mlib_VideoP64Decimate_U8_U8(3MLIB)			    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 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.

NAME

       mlib_VideoCopyRef_U8_U8 - copies a block from the reference block to the current block

SYNOPSIS

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

       mlib_status mlib_VideoCopyRef_U8_U8(mlib_u8 *curr_block, const mlib_u8 *ref_block, mlib_s32 width, mlib_s32 height, mlib_s32 stride);

DESCRIPTION

       The  mlib_VideoCopyRef_U8_U8()  function copies a block from the reference block to the current block. The stride applies to both the input
       reference block and the current block.

PARAMETERS

       The function takes the following arguments:

       curr_block      Pointer to the current block. curr_block must be 8-byte aligned.

       ref_block       Pointer to the reference block.

       width	       Width of the blocks.

       height	       Height of the blocks.

       stride	       Stride, in bytes, between adjacent rows in both the current block and the reference block. stride must  be  a  multiple	of
		       eight.

RETURN VALUES

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