One pointer that does not work as expected

screenDataPnt is (screenWidth * screenHeigth * 4) which in my case is 640*480*4

Your image data is stored in BGRA format? I think you want to swap the bytes you read for B and R in the for loop.

My data is stored in BGRA, so that part is correct.

More of a coding style thing, but:

Code:

		blue[i]  = *(texture + 0);
		green[i] = *(texture + 1);
		red[i]   = *(texture + 2);
		trans[i] = *(texture + 3);

I find it clearer to use index formatting:

Code:

		blue[i]  = texture[0];
		green[i] = texture[1];
		red[i]   = texture[2];
		trans[i] = texture[3];

When you say "more and more corrupted", can you describe what happens to the data?
