mlib_ImageZoomTranslateToGray - zoom, with translation, and convert to grayscale SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoomTranslateToGray(mlib_image *dst, const mlib_image *src, mlib_d64 zoomx, mlib_d64 zoomy, mlib_d64 tx, mlib_d64 ty, mlib_filter filter, mlib_edge edge, const mlib_s32 *ghigh, const mlib_s32 *glow); DESCRIPTION
The mlib_ImageZoomTranslateToGray() function will enlarge or minify the source binary image by the X and Y zoom factors, with translation, and convert the resulting image into a grayscale image. It uses the following equation for coordinate mapping: xd = zoomx*xs + tx yd = zoomy*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 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. It must be of type MLIB_BYTE and have just one channel. src Pointer to source image. It must be of type MLIB_BIT and have just one channel. zoomx X zoom factor. zoomx > 0. zoomy Y zoom factor. zoomy > 0. tx X translation. ty Y translation. filter Type of resampling filter. It must be MLIB_NEAREST. 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 ghigh Pointer to value for '1' pixels in source image. glow Pointer to value for '0' pixels in source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageZoomTranslateTable(3MLIB) mediaLib Library Functions mlib_ImageZoomTranslateTable(3MLIB) NAME
mlib_ImageZoomTranslateTable - zoom, with translation, with table-driven interpolation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoomTranslateTable(mlib_image *dst, const mlib_image *src, mlib_d64 zoomx, mlib_d64 zoomy, mlib_d64 tx, mlib_d64 ty, const void *interp_table, mlib_edge edge); DESCRIPTION
The mlib_ImageZoomTranslateTable() function will enlarge or minify the source image by the X and Y zoom factors, with translation. It uses a table, interp_table, to do interpolation. It uses the following equation for coordinate mapping: xd = zoomx*xs + tx yd = zoomy*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 data type of the images can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. 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. zoomx X zoom factor. zoomx > 0. zoomy Y zoom factor. zoomy > 0. tx X translation. ty Y translation. interp_table Pointer to an interpolation table. The table is created by the mlib_ImageInterpTableCreate() function. 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_EXTEND_INDEF MLIB_EDGE_SRC_PADDED RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
