NAME

       mlib_ImageRotate_Fp - rotate image

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status  mlib_ImageRotate_Fp(mlib_image  *dst,  const  mlib_image *src, mlib_d64 angle, mlib_d64 xcenter, mlib_d64 ycenter, mlib_filter
       filter, mlib_edge edge);

DESCRIPTION

       The mlib_ImageRotate_Fp() function rotates a floating-point source image around a user-defined rotation center in the 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 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

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
