property Pattern: TFixedSamplePattern;
TFixedSamplePattern = array of array of TArrayOfFixedPoint;
Pattern is a two-dimensional array of TArrayOfFixedPoint. Pixels are super-sampled by collecting sub-samples for each sample coordinate specified in one of the elements of the Pattern. For irregular sampling it is useful to use tiles of irregularly generated samples, since this will reduce aliasing. Thus, the sample pattern can be varied from pixel to pixel by adjusting the size of the Pattern matrix. This will cause the sample pattern to be repeated.
