Detailed Description

ResizeSqrPixel supports the following interpolation modes:

*   NPPI_INTER_NN
*   NPPI_INTER_LINEAR
*   NPPI_INTER_CUBIC
*   NPPI_INTER_CUBIC2P_BSPLINE
*   NPPI_INTER_CUBIC2P_CATMULLROM
*   NPPI_INTER_CUBIC2P_B05C03
*   NPPI_INTER_SUPER
*   NPPI_INTER_LANCZOS
* 

ResizeSqrPixel attempts to choose source pixels that would approximately represent the center of the destination pixels. It does so by using the following scaling formula to select source pixels for interpolation:

*   nAdjustedXFactor = 1.0 / nXFactor;
*   nAdjustedYFactor = 1.0 / nYFactor;
*   nAdjustedXShift = nXShift * nAdjustedXFactor + ((1.0 - nAdjustedXFactor) * 0.5);
*   nAdjustedYShift = nYShift * nAdjustedYFactor + ((1.0 - nAdjustedYFactor) * 0.5);
*   nSrcX = nAdjustedXFactor * nDstX - nAdjustedXShift;
*   nSrcY = nAdjustedYFactor * nDstY - nAdjustedYShift;
* 

In the ResizeSqrPixel functions below source image clip checking is handled as follows:

If the source pixel fractional x and y coordinates are greater than or equal to oSizeROI.x and less than oSizeROI.x + oSizeROI.width and greater than or equal to oSizeROI.y and less than oSizeROI.y + oSizeROI.height then the source pixel is considered to be within the source image clip rectangle and the source image is sampled. Otherwise the source image is not sampled and a destination pixel is not written to the destination image.

Error Codes

The resize primitives return the following error codes:

    - ::NPP_WRONG_INTERSECTION_ROI_ERROR indicates an error condition if
      srcROIRect has no intersection with the source image.
    - ::NPP_RESIZE_NO_OPERATION_ERROR if either destination ROI width or
      height is less than 1 pixel.
    - ::NPP_RESIZE_FACTOR_ERROR Indicates an error condition if either nXFactor or
      nYFactor is less than or equal to zero or in the case of NPPI_INTER_SUPER are not both downscaling.
    - ::NPP_INTERPOLATION_ERROR if eInterpolation has an illegal value.
    - ::NPP_SIZE_ERROR if source size width or height is less than 2 pixels.
