Class ColorLinearGradientPaint

Namespace

Egami.Fonts

Assembly

Egami.Fonts.dll

A linear gradient filling the clip: the color line runs from P0 toward P1, with lines of equal color parallel to P0–P2, as COLR defines it.

Constructors

ColorLinearGradientPaint(Vector2, Vector2, Vector2, ColorLine)

A linear gradient filling the clip: the color line runs from P0 toward P1, with lines of equal color parallel to P0–P2, as COLR defines it.

public ColorLinearGradientPaint(Vector2 P0, Vector2 P1, Vector2 P2, ColorLine Line)

Parameters

P0 Vector2

The start point.

P1 Vector2

The end point.

P2 Vector2

The point giving the direction of the lines of equal color.

Line ColorLine

The color line.
