Save image without the white margin

Hi, Please I want to use the HGEXPORT function as shown:

hgexport(gcf, 'figure1.jpg', ...

     hgexport('factorystyle'), 'Format', 'jpeg');

hgexport(gcf, 'L2w.jpg', hgexport('factorystyle'), 'Format', 'jpeg');

But, I dont need the white margin around the image.

There are many solutions. The best standby solution is to (almost) always use export_fig. It crops the white space by default unless you specify the -nocrop option.

Please I need more explanation about using export_fig.

In fact, every thing was normal before I change my system to windows 8. Now I have a problem with the following commands:

hgexport(gcf, 'L2w.jpg', hgexport('factorystyle'), 'Format', 'jpeg');

There is a white margin around the image, in windows 7 I didn't have this problem as the image is saved without any margin, it seems so strange to have this problem now.

Please check out the 2 images attached.
