Parameters
srcSize
Size, in pixels, of the source image.
dstSize
Size, in pixels, of the destination image.
xShift
Shift value in the
x
direction.
yShift
Shift value in the
y
direction.
borderType
Type of border. Supported values:
ippBorderTransp
. Outer pixels are not processed.
borderVal
Not used. This parameter is applicable only to the
ippBorderConst
border type.
smoothEdge
Flag for edge smoothing. Supported values:


0 - transformation without edge smoothing.


1 - transformation with edge smoothing.

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 super sampling interpolation method. To calculate the size of the specification structure, call the
ippiResizeGetSize
function.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if one of the specified pointers is
NULL
.
ippStsNoOperation
Indicates a warning if:


- width or height of the destination image is equal to zero.


- smoothing edge is on and width or height of the destination image is equal to one.

ippStsSizeErr
Indicates an error in the following cases:
  • Indicates that one of the specified dimensions of the source image is less than the corresponding dimension of the destination image, or that the width or height of the source or destination image is negative.
  • If the width or height of the source or destination image is negative.
ippStsExceededSizeErr
Indicates an error If width or height of the source or destination image exceeds 33554431 (0x1FFFFFF) (only for platform-aware and TL functions).
ippStsDataTypeErr
Indicates an error if
dataType
has an illegal value.
ippStsNumChannelsErr
Indicates an error if the number of channels is not supported.
ippStsBorderErr
Indicates an error if specified
borderType
is not supported.
