cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageScale2_Inp(mlib_image *srcdst, const mlib_d64 *alpha, const mlib_d64 *beta);
The mlib_ImageScale2_Inp() function performs an in-place linear scaling on the pixels of the source image by multiplying the data by a scale factor and then adding an offset. Images can have 1, 2, 3, or 4 channels.
The following equation is used:
srcdst[x][y][i] = srcdst[x][y][i] * alpha[i] + beta[i]
If the result of the operation underflows/overflows the minimum/maximum value supported by the destination image, then it will be clamped to the minimum/maximum value respectively.
The image can be of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT or MLIB_INT.
The function takes the following arguments:
srcdst
alpha
beta
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
