VideoScaler.getCoeff
const(double) * getCoeff(uint outOffset, out uint inOffset, out uint nTaps)For a given pixel at out_offset, get the first required input pixel at in_offset and the n_taps filter coefficients.
Note that for interlaced content, in_offset needs to be incremented with 2 to get the next input line.
Parameters
outOffset | an output offset |
inOffset | result input offset |
nTaps | result n_taps |
Returns
an array of n_tap gdouble values with filter coefficients.
