Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- srcRoiSize
- Size of source image ROI, in pixels.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- dstRoiSize
- Size of destination image ROI, in pixels.
- pState
- The pointer to the pyramid layer structure.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function creates an upper pyramid layer pDst from the source image pSrc. The function performs upsampling of the source image and then applies the convolution kernel using the mirror border. Before calling the ippiPyramidLayerUp function, compute the size of the pyramid layer structure pState using the PyramidLayerUpGetSize function and initialize the structure using the PyramidLayerUpInit function. The function can process images with srcRoiSize not greater than the roiSize parameter specified in the PyramidLayerUpInit function.
This function uses the mirrored border.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error if one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if srcRoiSize or dstRoiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error condition if srcStep is less than srcRoiSize.width * <pixelSize> , or dstStep is less than dstRoiSize.width * <pixelSize>. |
ippStsNotEvenStepErr |
Indicates an error condition if one of the step values is not divisible by 4 for floating-point images, or by 2 for short-integer images. |
ippStsBadArgErr |
Indicates an error condition if pState->rate has wrong value. |
