i need an idl programmer to expain to me this code

Hi, I'd like to help with detailed explanation of the given IDL code. I have strong background in image and signal processing.

Dear sir. I have read your description and it's interesting to me. As an experienced data scientist, I am very good at many data processing languages such as interactive data language and python and R etc. I think I could be the right person who can help you. Thank you.

Greetings I've read through the code that you've attached to your job posting. I'm fully able to comprehend the image manipulation operations that are taking place, and I'm confident that if given the flt file which is referenced near the beginning of the program, I'll be able to put them into context. There are also an errors preventing the first window from showing the modified image, which I have already fixed. (I mean that I used a testing image as a substitute). I look forwards to further correspondence
