Parameters
srcSize |
Size, in pixels, of the source image. | ||||||
dstSize |
Size, in pixels, of the destination image. | ||||||
dataType |
Data type of the image. Supported values: ipp8u, ipp16u, ipp16s, ipp32f, ipp64f. | ||||||
hint |
Computation algorithm for processing Ipp8u data. Possible values are:
|
||||||
pSpec |
Pointer to the specification structure for the resize filter. | ||||||
numChannels |
Number of channels. Possible values are 1, 3, and 4. |
Description
This function initializes the specification structure for the resize algorithm with the linear interpolation method. To calculate the size of the specification structure, call the ippiResizeGetSize function.
The function with the parameter hint allows users to choose between a faster but less accurate algorithm and a slower but more accurate one. Without the parameter hint this function initializes the specification structure for the faster but less accurate algorithm for Ipp8u data type.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
ippStsNoOperation |
Indicates a warning when width or height of the image is equal to zero. |
ippStsSizeErr |
Indicates an error if:
|
ippStsDataTypeErr |
Indicates an error if dataType has an illegal value. |
ippStsExceededSizeErr |
Indicates an error If width or height of the source or destination image exceeds 33554431 (0x1FFFFFF) (only for platform-aware or TL functions). |
ippStsNumChannelErr |
Indicates an error if numChannel has an illegal value. |
