[Jiro Doke]

I guess your question doesn't make sense. What do you mean by "pixel position". In my answer, id1, id2, id3, id4 are pixel positions. So I just provided an answer where you extract a region of an image defined by those 4 positions.

Please be more precise with your problem statement. Note that the body text of your question just says "selc_region". What does that even mean? Also, tell us what you have tried and where exactly you are struggling. Providing code samples you tried would be best.
