You are a shining example of how NOT to behave on a forum. For the last two months you've been stepping on almost every netiquette rule there is. You've double-posted, used all caps, posed as a "hot girl", consistently asked others to do your work for you, rarely thanked people for their help, posted in the wrong section, etc.

It seems that many posts further, you still haven't shown any improvement in your behavior. Your question is incomprehensible, posted in the wrong section (now moved) and doesn't show your own attempt so far.

Show some effort both with regard to coding and your posts on this forum.

amnon.owed is right.
Well, at least, I appreciate the detailed subject, for a change, although it is a duplicate of the question itself.
And I fear that, like amnon.owed, I don't understand the question...

Perhaps take a look at loadImage(), then at loadPixels() and updatePixels, and thus the pixels[] array.
