ColorToGray | |
|
RGB Color to Gray conversion using user supplied conversion coefficients. Here is how NPP converts gamma corrected RGB Color to Gray using user supplied conversion coefficients. * nGray = aCoeffs[0] * R + aCoeffs[1] * G + aCoeffs[2] * B;
*
For the C4C1R versions of the functions the calculations are as follows. For BGRA or other formats with alpha just rearrange the coefficients accordingly. * nGray = aCoeffs[0] * R + aCoeffs[1] * G + aCoeffs[2] * B + aCoeffs[3] * A;
