);

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 YUY2 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:
ippiResizeYUV422NearestInit
and
ippiResizeYUV422LinearInit
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if one of the specified pointers is
NULL
.
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 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 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).
