Syntax

)
IW_DECL(IppStatus) iwiRotate(
const IwiImage *pSrcImage,

Parameters
pSrcImage |
Pointer to the source image. |
||||||||
pDstImage |
Pointer to the destination image. |
||||||||
angle |
Angle of clockwise rotation in degrees. |
||||||||
interpolation |
Interpolation method. The supported values are ippNearest, ippLinear, and ippCubic. |
||||||||
pAuxParams |
Pointer to the auxiliary parameters structure. If NULL, default parameters are used. | ||||||||
border |
Extrapolation algorithm for out of image pixels processing. Supported values:
|
||||||||
pBorderVal |
Pointer to an array of values to assign to pixels of the constant border, one element of the array for each channel of the image. This parameter is applicable only to the ippBorderConst border type and can be NULL for other border types. |
||||||||
pTile |
Pointer to the IwiTile structure for tiling. If NULL, the whole image is processed. |
Auxiliary Arguments
Argument | Default Value | Description |
---|---|---|
reserved |
0 |
Reserved value. |
Description
This function performs rotation of the image around (0,0). This is a simpler version of the iwiWarpAffine function designed specifically for rotation.
This function supports the following features:
Feature | Support |
---|---|
Internal threading | No |
Manual tiling | No |
IwiTile simple tiling | Yes |
IwiTile pipeline tiling | No |
Return Values
ippStsInterpolationErr |
The interpolation value is illegal. |
ippStsDataTypeErr |
The dataType value is illegal. |
ippStsNumChannelsErr |
The channels value is illegal. |
ippStsBorderErr |
The border value is illegal. |
ippStsNotSupportedModeErr |
The selected combination of parameters' values is not supported. |
ippStsNoMemErr |
Failed to allocate memory. |
ippStsSizeErr |
Values of the size fields are illegal. |
ippStsInplaceModeNotSupportedErr |
In-place operation is not supported: pSrcImage is equal to pDstImage. |
ippStsNullPtrErr |
At least one of the pointers (except pBorderVal and pTile) is NULL. |
ippStsNoErr |
No errors. |
ippStsNoOperation |
Warning: width and/or height of the image is equal to zero. |
ippStsWrongIntersectQuadr |
Warning: transformed source image has no intersection with the destination image. |
