mlib_ImageDivAlpha_Fp_Inp(3MLIB) mediaLib Library Functions mlib_ImageDivAlpha_Fp_Inp(3MLIB)NAMEmlib_ImageDivAlpha_Fp_Inp - alpha channel division, in placeSYNOPSIScc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDivAlpha_Fp_Inp(mlib_image *srcdst, mlib_s32 cmask);DESCRIPTIONThe mlib_ImageDivAlpha_Fp_Inp() function divides floating-point color channels by the alpha channel on a pixel-by-pixel basis, in place. It uses the following equation: srcdst[x][y][c] = srcdst[x][y][c] / srcdst[x][y][a] where c and a are the indices for the color channels and the alpha channel, respectively, so c != a. The operation follows the IEEE-754 standard.PARAMETERSThe 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 correspond- ing to the 1 bit of cmask is the alpha channel.RETURN VALUESThe function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOmlib_ImageDivAlpha(3MLIB), mlib_ImageDivAlpha_Fp(3MLIB), mlib_ImageDivAlpha_Inp(3MLIB), attributes(5) SunOS 5.10 10 Nov 2004 mlib_ImageDivAlpha_Fp_Inp(3MLIB)
