SubtractImageHalves
Subtracts the bottom half of the kernel image buffer from the top half. The bottom
half of the buffer starts at buffer[ 0 ] or CController::mapFd[ 0 ] and the top
half starts at buffer[ 0 ] + ( rows * cols ) / 2 or CController::mapFd[ 0 ] +
( rows * cols ) / 2.
Syntax
void SubtractImageHalves( rows, cols );
Parameters
long rows |
The total image row size ( in pixels ). |
long cols |
The total image column size ( in pixels ). |
Returns
None

std::runtime_error
Remarks
Example
// This code demonstrates how to subtract
// the two sides of an image to produce a
// subtracted 512x1200 pixel image from a
// 1024x1200 pixel image.
