NAME
mlib_ImageBlendColor_Inp - blend an image and a color, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendColor_Inp(mlib_image *srcdst, const mlib_s32 *color, mlib_s32 cmask); DESCRIPTION
The mlib_ImageBlendColor_Inp() 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_BYTE images, the alpha coefficients are in Q8 format. For MLIB_SHORT images, the alpha coefficients are in Q15 format and must be positive. For MLIB_USHORT images, the alpha coefficients are in Q16 format. For MLIB_INT images, the alpha coefficients are in Q31 format and must be positive. 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: srcdst Pointer to the source and destination 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

NAME
mlib_ImageBlendColor_Fp_Inp - blend an image and a color, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendColor_Fp_Inp(mlib_image *srcdst, const mlib_d64 *color, mlib_s32 cmask); DESCRIPTION
The mlib_ImageBlendColor_Fp_Inp() 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: srcdst Pointer to the source and destination 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
