Print to file, saveas, maintaining figure dimensions

Hello All,

I'm creating a single figure with three plots and setting the axes to be equal giving me three square plots (images, actually). This is all done many times with a loop so I'm looking for a coding solution rather than a clicking solution. To reduce the amount of blank space, I adjust the figure window size:

      set(fig,'Position',[100 100 1200 300])

to give a rectangular window. When it is printed or saved to a file:

      print(fig,'-djpeg','filename')

or

      saveas(fig,'filename.extension')

the resulting saved image (jpeg) has the same dimensions as the default figure window. I've seen answers to similar problems that use:

      set(fig,'PaperPosition', [100 100 1200 300])

but that didn't do the trick. In a sentence, I'm looking for the best way to save the figure as an image with specific dimensions. I'd appreciate any suggestions! Thank you.

check this

 t=0:0.1:10;y=sin(t)
plot(t,y);
set(gcf, 'PaperUnits', 'centimeters');
set(gcf, 'PaperPosition', [0 0 10 15]); %x_width=10cm y_width=15cm
saveas(gcf,'fig1.tif')

%if it's for use with word, use the same units then word's

Thanks for your answer, it is most similar to what I was trying. The main difference is in the PaperUnits specification, and it works to accomplish my goal.

I suggest to use export_fig() from the FEX. It also crops the figure grey borders automatically.

% Load and display mandrill

load mandrill
image(X)
colormap(map) 
axis off

% Change axis dimension ...

axis image

% ... or manually

set(gca,'units','pix','pos',[100,100,500,300])

% Export

export_fig('test.jpeg',gca)

Thanks for this, export_fig looks like a useful tool.
