Reading Image Pixel Location and Value
QUESTION: The RDPIX command I've used forever doesn't seem to work in the new IDL version I just updated to. Do you have a program that does the same thing, but works in this version?
ANSWER: The RDPIX program goes all the way back to almost the first version of IDL! It was written way before widgets were invented.
In any case, here is a Read_Pixel program that does the same thing. You call it like this, passing it a 2D image.
IDL> Read_Pixel, image
