saving plot figures without opening

Hello, I would like to save some plot figures withoput displaying them on the screen. I used

set(fig, 'visible','off')

saveas(fig,'file.fig','fig')

set(fig, 'visible','on')

close(fig

But, what it savves is a blank .bmp file.

Does anyone have an idea?

The saveas, from what i can understand, does a screen capture but since the figure is invisible there isn't anything there. try using the print command to get your bmp.

 print (fig, '-dbmp', 'file.bmp')
