PyramidLayerUpGetSize

Computes the size of the structure for creating an upper pyramid layer and the size of the temporary buffer.

Parameters

dstRoi: Size of the destination image ROI.
rate: Ratio between neighbouring levels (1 < rate≤ 10).
kerSize: Size of the kernel.
pStateSize: Pointer to the size of the pyramid layer state structure.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function computes the size of the pState structure to build an upper pyramid layer and the size of the temporary buffer, in bytes. This structure is used by the ippiPyramidLayerUp function and can be applied to process images with size not greater than dstRoi. For an example on how to use this function, refer to the example provided with the ippiPyramidLayerDown function description.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when at least one of the pointers is NULL.
ippStsSizeErr	Indicates an error when the width or height of images is less than, or equal to zero.
ippStsBadArgErr	Indicates an error when kerSize is even, or equal to or less than 0; or when rate is out of the range.
