mlib_ImageClearEdge_Fp - sets edges of an image to a specific color SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageClearEdge_Fp(mlib_image *img, mlib_s32 dx, mlib_s32 dy, const mlib_d64 *color); DESCRIPTION
The mlib_ImageClearEdge_Fp() function sets edges of an image to a specific color. This function can be used in conjunction with the con- volve and other spatial functions to fill in the pixel values along the edges. The data type of the image can be MLIB_FLOAT or MLIB_DOUBLE. PARAMETERS
The function takes the following arguments: img Pointer to an image. dx Number of columns on the left and right edges of the image to be cleared. dy Number of rows at the top and bottom edges of the image to be cleared. color Array of color values by channel. color[i] contains the value for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageBlendColor_Fp(3MLIB) mediaLib Library Functions mlib_ImageBlendColor_Fp(3MLIB) 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
