User Defined Functions

13-5

If saturation of the computed result is necessary, it must be provided within

the user function.

The user function of type IplUserFuncPixel may call IPL_ERROR to set

the IPL error status.

See

iplUserProcessPixel() for more information.

UserProcess

Calls user-defined function

to separately process each

channel value of pixels in an

image with integer data.

void iplUserProcess( IplImage*

srcImage

, IplImage*

dstImage

, IplUserFunc

cbFunc

);

srcImage

Thesourceimage.

dstImage

The destination image.

cbFunc

The pointer to the user-defined function (of

IplUserFunc type).

Discussion

The function iplUserProcess() scans pixels of a source image

srcImage

, retrieves respective channel values, and passes them to the user-

defined function

cbFunc

for processing.

The source image must contain integer data of 8-, 16-, or 32-bit depth.

Before passing channel values to

cbFunc

, the function

iplUserProcess() converts them to int type.

After processing by

cbFunc

, the returned values are saturated to the

destination data range, and written to the respective channel of the

destination image

dstImage

. The saturation is done only for 8- or 16-bit
