Parameters
- srcSize
- Size of the source image, in pixels.
- srcRoi
- Source image ROI (of theIppiRect type).
- dstRoi
- Destination image ROI (of theIppiRect type).
- direction
- Transformation direction. Supported values:
- ippWarpForward
- Forward transformation
- ippWarpBackward
- Backward transformation
- coeffs
- Coefficients for the perspective transform.
- interpolation
- Interpolation mode. Supported values:
- IPPI_INTER_NN
- Nearest neighbor interpolation
- IPPI_INTER_LINEAR
- Linear interpolation
- IPPI_INTER_CUBIC
- Cubic interpolation
- IPPI_INTER_EDGE
- Use edge smoothing in addition to one of the above modes
- pBufSize
- Pointer to the size, in bytes, of the external buffer.
Description
This function computes the size of the external work buffer
required for bilinear warping of the source image ROI. The result is stored in the
pBufSize
parameter.Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error whenpBufSizeisNULL.
- ippStsSizeErr
- Indicates an error when one of the image dimensions is less than, or equal to zero.
- ippStsWarpDirectionErr
- Indicates an error whendirectionhas an illegal value.
- ippStsCoeffErr
- Indicates an error when bilinear transformation is singular.
- ippStsInterpolationErr
- Indicates an error wheninterpolationhas an illegal value.
- ippStsWrongIntersectQuad
- Indicates a warning that no operation is performed if the transformed source image extended with borders has no intersection with the destination image.
