Description ​

TCustomSampler is the abstract base class for all sampling engines in Graphics32. It provides a generalized interface for retrieving 32-bit ARGB color values (TColor32) at coordinate locations specified in integer, 16.16 fixed-point (TFixed), or single-precision floating-point (TFloat) formats.

Sampler implementations can represent procedurally generated patterns, color gradients, coordinate transformations, nested sampler chains, or bitmap resamplers.

Before performing intensive sampling loops, callers must call PrepareSampling to allow the sampler (and any nested child samplers) to initialize internal caches or lookup tables. After sampling is complete, FinalizeSampling should be called to release temporary resources.
