Snapshot

Program to take screenshot of modal GUI figures.

Description

Recently, while preparing a GUI function for submission to the file exchange I wanted to capture a screenshot, but I couldn't easily do it because the GUI function is modal and I couldn't run getframe from the command line. So, I wrote Snapshot. It facilitates taking a screenshot of a modal GUI figure or any other figure for that matter. It's very easy to use and the image is placed in a variable in the base workspace.

• MATLAB release: MATLAB 7.2 (R2006a)
• Other requirements: Tested on Windows XP and Mac OS X.

This is an excellent idea, however the menu function faults. Multiple radio buttons can be chosen and that crashes Matlab. Just typing snapshot in Matlab results in the following errors

S MD,
It looks as though you are using an older version of MATLAB that doesn't support nested functions.
