WarpAffineGetBufSize

Calculates the size of the external buffer for the affine transform.

Syntax

IppStatus ipprWarpAffineGetBufSize(IpprCuboid srcVoi, IpprCuboid dstVoi, int nChannel, int interpolation, int* pBufferSize);

Parameters

srcVoi	Volume of interest of the source volume.
dstVoi	Volume of interest of the destination volume.
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).
pBufferSize	Pointer to the size of the external buffer.

Description

The function ipprWarpAffineGetBufSize is declared in the ippr.h file.

This function calculates the size (in bytes) of the external buffer that is required for the function ipprWarpAffine ipprWarpAffine. (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 if othe pBufferSize pointer is `NULL`.
ippStsSizeErr	Indicates an error if width, or height, or depth of the srcVoi or dstVoi is less than or equal to 0.
ippStsNumChannelErr	Indicates an error condition if nChannel has an illegal value.
ippStsInterpolationErr	Indicates an error condition if interpolation has an illegal value.
