mlib_ImageBlendRGBA2ARGB(3MLIB) 			    mediaLib Library Functions				   mlib_ImageBlendRGBA2ARGB(3MLIB)

NAME
mlib_ImageBlendRGBA2ARGB - image blending and channel reordering SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendRGBA2ARGB(mlib_image *dst, const mlib_image *src); DESCRIPTION
The mlib_ImageBlendRGBA2ARGB() function blends the source image of the RGBA format into the destination image of the ARGB format. The image type must be MLIB_BYTE. The source and destination images must contain four channels. It uses the following equation: Cd = Cs*As + Cd*(1 - As) Ad = Ad where, Cs and Cd are the RGB color components of the source and destination images, respectively. As and Ad are the alpha components of the source and destination images, respectively. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageBlendColor_Fp - blend an image and a color SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendColor_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *color, mlib_s32 cmask); DESCRIPTION
The mlib_ImageBlendColor_Fp() function blends an image and a color with the alpha channel. It uses the following equation: Cd = Cs*As + Cc*(1 - As) Ad = 1.0 where, Cs and Cd are the RGB color components of the source and destination images, respectively. As and Ad are the alpha components of the source and destination images, respectively. Cc is the color component of the constant color. For MLIB_FLOAT and MLIB_DOUBLE images, the alpha coefficients are assumed to be in the range of [0.0, 1.0]. The images can have two to four channels. The length of color array must not be less than the number of channels in the images. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. color Array of constant color components. cmask Channel mask to indicate the alpha channel. Each bit of cmask represents a channel in the image. The channel corresponding to the highest bit with value 1 is the alpha channel. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
