Parameters

srcVolume	Size of the source volume.
srcVoi	Region of interest of the source volume.
dstVoi	Region of interest of the destination volume.
coeffs	Affine transform matrix.
nChannel	Number of channel or planes, possible value is 1.
interpolation	Type of interpolation, the following values are possible: IPPI_INTER_NN- nearest neighbor interpolation, IPPI_INTER_LINEAR- trilinear interpolation, IPPI_INTER_CUBIC- tricubic interpolation, IPPI_INTER_CUBIC2P_BSPLINE- B-spline, IPPI_INTER_CUBIC2P_CATMULLROM- Catmull-Rom spline, IPPI_INTER_CUBIC2P_B05C03- special two-parameters filter (1/2, 3/10).
pSize	Pointer to the size of the external buffer.

Description

This function calculates the size (in bytes) of the external buffer that is required for the ipprWarpAffine function. (In some cases the function returns zero size of the buffer).

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error when pSizeor coeffsis `NULL`.
ippStsSizeErr	Indicates an error if width, or height, or depth of the srcVoi or dstVoi is less than, or equal to zero.
ippStsNumChannelErr	Indicates an error when nChannel has an illegal value.
ippStsInterpolationErr	Indicates an error when interpolation has an illegal value.
