Discussion
The function iplOR() performs a bitwise OR operation between the values
of corresponding pixels of two input images.
Xor
Combines corresponding
pixels of two images by a
bitwise XOR operation.
void iplXor(IplImage* srcImageA , IplImage* srcImageB ,
IplImage*
dstImage );
srcImageA The first source image.
srcImageB The second source image.
dstImage The image resulting from the bitwise operation between
input images
srcImageA and srcImageB .

Image Compositing Based on Opacity
The Image Processing Library provides functions to composite two images
using either the opacity (alpha) channel in the images or a provided alpha
value. Alpha values range from 0 (100% translucent, 0% coverage) to full
range (0% translucent, 100% coverage). Coverage is the percentage of the
pixel’s own intensity that is visible.
