Hi,

I'm using imwrite to save images on a machine that I'm accessing via remote desktop. This works as expected when the remote desktop screen is maximised. However, if I minimise or close the remote desktop to get on with something else while it's processing, I just end up with blank images.

This is the code I'm using:

        def_back = get(gcf,'Color');        
                set(gcf,'Color',[1 1 1]);
                drawnow
                frame = getframe(gcf);
                image = (frame2im(frame));
                imwrite(image,[<FILENAME> '.png'])
                set(gcf,'Color',def_back);
                drawnow

The observation is correct. getframe does not work outside the visible area of the screen. So this is not a problem of imwrite. Try to replace getframe by:

cdata = print(gcf, '-RGBImage')
