mlib_ImageRotateIndex - rotate color-indexed image SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageRotateIndex(mlib_image *dst, const mlib_image *src, mlib_d64 angle, mlib_d64 xcenter, mlib_d64 ycenter, mlib_filter filter, mlib_edge edge, const void *colormap); DESCRIPTION
The mlib_ImageRotateIndex() function rotates the source image about a user-defined rotation center in user-defined radians. The width and height of the destination image can be different from the width and height of the source image. The (xcenter, ycenter) point of the source image is mapped to the center of the destination image. You should ensure that the destination buffer is large enough to hold the resulting bounding box to avoid clipping part of the image. The source and destination images must be single-channel images. 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). PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. angle Angle of rotation. The angle is measured in radians clockwise. xcenter X coordinate of rotation center in the source image. ycenter Y coordinate of rotation center in the 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
