RGB for a given X,Y Coordinate

[74charger]

Hello,

Let's say that I have a UIImageView. Is there a way to get the RGB color for a given X,Y coordinate inside of it?

Thank You.

Thank you for replying.

Yea, I saw this and went through it. It wasn't give me consistent results.

I'll go through it again.

If you can think of anything else, I would appreciate it.

What were the inconsistent results?

Your code needs to handle all the possible color layouts like RGBA, ARGB, 12 bit, 24 bit, 32 bit, LSB, MSB, etc.

I had a little test application with a white .png image with black borders. At times, when I clicked on the black border, the RGB was not 0,0,0 and/or when I clicked in the white area, it was not 255, 255, 255.

Thanks.
