So like I said, why don't you post a few of them? ("Few" means more than one, by the way, because I'm assuming that they won't all be cropped at the same locations otherwise it would be exceedingly trivial) For example, you can post to http://drop.io (no account creation necessary), or some other site that you may have an account with already.

From: ImageAnalyst on 15 May 2010 19:20 I did. It seems to work although the image extracted from the figure is black and white (grayscale actually) and the colormap seems to be null unlike what you see when you open the fig file (which shows a pseudocolored image). But it does retrieve the image values correctly. Maybe I'm just not used to working with colormaps - I rarely apply them, and never save and retrieve them from a file. fullFileName = 'C:\Documents and Settings\user\My Documents\Temporary stuff\m11.fig'; inputFigHandle = open(fullFileName); childImages = findall(inputFigHandle, 'type', 'image'); % <- depends on what data you're looking for... storedColormap = findall(inputFigHandle, 'type', 'Colormap'); % <- depends on what data you're looking for... imageOnly = get(childImages, 'cdata'); %imshow(imageOnly, 'Colormap', storedColormap); % fail imshow(imageOnly, []); set(gcf, 'Position', get(0,'Screensize')); % Maximize figure. title('Image Extracted from the Figure', 'FontSize', 30);
