NAME
       mlib_VideoP64Decimate_U8_U8 - averages the source raster image over 2x2 blocks and writes the results to the destination raster image

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoP64Decimate_U8_U8(mlib_u8 *dst,
	    const mlib_u8 *src, mlib_s32 width, mlib_s32 height,
	    mlib_s32 dst_stride, mlib_s32 src_stride);

DESCRIPTION
       The  mlib_VideoP64Decimate_U8_U8()  function  averages  the  source  raster image over 2x2 blocks and writes the results to the destination
       raster image. This function is used when the remote side is only capable of QCIF and our scanned image is source to the encoder in CIF for-
       mat.

PARAMETERS
       The function takes the following arguments:

       dst	     Pointer to the destination raster image.

       src	     Pointer to the source raster image.

       width	     Width of the image.

       height	     Height of the image.

       dst_stride    Stride, in bytes, between adjacent rows in the destination image.

       src_stride    Stride, in bytes, between adjacent rows in the source image.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
