what does that exactly mean?
Posted by Ilya Schabanov on October 07, 2001 at 11:06 AM
hi!
Is there anyone who can explain me what this exactly means...
(i know the result...but cant understand how it comes to it)
using the pixelgrabber class i grab a pixel...
and extract the colors....hmm...i copied this from an example...and dont understand what the operators mean and what for is everything
int p=_pixels[index];
_alpha = (p >> 24) & 0xff;
_red = (p >> 16) & 0xff;
_green = (p >> 8) & 0xff;
_blue = (p ) & 0xff;
i get the right values for the colors... but how??
what does the '>>' mean and what for is '&', how do they exactly work?
thx
-ilya
