Export Matlab figure as PNG?

Question

I need to automatically export figures from Matlab to PNG. My figure has a size of 600x200 px:

hFig = figure(1); 
set(hFig, \'Color\', [1 1 1]); % background         


        

Answer 1

Based upon bdecaf's answer:

set(gcf,'PaperUnits','inches','PaperSize',[600/96,200/96],'PaperPosition',[0 0 600/96 200/96])
print('-dpng','-r96','test')

96 is the dpi of my system. This gives me EXACTLY the same output as the save function. For Windows the dpi is typically 96, sometimes 120. Simply adjust it accordingly to your system. Note that on a beamer the DPI might again be different from your system, especially if your system has 120 DPI! 96 DPI should in general be a quite safe choice for beamers I think. Google if you need help finding out the DPI setting of your system. This answer is 99,9% based on bdecaf and Florian, so I will leave bdecaf's answer selected as the right one.

edit: 600 = horizontal image size in px, 200 = vertical image size in px
