mlib_ImageThresh3(3MLIB) mediaLib Library Functions mlib_ImageThresh3(3MLIB)NAMEmlib_ImageThresh3 - image thresholdingSYNOPSIScc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh3(mlib_image *dst, const mlib_image *src, const mlib_s32 *thresh, const mlib_s32 *ghigh);DESCRIPTIONThe mlib_ImageThresh3() function compares each pixel in the source image to a threshold value. If the pixel is less than or equal to the threshold value, then the destination pixel is set to the value of the source pixel. If the pixel is greater than the threshold value, then the destination pixel is set to the high output level. It uses the following equation: dst[x][y][i] = src[x][y][i] if src[x][y][i] <= thresh[i] dst[x][y][i] = ghigh[i] if src[x][y][i] > thresh[i]PARAMETERSThe function takes the following arguments: dst Pointer to destination image. src Pointer to source image. thresh Threshold value. thresh[i] contains the threshold for channel i. ghigh High output level. ghigh[i] contains the high output level for channel i.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_ImageThresh1(3MLIB), mlib_ImageThresh1_Fp(3MLIB), mlib_ImageThresh1_Fp_Inp(3MLIB), mlib_ImageThresh1_Inp(3MLIB), mlib_ImageTh- resh2(3MLIB), mlib_ImageThresh2_Fp(3MLIB), mlib_ImageThresh2_Fp_Inp(3MLIB), mlib_ImageThresh2_Inp(3MLIB), mlib_ImageThresh3_Fp(3MLIB), mlib_ImageThresh3_Fp_Inp(3MLIB), mlib_ImageThresh3_Inp(3MLIB), mlib_ImageThresh4(3MLIB), mlib_ImageThresh4_Fp(3MLIB), mlib_ImageTh- resh4_Fp_Inp(3MLIB), mlib_ImageThresh4_Inp(3MLIB), mlib_ImageThresh5(3MLIB), mlib_ImageThresh5_Fp(3MLIB), mlib_ImageThresh5_Fp_Inp(3MLIB), mlib_ImageThresh5_Inp(3MLIB), attributes(5) SunOS 5.10 10 Nov 2004 mlib_ImageThresh3(3MLIB)
