Hi all,

I want to know if a pixel is inside a selection thanks to the txt file that I get after saving the ROI. The text file only give the tops of the polygon selection and what I want to have is a binary mask that distinguish pixel that are in the selection from the other.

Thanks in advance and sorry for my english.
