Parameters

dstRoiSize   Destination image ROI size.
dstStep   Destination buffer step size (width of the buffer in bytes).
interpolation   Specifies the method of interpolation.
pDst   Pointer to a location in a destination buffer.
pDst[3]   Pointer to a location in a three-channel planar destination buffer (array values point to a location in each plane).
pDst[4]   Pointer to a location in a four-channel planar destination buffer (array values point to a location in each plane).
pSrc   Pointer to a location in a source buffer.
pSrc[3]   Pointer to a location in a three-channel planar source buffer (array values point to a location in each plane).
pSrc[4]   Pointer to a location in a four-channel planar source buffer (array values point to a location in each plane).
srcRoi   Source image ROI.
srcSize   Source image size.
srcStep   Source buffer step size (width of the buffer in bytes).
xFactor   Factor value for X axis direction.
yFactor   Factor value for Y axis direction .

Description

These functions step through an ROI in a source buffer and map the source data into a destination ROI, using x-y scaling factors and a specified method of interpolation.

A super-sampling interpolation option can be used when both the x and y scaling factors are less than 1.

The following interpolation modes are available.

 FWI_INTER_NN: nearest neighbor interpolation
 FWI_INTER_LINEAR: linear interpolation
 FWI_INTER_CUBIC: cubic interpolation
 FWI_INTER_SUPER: supersampling
 FWI_INTER_LANCZOS: interpolation with Lanczos window function

Use the super-sampling interpolation option when both the x and y scaling factors are less than 1.
