Thank you for your response. I have it made that way and it works perfectly. The thing is that now I wanted to do it with B4Xpages and ZoomImageView, but I don't know how to extract the color from the position where the user clicks. Upvote 0

I have declared a couple of global variables and I can already know in which position (x,y) the user has clicked. Now I want to know the color of that position, but at the moment I don't know how to do it. Thank you. Upvote 0
