mlib_ImageRotate_Fp(3MLIB)				    mediaLib Library Functions					mlib_ImageRotate_Fp(3MLIB)

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.

mlib_ImageZoomIn2X(3MLIB)				    mediaLib Library Functions					 mlib_ImageZoomIn2X(3MLIB)

NAME

       mlib_ImageZoomIn2X - 2X zoom

SYNOPSIS

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

       mlib_status mlib_ImageZoomIn2X(mlib_image *dst, const mlib_image *src,
	    mlib_filter filter, mlib_edge edge);

DESCRIPTION

       The mlib_ImageZoomIn2X() function enlarges the source image by a factor of two. It uses the interpolation method as described by the resam-
       pling filter.

       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

RETURN VALUES

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