function GetSampleInt(X, Y: Integer): TColor32;

function GetSampleFixed(X, Y: TFixed): TColor32;

function GetSampleFloat(X, Y: Single): TColor32;

Description

GetSample provides a method for acquiring a color sample from the coordinate (X, Y). The sample may be generated by the sampler itself, or it may be acquired from a nested sampler. Descendants of TCustomSampler must always override at least one of GetSampleFixed or GetSampleFloat.

The different postfixes determines the precision of the input parameters (integer, fixed-point or floating-point).
