Parameters
- pSpec
- Pointer to the spec structure for the resize filter.
- borderSize
- Size in pixels of necessary borders.
Description
This function computes the size of the source image ROI that is used by the corresponding resize transform and is out of the processing boundaries for Luma and Chroma planes. The
pSpec
parameter defines the resize algorithm parameters. Prior to using the
ippiResizeYUV420GetBorderSize
function, you need to initialize the
pSpec
parameter by calling one of the following functions:
ippiResizeYUV420LanczosInit
or
ippiResizeYUV420SuperInit
.
The returned border size is in Luma/Chroma plane pixels. This means that the chosen resize algorithm uses the returned outer size of the source image ROI for each plane.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error if one of the specified pointers isNULL.
- ippStsContextMatchErr
- Indicates an error if pointer to the spec structure is invalid.
