Hi,

I'm having a problem with extracting an image that I plot in a figure:

fig = figure
imshow(myimage)
%At the end I extract the plot from the figure in this way
Sf=getframe(fig);
[X,map]=frame2im(Sf);

So in X I obtain the plot, the problem is that the X image, contain also the grey boarder that matlab display around the plot in the figure. How can I save in X only the plot without the gray boarder?

You try this:

set(gca,'position',[0 0 1 1],'units','normalized')
