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.
