Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- value
- The constant value to divide each pixel value in a source buffer (constant vector in case of 3- or four-channel images).
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image.
- pSrcDst
- Pointer to the source and destination image ROI for the in-place operation.
- srcDstStep
- Distance in bytes between starts of consecutive lines in the source and destination image for the in-place operation.
- roiSize
- Size of the source and destination ROI in pixels.
- scaleFactor
- Scale factor (see In Integer Result Scaling ).
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function changes image intensity by dividing pixel values of an image buffer by the constant
value
. For multi-channel images, pixel channel values are divided by the components of a constant vector
value
. For complex data, the function processes both real and imaginary parts of pixel values. In case of operations on integer data, the resulting values are scaled by
scaleFactor
and rounded (not truncated).
When the divisor value is zero, the function execution is aborted and the
ippStsDivByZeroErr
error status is set. Note that in the alpha channel case (
AC4
), the alpha channels are not processed.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcStep,dstStep, orsrcDstStephas a zero or negative value.
- ippStsDivByZeroErr
- Indicates an error condition if the divisor value is zero.
