NAME
mlib_ImageAffineIndex - affine transformation on a color indexed image
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageAffineIndex(mlib_image *dst, const mlib_image *src, const mlib_d64 *mtx, mlib_filter filter, mlib_edge edge, const void *colormap);
DESCRIPTION
The mlib_ImageAffineIndex() function does affine transformation on a color indexed image according to the following equation: xd = a*xs + b*ys + tx yd = c*xs + d*ys + ty where a point with coordinates (xs, ys) in the source image is mapped to a point with coordinates (xd, yd) in the destination image. The image data type must be MLIB_BYTE or MLIB_SHORT. The width and height of the destination image can be different from the width and height of the source image. The center of the upper-left corner pixel of an image is located at (0.5, 0.5).
PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. mtx Transformation matrix. mtx[0] holds a; mtx[1] holds b; mtx[2] holds tx; mtx[3] holds c; mtx[4] holds d; mtx[5] holds ty. filter Type of resampling filter. It can be one of the following: MLIB_NEAREST MLIB_BILINEAR MLIB_BICUBIC MLIB_BICUBIC2 edge Type of edge condition. It can be one of the following: MLIB_EDGE_DST_NO_WRITE MLIB_EDGE_DST_FILL_ZERO MLIB_EDGE_OP_NEAREST MLIB_EDGE_SRC_EXTEND MLIB_EDGE_SRC_PADDED 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.
