mlib_ImageSub2_Fp_Inp(3MLIB)				    mediaLib Library Functions				      mlib_ImageSub2_Fp_Inp(3MLIB)

NAME

       mlib_ImageSub2_Fp_Inp - subtraction, in place

SYNOPSIS

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

       mlib_status mlib_ImageSub2_Fp_Inp(mlib_image *src2dst, const mlib_image *src1);

DESCRIPTION

       The  mlib_ImageSub2_Fp_Inp()  function  subtracts  the  second  floating-point source image from the first floating-point source image on a
       pixel-by-pixel basis, in place.

       It uses the following equation:

       src2dst[x][y][i] = src1[x][y][i] - src2dst[x][y][i]

PARAMETERS

       The function takes the following arguments:

       src2dst	       Pointer to second source and destination image.

       src1	       Pointer to first source image.

RETURN VALUES

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

NAME

       mlib_ImageBlend2_Fp_Inp - blend with an alpha image

SYNOPSIS

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

       mlib_status mlib_ImageBlend2_Fp_Inp(mlib_image *src2dst,
	    const mlib_image *src1, const mlib_image *alpha);

DESCRIPTION

       The mlib_ImageBlend2_Fp_Inp() function blends two images together, in place, on a pixel-by-pixel basis using an alpha image, when a is also
       on a pixel basis. The alpha image can be a single-channel image or have the same number of channels as the source and destination images.

       It uses the following equation when the alpha image is a single-channel image:

	 src2dst[x][y][i] = alpha[x][y][0]*src1[x][y][i] +
			    (1 - alpha[x][y][0])*src2dst[x][y][i]

       It uses the following equation when the alpha image has the same number of channels as the source and destination images:

	 src2dst[x][y][i] = alpha[x][y][i]*src1[x][y][i] +
			    (1 - alpha[x][y][i])*src2dst[x][y][i]

       It uses the following equation:

PARAMETERS

       The function takes the following arguments:

       src2dst	  Pointer to second source and destination image.

       src1	  Pointer to first source image.

       alpha	  Alpha image used to control blending. The pixels in this image should have values in the range of [0.0, 1.0].

RETURN VALUES

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