mouse input from image?

[dclapp]

Good morning,

I am using Octave 3.0.1 under windows and am using many of the image
processing tools.  I would like to be able to get pixel information off a
figure, once I draw an image.

I am using the imshow(myImg), to draw a greyscale image.  

I would like to be able to drag my mouse over the image and have a print out
of the pixel value on the image.

Any ideas on how to do this?

thanks!

Dan
