mediaLib Library Functions     mlib_VideoP64Decimate_U8_U8(3MLIB)



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

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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 format.

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.
