Hi Sir, can I know how to save the .fig from matlab window to .jpg based on the desired result.this the image that I mentioned: http://www.flickr.com/photos/80166922@N06/7347715732/in/photostream
As u can see from the image, there is white area in the backgeound but I do not want the white are.Just want the region of interest (I mean the circular sign only). how should I eliminate the white background so that I can save it as .jpg for the ROI only. FYI, I save the image from .fig to .jpg in my current directory

Export_fig automatically crops whitespace around figures by default. Download the files to somewhere on your MATLAB path, then, with the relevant figure open, call:
export_fig specific_directory/test.jpg -a1
