

By the way the 1 star rating was an accident. I rate this file 6/5.

I have also noticed greek letters distorted when using export_fig. I used to export as -png with compression -m3.
Exporting to pdf file removes the greek letters problem, and increases the quality of the plot.

William

I use this all the time to create plots, and it has been great! Recently I've noticed it does not create Greek letters correctly in the title. There is another post on Github noting the same problem for Matlab 2015a. I'm using Matlab 2014b on Windows 7. Does anyone know why this is happening or how to fix it?

Thanks for the help!

Hi

This is working great for me with exception of using it with the function Magnify on Figure. http://www.mathworks.com/matlabcentral/fileexchange/26007-on-figure-magnifier

For some reason, when Export_Fig runs, the x-axis of some of the magnified figures changes to become illegible. Its almost like some additional decimal places are added to the x-axis and they all overlap each other. As soon as Export_Fig is done, the axis goes back to normal.

Any help on this would be appreciated.

This is my favorite tool to export graphics. However i found that i am not able to export markers that have a certain amount of alpha parameter(yes i found a way to do it and maybe you can find it if you dig on internet). When i export to eps the effect of shade in the background of the marker disappear. The way that i can set transparency in markers is the following:

sMarkers=h1.MarkerHandle; %h1 is line handle
sMarkers.FaceColorData = uint8(255*[0;0;0;0.5]); %fourth element allows setting alpha
sMarkers.EdgeColorData = uint8(255*[0;0;0;0]);

Hi there,

This is a great code but I cannot seem to understand that when I try to use export_fig with larger font sizes, a grey box appears over my axis labels when I try to export the figure in a higher resolution. This is slowly driving me insane and I cannot seem to find anything on it. Perhaps it is my graphics card? Or just me? I use something like this for instance:

export_fig 'filename.png' -png -opengl -r150;

It's an amazing tool.

Thanks for maintaining to support 2014 and 2015 MATLAB versions.

I am wondering why the font is extremely small under linux? I have tried both gentoo and ubuntu, the problem persists. matlab version also have been tested but all ends up with very small fonts.

Thanks

Hi.. Actually i used this code last year to save fig as pdf and append the same, and it worked great..
but now when I try to use 'append', unwanted patches appear on the appended pdf file. I am using MATLAB 2014b. Will you be able to help me out.??
otherwise, the code works great.!! superb job!!

Great tool

I have a problem with the exported .png file. The exponential notation on the top of the left Y axis does not show in the png exported image. Has anyone experienced this?
For instance I have a plot with value 0 to 5 "x10^-12". The exponential shows at the top of the axis but none of the formats I have tried (eps, pdf, jpg, png) show it.

Otherwise, nice work!

It always displays a white diagonal stripe from botton left to bottom left to top right. This occurs no matter which colormap is used. Has anyone tried it on 2015a so far?

Converting a figure with non-standard screen size to pdf on Unix fails
-----------------------------------------

I am trying to convert figures with non-default screen sizes into pdfs:

% open matlab figure file
h=openfig_default(fig_file_name);

% change figure size to non-default size
set(h,'units','normalized','outerposition',[0.1 0.1 0.5 0.5]);

% convert fig file to pdf
export_fig('out.pdf','-pdf', h, '-nocrop','-transparent','-painters', '-append');

This works nicely on Windows, but on Unix the figures in the pdf all have the same default size. Any ideas?

Hi,
I had used this program successfully in the past for printing figures made in matlab. But now I am having a problem. I am trying to print a high resolution map made using geoshow in matlab mapping toolbox. But when I execute the command say export_fig finename.png -r600, the file is saved but only the axis labels are printed, and not the whole figure. I can still print several other figures successfully, so the problem must be related to the mapping toolbox. Could you please help?
Thank you very much.

@Aniket - yes, export_fig does indeed accepts a handle to a figure/axes/uipanel

To all the others - you need to report the issue in the GitHub, otherwise they will not be tracked or fixed: https://github.com/altmany/export_fig/issues

Aniket Vagha

Brilliant tool! Image quality in pdfs is really good.

I was wondering if in case of multiple figures, could we use figure handles when using export_fig?

Elizabeth Jones

Great code! It worked without any fiddling in R2014b and created high-quality PDFs that I can use for professional presentations, posters, and publications. Thanks a lot for making and maintaining this code.

I have the legend at the Southoutside with horizontal orientation. When the box of the legend is set to 'off', a little bit bottom part of the legend is also cropped when exporting figure to eps and pdf (no problem with png). There is a no problem with box outline. The problem persists in MATLAB R2014b.

Does anyone else have similar issue?

Thanks.

Kai Shi

I added a rectangle box in the figure and change the transparency of the box to 0.3. However, when I export the figure into latex. The transparency of the box is still 100%. With and without the -transparent option shows the same results. The code of generating the box is shown below:

annotation(hCCs,'rectangle',rectSize,...
'FaceColor','r','FaceAlpha',0.3,...
'LineStyle','none');

Thank you for this library, it is really usefull! Unfortunately, I am having serious issues with export_fig, specifically with the fileparts(tempname) portion of the code that specifies a temporary folder that the program uses to create/delete temp images. It is trying to use the system32 folder for one of our users and it is giving him access violation errors and crashing. I would like to be able to specify my own user specified temporary path on his computer that he does have read/write access to. This is not a capability of the tool out of the box but could be a simple optional addition that would save us a lot of grief. For now, I will have to do this myself on my export_fig copy. Thanks!

Hi,

First thanks a lot for providing such a wonderful toolbox!

However, here I've found a bug when I switch to Matlab 2014b. In Matlab R2014b, when I was using the toolbox to generate pdf figure as:

export_fig ConvEstimateatten -pdf -transparent

The margin of the figure is not cropped as desiered. Could you have a look at it?

Thanks!

Hi,

I've got another issue: How can I save the file in a different subfolder. I created a subfolder Fig and then, tried:

but that gave

Hi,

I'm still a bit puzzled how to display tex symbols. For instance, one of my titles is
title('\pi^w')
and is properly displayed in the figure, but not the printed pdf (there, I get a colon to the power of w). I'm using the latest version of texshop 3.49.
Thanks!

To clarify, I'm trying to export a plot with a legend from a GUI axis using export_fig(handles.myaxis, filename). The legend does not show. If I plot with a legend from the command window and save the figure with export_fig the legend shows correctly.

@Ian Zammit - the utility's changelog is listed at the bottom of this webpage.

@Linh, Ruben, Iain - please create corresponding issues in Github (check if the issue already exists there, before posting a new one). I have just received ownership of export_fig's maintenance and it could take me some time to dive into things and be able to fix them, so please be patient.

@Ragheb - try to update your ghostscript executable to the latest version. Perhaps your existing executable is incompatible with your platform and causes this crash.

Hi Oliver,

Thanks for an excellent function!

I am using a current version of export_fig (today), OS X 10.10.1, ghostscript 9.15, and Matlab 2014b. All works fine when I set up a figure and run:

export_fig(fname,'-pdf',fh);

However, if I then run:

>> set(groot,'Units','normalized')

I now get:

>> export_fig(fname,'-pdf',fh);

The output is now a blank PDF. Clearly, I can work around this by not invoking:

That said, it would be nice to have export_fig resilient to this setting.

Philipp: There is absolutely no chance without an issue raised on GitHub.

usr0815

Is there any chance that there will be a fix for the totally "jagged" lines all along a graph when exporting to either of those formats: png, eps, pdf, ... ??

The strange thing is: if I use saveas PNG, the Problem is not occuring. With export_fig (PNG) is occurs. So I suppose export_fig first creates a vector format and afterwards a PNG of it, which can explain that.

Anyway: I need MATLAB 2014b for some other features and ask myself if there is any chance to get this bug fixed?

Oliver Woodford

Valjean, R2D2: For the 100th time (and beginning to wonder what is wrong with people), I do not address issues placed in the comments. If you want me to look at your problem, raise a GitHub issue and we can talk.

Valjean

Update: export_fig works fine on the screen-sized figures when I remove the
'-transparent' argument.

Valjean

I want to clarify my previous comment. The script worked for the normal-sized figures, but the one that it choked on was the size of the screen if that makes any difference or helps diagnose the problem.
I create the figure, then resize the figure using the following lines of code:
h=figure;
set(h, 'Position', get(0,'ScreenSize'));

The figures that did save successfully were those that had not been resized.
Any thoughts?

Valjean

Thank you for this script, Oliver. I've been using it successfully for the past few years. However, I recently upgraded from MATLAB 2009 to 2012b, and I'm having nothing but problems. First, I had the same error that Derek got (posted 07 Jun 2013). So, I downloaded the latest version just now and re-ran. Now, I am getting the following error:

update for mac users: I may have found the issue. If you have texshop installed make sure you are at version 3.44.

Thank you for this great function! Just one question: even when I use the -native option the final resolution of the image is different than the size of the matrix that has gone into the image. E.g., I have a 2048x2048 image, but after using export_fig (with the -native option) it returns a 2052x2052 image [currently using '-m4 -bmp -native' as options]. If I don't use that option it returns a 3176x3176 image.

Do you have a suggestion as how to get the exported image to match the size of the matrix?

The function is magnificent.
Except that sometimes for me a problem arises when exporting!

In loglog plot, the label ticks are not written correctly, I mean they should be something like 10^(2), but they are 100.

Strange is that this only happens for y-axis and x-axis is fine!

I looked it up a lot in the internet, but could not find the solution. I have not been able to resolve it by changing tickmode to manual or etc.

Any other solution?

Thanks!

I encountered a similar issue as described by Emma. However, it works fine for linewidths>0.75 pt, but for smaller linewidths the lines seem to be set to 0.75 pt when exporting, i.e. when exporting lines of 0.5 pt width (or any value<0.75), it will export them as 0.75 pt, when exporting lines with 1 pt width (or any value >0.75 pt) it exports them with the correct width.
The problem does not occur in R2014a.

I absolutely love this tool, but I have a problem using 2014b. The lines on my exported figures are really wide now. The exact same code run in 2014a is perfect, but the new linewidths are unusable.

Oliver: I accidentally did not use the most recent release of your script. After updating, it works as great as before in 2014b as well. Thank you.

Yisheng Xu

It's a great tool. The only flaw that I found is the LineWidth and FontSize of exported vector image (pdf) is slighlty bigger than the sizes specified in MATLAB (e.g., LineWidth becomes 0.735pt and unadjustable; FontSize of 10pt becomes 10.29pt) Any way to fix it? Thanks!

Oliver Woodford

Fabian: R2014b works for me. If you have a reproducible error I suggest you provide me the code in an issue on github.

I love this function and use it almost daily to export Matlab figures to pdf and postprocess them in other programs.

However, in Matlab 2014b Mathworks introduced the new graph design and the export to pdf/eps is not possible anymore, giving the error:

Error using eps2pdf (line 100)
Error: /undefined in bdef
Operand stack:

I would highly appreciate if this could be fixed to run with the most recent Matlab version.

Selecting the location for the system version of ghostscript did not work for me. I am using matlab 2014a on a mac (10.9.4). My ghoscript installation is via MacPorts, and installs in /opt/local/bin/gs. My default shell is csh, not bash.

I was able to get the ghostscript.m script to work by changing the mac-specific 'export DYLIB...' commands (bash syntax) to 'setenv DYLIB....' (csh syntax).

I did not find an easy way to check what shell the user is using, but perhaps some checking for this could be added. Since the fix requiring the environment variable to be set has been around for about a year in your code, I suspect not many users have csh as their default shell, either under unix or OSX systems.

I have been using export_fig for several years, and am glad to have it back with my new laptop.

I use imagescnan quite a bit. However, I can't export those figures as pdf since the white patches masking the nan areas are always dropped when using export_fig. I can't seemt to find a way to keep the patches. Exporting using standard pdf export works fine in this regard, yet it's very clumsy.... that's why export_fig is always first :)

Hi Oliver, still having problems exporting patches and lines or symbol.

Hello,

Thanks a lot for that beatiful code. Works quite good.
However, there is a bug: one cannot use the symbol "%" within the file name:

When I type: export_fig(f3, 'Post-Process Estimates - diff. weight (+5 +10 +15)kg, Amp 10','-pdf','-q0','-a1','-r160','-nocrop') % lowest quality, no anti-aliasing, reduced resolution

it creates a nice pdf.

However when I add the symbol "%" at the end of the name, that is: Amp 10% I get a strange error message:

>> export_fig(f3, 'Post-Process Estimates - diff. weight (+5 +10 +15)kg, Amp 10%','-pdf','-q0','-a1','-r160','-nocrop')

xlabel('x-axis'),ylabel('y-axis'),title('title'),legend('function')

code:
% auto plotter
t=0:.001:2;
y1=2*sin(2*pi*t);
y3=2/3*sin(2*pi*3*t);
y5=2/5*sin(2*pi*5*t);
Y=[y1;y3;y5];
% real code begins here
n=size(Y,1);
for x=1:n;
taggy=sprintf('C=%d mF',x); % title
file_name= sprintf('plot_%d.png',x); % file name to be plot_x.png
plot(t, Y(1,:));title(taggy);

2. A problem: If a plot contains an "impoint" or "impoly", or probably any of these interactive objects from image processing toolbox, the output of export_fig simply doesn't show them. The problem happens only when exporting an axes not the whole figure. I would very much appreciate any suggestion?

First of all: great tool! I'm using it a lot.
Second: Matlab FileExchange Commenting is driving me nutts :-) (should've peeked into the previous comment)
Third: (main reason for my post) I encountered a tiny bug in the script, appearing as follows:
1. Create a figure
2. Create multiple axes inside
3. Draw imagesc in each axis
4. Disable axis labelling (axis off)
5. Draw e.g. a coloured rectangle in each image
=> The export will show the rectangle black in all but the first axis

Minimal example:

figure;
set(gcf,'Position',[0 0 1000 500]);
axes('position',[0.0 0.0 0.5 1]);
imagesc(rand(24,24));
axis off
rectangle('position',[8 8 8 8],'EdgeColor','r','LineWidth',2);
axes('position',[0.5 0.0 0.5 1]);
imagesc(rand(24,24));
axis off
rectangle('position',[8 8 8 8],'EdgeColor','r','LineWidth',2);
colormap gray

Sorry for the multiple posts, apparently I can't rate it then comment without it automatically submitting my rating.
Anyways, love it so far, thank you!

I'm trying to resolve 2 odd issues. First, the negative signs on my axes tick labels show up as empty boxes when I open the pdf in Adobe Reader, which makes me think there is a missing font package etc. in my Adobe install; however, when I open the pdf in Ghostscript there is no symbol at all (minus sign or empty box), just the number on each axis tick. I'm using Adobe Reader XI which came installed on a new Dell PC (< 6 mos. old), and I just downloaded Ghostscript 9.10 today.

Second issue is that when I export as a png or tiff the code seems to shift text boxes around; i.e. my axis labels and an additional text box I added to the figure are in different locations than I explicitly set in the code and how they appear in the MATLAB figure (R2011a Student Version).

Any leads or similar issues? Thanks in advance.

Edison: Set the figure width to 17.3cm, and set the output dpi using the -r300 option in the call to export_fig. If that figure is still too large for your screen, then halve the figure size and double the resolution. If you want the tiff width to say 17.3cm in this case then output the bitmap as an argument from export_fig, and save it yourself using imwrite (setting the 'Resolution' option to 300).

Edison

Edison (view profile)

An essential addition to MATLAB, they should include this as standard in future releases. Great.

One question: does export_fig always use the dimensions of the onscreen figure as a guide? For example, I want to export my figure as a TIFF at 300dpi, with a width of 17.3cm. This equates to an image 2049 pixels wide, and this will not fit on my screen. Thanks for the help.

I do have, however, a small question:
I'm trying to export a plot of a uniform distribution between, say, a and b, to the .png format. This obviously means that the function is zero for values lower than a and higher than b. In that case, the function gets overlapped by the axis and is therefore not visible in the exported .png. It is in the MatLab figure. Am I missing something or is there a fix for this? Thanks in advance

Long time user of export_fig here. great function -- thanks!

New machine today. 64 bit Windows 8.1, MATLAB 2013B. Latest installation of Ghoscript (9.1) put onto the machine.

A problem occurs with the function ghostscript.m

On executing the code in this m file: check_gs_path(path) a zero is returned.

This causes the software to ask where the location of the ghostscript executable is -- i point it to the correct dir and it fails to find it.

Thus I have had to hard code in

path = 'C:\Program Files\gs\gs9.10\bin\gswin64c.exe';

before check_gs_path(path) is called, which works.

What's going on?

I am using figures with contour lines, thus my figures are: axes > contourgroup > patch objects.

In my exported images, I was getting the axes with all text label objects but no lines.

I had to change line 97 in isolate_axes.m from allchild() to findall() as a fix. I don't know if this breaks anything but it shouldn't as findall just finds all objects lower in the hierarchy than the one passed in, which is the axes handle in this case. I was losing the patch objects that make up the figure as allchild() was only returning the objects at the first level under the axes.

However, I wish to export to a pdf with a white background. Then I have to do 'set(gcf, 'Color', 'w');' every time. Is there a permanent setting or a parameter that can be set?

I do not get this error when I am not using HG2, but it would take awhile for me to convert everything back from HG2. Do you have any ideas how to fix the problem?

(Note, laprint also doesn't seem to work with HG2. So, this could be a problem with HG2 and not have anything to do with your files.)

David: The grid lines are the width specified (by setting the axes line width), but the segments are shorter (there's no option to change this). Try using thicker grid lines.

Excellent work, many thanks! Question though, I'm finding that when printing, the only objects not reproduced "as shown" are the gridlines. The output gridlines are much fainter and barely visible. Any way to address this? Thanks!

Oliver,

I have just downloaded your code and it seems to be receiving great reviews. I can't seem to get it to work though... All i want to do is to save a figure window to my desktop.

I have a figure that is displaying an image. How would I use export_fig to save this figure under the name 'test' in png format?

This is what I am seeing: (H is set to be the figure handle)

>>export_fig('/Users/maxnorris/Desktop/test','png',H)

Following two comments are mine.

I said I am using "uicomponent" for my GUI.

Actually, I am using " "GUI Layout Toolbox".

I am sorry for the misinforming.

Ozan Oguz

I realised something:

I am using "uicomponent" for my GUI.
After giving "print" command (export_fig),my GUI changes.

What changes exactly?

1) All "uiextras.Empty" objects seem to vanish.

2) Legend in the axes becomes uneditable.

For now, this is what I observed.

Ozan Oguz

This seems to be a great app, thx!

I have a question/problem:

I designed a GUI using uicomponent.m from file exchange. Left part is for controls, right part is for axes.

When I try to export the image of this axes, two different things happen for bitmap and vector formats. 1) For pdf, it gives me only the axes, and this is what I want, but 2) For png or jpg, it also gives me the empty area behind the control buttons on the left side of the axes.

I want a bitmap image with only the axes. Nothing more.

Can you help me, please, Oliver?

Hi Oliver,
Let me add my voiceto the chorus: "Fantastic work!" :)

Now, I notice one thing you change is the grid lines to "- Improved line and grid line styles"
Which in my plot have been "No grid lines"

It would be nice to have the option of keeping the grid lines as shown, and keep your "Improved line and grid lines" as default

I looked into the code but couldn't figure where you're not adding the grid lines to the pdf

Will you create such an option (keep grid lines)? Will you tell me how?

Cheers!

Wonderful performance with fast help from Oliver as if online talk! Save memory and run-time with '-a1' option while keeping quality as plotted, applying it as follows:
set(gcf,'color','w')
export_fig(filename,'-png','-a1','-nocrop')

Oliver Woodford

Tim: You're missing the -nocrop option.

Tim Garrett

Terrific function, but I am unclear on one thing. I wish to create a little booklet of figures where the page size and axis locations are precisely defined. e.g.
h = figure;
set(h,'units','inches','position',[0 0 8.5 11]);

plot(x,y);
set(gca,'Position',[0.2, 0.2, 0.6, 0.6];

Using 'print', my printed figure is placed exactly where I want within the page I want (albeit with stupid matlab problems). With 'export_fig' however, the output is *only* of the figure. The figure is not within a page.

What am I missing?

Thanks.

Great package. You can safely detect Ghostscript under Windows by reading the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Artifex\GPL Ghostscript" (if 64bit) or "HKEY_LOCAL_MACHINE\SOFTWARE\Artifex\GPL Ghostscript" (if 32bit).

Use Matlab's winqueryreg() function or execute "reg" via system() to read the Windows registry.

Keep up the good work!

Dear Oliver,
thank you for this helpful function. In general, it workds fine. But when there are more than one font types are not in the matlab_fonts list, the function will give error :
Error in print2eps (line 97)
font_swap{3,a} = fonts{font_swap{1,end}(1)};

it seems that the equation should be:
font_swap{3,a} = fonts{font_swap{1,a}(1)};

BTW, do you know how to use font types which are not in matlab_fonts list, e.x. Garamond, Palatino Linotype?

thank you.

Igor: You cannot specify the screen resolution in a call to export_fig. However, you can specify your figure size in units that are independent of pixel pitch, such as 'cm'. I suggest you try that.

Igor

Igor (view profile)

Great script.
A question: how can I specify screen resolution while saving figure as .eps?
At the moment, the use of print2eps for the same figure gives different results (different scales) on computers with different screen resolutions (Matlab 2012a x64, Win7 x64 on both of them).
Thank you for your help.

I solved this issue by clearing the LD_LIBRARY_PATH enviroment variable before executing gs by replacing

system(sprintf('"%s" %s', gs_path, cmd));

with

system(sprintf('export LD_LIBRARY_PATH=""; "%s" %s', gs_path, cmd));

in the ghostscript.m file. Maybe this will help in case of other ghostscript issues as well.

I want to export a figure to a .png and I want my linetypes and gridlines to be scaled correctly, so I've got to use the 'painters' renderer. The axis border ('box') is exported under the plot which means it gets covered by the plotted points. This does not happen with the default renderer.
If I change the axes layer to 'top' then the border comes to the top but so do the gridlines. Is there a way of having only the axes border at the top but not the gridlines?

Thanks for the script Oliver... been using it for a long time now and it fills a big gap in MATLAB.

m_user: You can export a particular axes in a figure just by passing in a handle, but there is no support for rendering just part of an axes - I do not intend to implement this either.

Hi Oliver, "short" question: I built a GUI with a handles.axes in which a greyscale image is in the background and a colored, semitransparent image is in the foreground. Now I want to save this overlayed image but I have no variable which "points" to that overlay (so I can't write export_fig Test.fig). Is there another way (e.g. write export_fig gca..) to reference on the handles.axes? thanks in advance..

Oliver Woodford

arnold: The goal of export_fig is to export what is on screen. By all means write a script that makes your figure the right size, have the correct line widths, fonts, etc., then calls export_fig with the correct resolution. Or use one of the several submissions that already do this.

arnold

Hi,
I've got another proposition: rescale figure

To make 'export_fig' even more useful for publications it'd be awesome if you added the possibility to rescale the figure to a certain size.
example:

export_fig 'test.png' -w5 -h4 -r300

This would set the width to 5" and the height to 4" and then export at 300dpi.
For us non-americans it'd be great if you added size in metric units [cm] as well.

export_fig 'test.png' -wm5 -hm4 -r300

would then set the width to 5cm etc.

Hello Oliver, I have noticed that cropping does not always happen for a figure with an array of, say, 5 by 5 subplots. It leaves the margins on the left, top, and right sides of a figure as they are while cropping out the bottom margin. How should I address this? Thanks a lot!

Great set of functions! May I propose an improvement of "eps2pdf" ?
I had to add this at line 54 (after crop cmd) in order to modify the final pdf orientation:

options = [options ' -dEPSCrop -c "<</Orientation 3>> setpagedevice"'];

Maybe the orientation could be given as an input argument?

For information:
* -c "<</Orientation 3>> setpagedevice" -- sets landscape orientation;
* -c "<</Orientation 0>> setpagedevice" -- sets portrait orientation;
* -c "<</Orientation 2>> setpagedevice" -- sets upside down orientation;
* -c "<</Orientation 1>> setpagedevice" -- sets seascape orientation.

latex formulas are distorted/upscaled and displayed incorrectly, but they appear right in the actual figure.

example:
======================
text(xpos,ypos,'$$\frac{\alpha}{\sqrt{2}}\cdot', num2str(1e5),'s$$','HorizontalAlignment', 'left', 'BackgroundColor', [.7 .9 .7], 'interpreter','latex');
======================
it looks right in the figure yet, when export_fig is used, the output image (of whatever kind) shows:

- latex formula is scaled up = bigger
- background of formula doesn't fir anymore (because it's not scaled)
- latex formula is buggy, the '2' is upscaled, yet the square root is not

Maybe you can get around to implementing this as well. Makes it a bit useless for me since I usually have to have formulas in my legends or annotations.

great work!
but I found something wrong:
scatter(rand(10,1),rand(10,1),50);
export_fig('1.png',gca)
and the axes in 1.png is empty.
the matlab function allchild can't find the children of a handle whose type is 'hggroup'(e.g. scatter hggroup).
I modified the allchildren function in isolate_axes.m:
function ah = allchildren(ah)
ah = allchild(ah);
if iscell(ah)
ah = cell2mat(ah);
end
ah = ah(:);
for i = 1:numel(ah)
if strcmp(get(ah(i),'type'),'hggroup')
t =allchildren(ah(i));
ah(end+1:end+numel(t)) = t;
end
end
return
and it worked.

Hi, Oliver,
I had played around with the relevant commands to copy figures as high-resolution bitmaps, using the undocumented "hardcopy" function suggested by TMW staff
e.g. hardcopy(hF_StatsAVI, '-Dopengl', '-r100')
In comparison, your function is more convenient to use, and much better documented.

I am using it to save out PNG files with either whigte or transparent figure background. However, I was baffled when running the same commands which had been succesful previously began outputting images with black backgrounds, despite my setting
set(gcf, 'color','white');
The problem seems to be that it is necessary to _manually_ select "Use figure color" in the "Copy Options" dialogue box, under "Edit" from the figure's menu bar.
I would normally want to produce a metafile with "Transparent background" when _copying_ the figure, except for some recalcitrant plots; hence, I don't usually have "Use figure color" selected.
I thought it might be possible to toggle this programatically, but the command
set(gcf, 'InvertHardCopy', 'off');
was not effective.

Anyway, these issues seem to point to flaws in MATLAB, rather than in your code.

~~~~~

By the way
set(gcf, 'color','none');
is generates this message:
"Warning: Setting the ColorSpec to 'none' for a figure will not be allowed in a future release."
It still works at the moment, and personally I would rather it continued to work. I hope it is replaced by an alternative, and not just removed.
