NAME
mlib_ImageConv5x5Index - 5x5 convolution on a color indexed image SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConv5x5Index(mlib_image *dst, const mlib_image *src, const mlib_s32 *kernel, mlib_s32 scale, mlib_edge edge, const void *colormap); DESCRIPTION
The mlib_ImageConv5x5Index() function performs a 5x5 convolution the color indexed source image by using the user-supplied kernel. The source and destination images must be single-channel images. The input and output images must have the same image type and size. For this convolution, the key element of the convolution kernel is located at the center of the kernel matrix. This function performs the convolution on color indexed image. The input image and the output image must be single channel images. The image type must be MLIB_BYTE or MLIB_SHORT. It uses the following equation: m-1-dm n-1-dn dst[x][y][i] = SUM SUM src[x+p][y+q][i]*k[p][q]*2**(-scale) p=-dm q=-dn where m = 5, n = 5, dm = (m - 1)/2 = 2, dn = (n - 1)/2 = 2. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. kernel Pointer to the convolution kernel, in row major order. scale Scaling factor. edge Type of edge condition. It can be one of the following: MLIB_EDGE_DST_NO_WRITE MLIB_EDGE_DST_FILL_ZERO MLIB_EDGE_DST_COPY_SRC MLIB_EDGE_SRC_EXTEND colormap Internal data structure for inverse color mapping. This data structure is generated by the mlib_ImageColorTrue2IndexInit() function. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
