mediaLib Library Functions           mlib_ImageSConv7x7_Fp(3MLIB)



NAME
     mlib_ImageSConv7x7_Fp - separable 7x7 convolution

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

     mlib_status mlib_ImageSConv7x7_Fp(mlib_image *dst, const mlib_image *src,
          const mlib_d64 *hkernel, const mlib_d64 *vkernel, mlib_s32 cmask,
          mlib_edge edge);


DESCRIPTION
     The mlib_ImageSConv7x7_Fp() function  performs  a  separable
     7x7  convolution  on  the  source  image  by using the user-
     supplied kernel.


     It uses the following equation:

                      m-1-dm n-1-dn
       dst[x][y][i] =  SUM    SUM  src[x+p][y+q][i]*h[p]*v[q]
                      p=-dm  q=-dn



     where m = 7, n = 7, dm = (m - 1)/2 = 3, dn = (n - 1)/2 = 3.

PARAMETERS
     The function takes the following arguments:

     dst        Pointer to destination image.


     src        Pointer to source image.


     hkernel    Pointer to the horizontal kernel.


     vkernel    Pointer to the vertical kernel.


     cmask      Channel mask to indicate the channels to be  con-
                volved, each bit of which represents a channel in
                the image. The channels corresponding to  1  bits
                are  those  to be processed. For a single-channel
                image, the channel mask is ignored.


     edge       Type of edge condition. It can be one of the fol-
                lowing:
