Parameters
- pSpec
- Pointer to the spec structure for the resize filter.
- dstSize
- Size in pixels of the destination image.
- pBufSize
- Pointer to the size in bytes of the external buffer.
Description
This function computes the size of the external buffer for the NV12 resize transform. The
pSpec
parameter defines the resize algorithm parameters. Prior to using the ippiResizeYUV420GetBufferSize
function, you need to initialize the pSpec
parameter by calling one of the following functions: ippiResizeYUV420LanczosInit
and ippiResizeYUV420SuperInit
.Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error ifpBufferSizepointer isNULL.
- ippStsNoOperation
- Indicates a warning if width or height of the destination image is equal to zero.
- ippStsContextMatchErr
- Indicates an error if pointer to the spec structure is invalid.
- ippStsSizeWrn
- Indicates a warning in the following cases:
- if width or height of the image is odd,
- if the destination image size is more than the destination image origin size.
- ippStsSizeErr
- Indicates an error in the following cases:
- if width or height of the image is equal to 1,
- if width or height of the destination image is negative,
- if the calculated buffer size exceeds maximum 32 bit signed integer positive value (the processed image size is too large).
