UserFuncPixel

The type of user-defined

functions that perform point

operations simultaneously on

all channel values of a pixel

in an image.

The prototype specified by the callback function of type

IplUserFuncPixel must be as follows:

typedef void (__STDCALL *IplUserFuncPixel)(IplImage*

srcImage

, void*

srcPixel

, IplImage*

dstImage

, void*

dstPixel

);

srcImage

The source image header (used by the

function to determine the source image

depth and number of channels).

dstImage

The destination image header (used by the

function to determine the destination image

depth and number of channels).

srcPixel

Pointer to the array of channel values of the

source pixel.

dstPixel

Pointer to the array of channel values of the

destination pixel.

Discussion

Function of the type IplUserFuncPixel performs user-defined point

operations on a source image pixel by processing all channel values of a

given pixel simultaneously. The

srcPixel

and

dstPixel

pointers must

be converted by the user function to arrays of source and destination

channel values that have respective bit depths.

To use the function for image processing, its name must be passed to the

calling function

iplUserProcessPixel() as the last parameter in the

arguments list.
