mlib_ImageXProj(3MLIB) mediaLib Library Functions mlib_ImageXProj(3MLIB)NAMEmlib_ImageXProj - image X projectionSYNOPSIScc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageXProj(mlib_d64 *xproj, const mlib_image *img);DESCRIPTIONThe mlib_ImageXProj() function computes the sum of the pixels in each column of the source image. The image must be a single-channel image. It uses the following equation: h-1 xproj[x] = SUM img[x][y][0] y=0 where x = 0, 1, ..., w - 1.PARAMETERSThe function takes the following arguments: xproj Pointer to X-projection vector, where length is equal to the number of columns in the source image (in other words, the image width). img Pointer to an input image.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_ImageXProj_Fp(3MLIB), mlib_ImageYProj(3MLIB), mlib_ImageYProj_Fp(3MLIB), attributes(5) SunOS 5.10 10 Nov 2004 mlib_ImageXProj(3MLIB)
