Any of you had ever changed 1 only color in a sprite?
Example :

Change all 255,0,255 in 0,255,255....
There is a way to do this?

Yes i use this in my games, but imagine we have a sprite that have 3 colors as template...
- Yellow
- Purple
- Green

255,255,0
255,0,255
0,255,0

Now i wanna change only the green to red.
So ...
which method is the best to do it without changing yellow and purple??
Is there a way to take Bit per Bit the PNG data? Or i need to develope a new internal function in c++ to manipulate the PNG file?
