Question

Is there a debugger (free if possible) that can visualize image buffers during debugging sessions.
Something like:

1. I stop at breakpoint.
2. Then I select an image buffer, give directions of what the data is – RBG, CMYK, 8bit, float, whatever.
3. I am shown an image (or it is saved) made from the data.

Answer 1

If you are using gdb to debug your program, you can call your own(or some other library functions) that can visualize the image buffer for you(possibly in a separate window) from the gdb prompt once you reach a breakpoint.
