Downsample the vectors Y and (optionaly) X starting at position Index and for Len samples.

Pascal
procedure PixelDownSample(Width: integer; Y: TVec; X: TVec = nil; NX: TVec = nil; Equidistant: TEquidistantSample = eqsXEquidistant); overload;
Description

Store result for Y in the calling vector and the result for X in the NX vector. If X axis is equidistant, you can omit X and NX parameters. Set Width to the number of target pixels. An exception is reaised, if any of the vectors is complex or if array borders are overrun/underrun.
