mlib_ImageThresh1_Fp(3MLIB) mediaLib Library Functions mlib_ImageThresh1_Fp(3MLIB)NAMEmlib_ImageThresh1_Fp - image thresholdingSYNOPSIScc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh1_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thresh, const mlib_d64 *ghigh, const mlib_d64 *glow);DESCRIPTIONThe mlib_ImageThresh1_Fp() function compares each pixel in the floating-point 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 low output level. If the pixel is greater than the threshold value, then the destination pixel is set to the high output level. The data type of the destination image can be MLIB_BIT or can be the same as the data type of the source image. It uses the following equation: dst[x][y][i] = glow[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. glow Low output level. glow[i] contains the low 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_Inp(3MLIB), mlib_ImageThresh1_Inp(3MLIB), mlib_ImageThresh2(3MLIB), mlib_ImageTh- resh2_Fp(3MLIB), mlib_ImageThresh2_Fp_Inp(3MLIB), mlib_ImageThresh2_Inp(3MLIB), mlib_ImageThresh3(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_ImageThresh1_Fp(3MLIB)
