GetTilePointer
Returns a pointer to the specified image tile.
Syntax
Case 1: Operation with TL functions based on the Platform Aware API
IppStatus ippiGetTilePointer_32f_LT(const Ipp32f* pSrc, Ipp32f** pDst, IppSizeL srcStep, IppSizeL x, IppSizeL y, Ipp32s numChannels);
IppStatus ippiGetTilePointer_64f_LT(const Ipp64f* pSrc, Ipp64f** pDst, IppSizeL srcStep, IppSizeL x, IppSizeL y, Ipp32s numChannels);
Case 2: Operation with TL functions based on the Classic API
IppStatus ippiGetTilePointer_32f_T(const Ipp32f* pSrc, Ipp32f** pDst, int srcStep, int x, int y, Ipp32s numChannels);
IppStatus ippiGetTilePointer_64f_T(const Ipp64f* pSrc, Ipp64f** pDst, int srcStep, int x, int y, Ipp32s numChannels);

Parameters
| pSrc | Pointer to the source image. | 
| pDst | Pointer to the memory location of the pointer to the destination image. | 
| srcStep | Distance in bytes between consecutive lines in the source image. | 
| x | x coordinate of a tile, in pixels. | 
| y | y coordinate of a tile, in pixels. | 
| numChannels | Number of channels in the image. Possible values are 1, 3, and 4. | 
Description
This function returns a pointer to the specified image tile.
Return Values
| ippStsNoErr | Indicates no error. | 
| ippStsNullPtrErr | Indicates an error condition when the pSrc or pDst pointer is NULL. | 
| ippStsSizeErr | Indicates an error condition when x or y is less than zero. | 
| ippStsNumChannelsErr | Indicates an error condition when numChannels has an illegal value. |
