Thread Subject: Poor quality when saving figures as images

I have a routine that processes some data and creates figures as it goes, and I want to know how to programatically save the figures as images, and get the exact same results as I would get via the File > Save As... menu dialog from the figure window.

Currently, if I save a figure through the File > Save As... menu, I'm happy with the way it looks (just like it looks on screen). But if I try to programatically save the same figures using saveas or print like below, they look bad in my opinion. I lose the background color I specified, the aspect ratio isn't what I specified, the font size is huge, etc.
     
saveas(gcf,path,'png');
-OR-
print(gcf,'-dpng',path);

How can I avoid the ugly "default" look and get the same results as when manually saving via the menu?

Thanks!

Hi

I don't know about the same as the Save as.. option, but export_fig generates an image of a figure as it appears on screen. You find it at:

try playing with the papertype, papersize, paperposition etc.
properties of the figure, these will allow you to control the size of
the printed image. There is a print option that lets you choose
whether to include the background colors or not, i forgot what it is
called but it should be in the print documentation.

Thanks! This is doing pretty much exactly what I wanted.
