mlib_ImageColorTrue2Index(3MLIB) mediaLib Library Functions mlib_ImageColorTrue2Index(3MLIB) NAME
mlib_ImageColorTrue2Index - true color to indexed color using nearest matched LUT entries SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageColorTrue2Index(mlib_image *dst, const mlib_image *src, const void *colormap); DESCRIPTION
The mlib_ImageColorTrue2Index() function converts a true color image to a pseudo color image with the method of finding the nearest matched lookup table entry for each pixel. The source image can be an MLIB_BYTE or MLIB_SHORT image with three or four channels. The destination must be a single-channel MLIB_BYTE or MLIB_SHORT image. The last parameter, colormap, is an internal data structure (which includes the lookup table) for inverse color mapping. Create it by call- ing the mlib_ImageColorTrue2IndexInit() function. PARAMETERS
The function takes the following arguments: dst Pointer to destination or destination image. src Pointer to source or source image. colormap Internal data structure for inverse color mapping. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageZoomIn2XIndex(3MLIB) mediaLib Library Functions mlib_ImageZoomIn2XIndex(3MLIB) NAME
mlib_ImageZoomIn2XIndex - 2X zoom on color-indexed image SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoomIn2XIndex(mlib_image *dst, const mlib_image *src, mlib_filter filter, mlib_edge edge, const void *colormap); DESCRIPTION
The mlib_ImageZoomIn2XIndex() function enlarges the source image by a factor of two. It uses the interpolation method as described by the resampling filter. The image data type must be MLIB_BYTE or MLIB_SHORT. The center of the upper-left corner pixel of an image is located at (0.5, 0.5). The width and height of the destination image can be different from those of the source image. The center of the source image is mapped onto the center of the destination image. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. 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. ATTRIBUTES
