I would say that everyone solved the problem, using the above posts
that you read.
Were you unable to?

Hi

The function export_fig, available on the file exchange (http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig), now has the -native option, which will automatically save a figure at the native resolution of an image in the figure.

If you have problems with it please read all the help text to make sure you are using the function correctly, then email me from the author contact page if it still doesn't work.

HTH,
Oliver
