Get Graphics color

Hello everyone

There is a question to ask, if I want to do one effect, to read a region or a pixel of color (including alpha value), and changed the color or pixel area (including the alpha value).

Will There suitable api or plug-in can provide this solution?

Thank you for the answer.

This is a frequently asked question. The answer for now is ‘no’, although it comes up often enough that I’m sure the Corona guys have looked into it. It boils down to the fact that on devices in OGL it is an incredibly slow operation reading and writing individual pixels, to the point where it is to be avoided if at all possible.

Thank rakoonic answer ~

Or look forward to such a function ~

Would really like this feature as well.  Sad to hear it’s such a beast on resources.

Cheers.
