How to "Save As .jpg" a figure programmically?

I've got a following problem: I need to automatically save figures as jpg files. This is easily done by hand

(open the File-menu, go to Save As, choose jpg image). But how to do this programmically?

Either by

print(FigureHandle, 'C:\temp\File.jpg')

or

pause(0.02);  % Magic update of java elements - don't ask me why...
F = getframe(FigureHandle);
[X, map] = frame2im(F);
imwrite(X, map, 'C:\temp\File.jpg');

Thanks to Walter and Jan,

Solved the issue using print():

1) take the screencapture and save it to the object as a property

sc=print('-RGBImage');
set(obj,'ScreenCapt',sc);

...

2) later, when saving results, open up a dummy figure (not visible), imshow the screencapture on it and print the figure

into a file.

H=figure('Visible','off');
imshow(get(obj,'ScreenCapt'));
print(H,'screencapt.png','-dpng');
