Description

Functions and Procedures

function FracToRainbow(const Fraction: real): TColor;

FracToRainbow converts a fraction between 0 and 1 to a color using the selected TModel.ColorScheme in FracAndSchemeToColor.

procedure ReadRealArray(const Reader: TReader; var Positions: TOneDRealArray; const Count: integer);

ReadRealArray is used to read a one-dimensional array of real numbers from a stream. See DefineProperties

procedure WriteRealArray(const Writer: TWriter; const Positions: TOneDRealArray);

WriteRealArray is used to write a one-dimensional array of real numbers to a stream. See DefineProperties

procedure ReadIntegerArray(const Reader: TReader; var Positions: TOneDIntegerArray; const Count: integer);

ReadIntegerArray is used to read a one-dimensional array of integers from a stream. See DefineProperties

procedure WriteIntegerArray(const Writer: TWriter; const Positions: TOneDIntegerArray);

WriteIntegerArray is used to write a one-dimensional array of integers to a stream. See DefineProperties
