mlib_ImageClearEdge(3MLIB)				    mediaLib Library Functions					mlib_ImageClearEdge(3MLIB)

NAME
mlib_ImageClearEdge - sets edges of an image to a specific color SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageClearEdge(mlib_image *img, mlib_s32 dx, mlib_s32 dy, const mlib_s32 *color); DESCRIPTION
The mlib_ImageClearEdge() function sets edges of an image to a specific color. This function can be used in conjunction with the convolve and other spatial functions to fill in the pixel values along the edges. The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. 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

NAME
mlib_ImageMulAlpha_Inp - alpha channel multiplication, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageMulAlpha_Inp(mlib_image *srcdst, mlib_s32 cmask); DESCRIPTION
The mlib_ImageMulAlpha_Inp() function multiplies color channels by the alpha channel on a pixel by pixel basis, in place. For the MLIB_BYTE image, it uses the following equation: srcdst[x][y][c] = srcdst[x][y][c] * srcdst[x][y][a] * 2**(-8) For the MLIB_SHORT image, it uses the following equation: srcdst[x][y][c] = srcdst[x][y][c] * srcdst[x][y][a] * 2**(-15) For the MLIB_USHORT image, it uses the following equation: srcdst[x][y][c] = srcdst[x][y][c] * srcdst[x][y][a] * 2**(-16) For the MLIB_INT image, it uses the following equation: srcdst[x][y][c] = srcdst[x][y][c] * srcdst[x][y][a] * 2**(-31) where c and a are the indices for the color channels and the alpha channel, respectively, so c != a. PARAMETERS
The function takes the following arguments: srcdst Pointer to source and destination image. cmask Channel mask to indicate the alpha channel. Each bit of the mask represents a channel in the image. The channel corresponding to the 1 bit of cmask is the alpha channel. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
