Color Inversion: With a black and white image, color inversion
doesn't really do much and so you should go out and find a more colorful
image to manipulate before doing this assignment. Below is the basic code
which is used for color inversion. Since you will be using an image you find
out there in internetland, you will have to figure out its width and height
in order to get all the PixelGrabber code to work right.
<![CDATA[
for(int x = 0; x< w * h; x++){
int r = (pixel[x] & 0x00ff0000)>>16;
int g = (pixel[x] & 0x0000ff00)>>8;
int b = (pixel[x] & 0x000000ff);
r=255-r;
g=255-g;
b=255-b;
pixel[x]= (255<<24) | (r<<16) | (g<<8) | b;
}
