Get image from figure

Hello,
I have an image and I would like to zoom in; I use the following code:
%First section
im = imread('mmx1.jpg');
imshow(im);
%%Second Section
figure
imshow(im)
zoom(2.5)
The 'first section' displays one image and the 'second section' returns a 'zoomed in' image. Could you please tell me how to retrieve this 'zoomed in' image in workspace?

The zoomed image contains exactly the same pixels values as the original image, because zooming concerns the view only. So what do you want to obtain exactly? I guess, that imresize will be more useful.

Not sure if you can get the picture back from the image handle. Think of your problem a little bit different though:
A zoom factor of 2 is equivalent to throwing away 8/9 of the picture like this: x x x x 0 x x x x which is equivalent to throwing away half the rows to the left, right, top and bottom of the image. You can easily work your way forward from there for other factors. Regards, Florian
