Constructor Detail

LinearGradientBrushBase

protected LinearGradientBrushBase()

Initializes a new instance of the LinearGradientBrushBase class with default parameters. The angle is 45 degrees and the rectangle is located in (0,0) with size (1,1).

LinearGradientBrushBase

protected LinearGradientBrushBase(PointF point1,
                                  PointF point2)

Initializes a new instance of the LinearGradientBrushBase class. The gradient rectangle is claculated from the specified points.

Parameters:

point1 - A PointF structure that represents the starting point of the linear gradient.

point2 - A PointF structure that represents the endpoint of the linear gradient.

LinearGradientBrushBase

protected LinearGradientBrushBase(Point point1,
                                  Point point2)

Initializes a new instance of the LinearGradientBrushBase class. The gradient rectangle is claculated from the specified points.

Parameters:

point1 - A Point structure that represents the starting point of the linear gradient.

point2 - A Point structure that represents the endpoint of the linear gradient.

LinearGradientBrushBase

protected LinearGradientBrushBase(RectangleF rect,
                                  float angle,
                                  boolean isAngleScalable)

Initializes a new instance of the LinearGradientBrushBase class based on a rectangle, starting and ending colors, and an orientation angle.

Parameters:

rect - A RectangleF structure that specifies the bounds of the linear gradient.

angle - The angle, measured in degrees clockwise from the x-axis, of the gradient's orientation line.

isAngleScalable - if set to true the angle is changed during trasnformations with this LinearGradientBrushBase.

LinearGradientBrushBase

protected LinearGradientBrushBase(Rectangle rect,
                                  float angle,
                                  boolean isAngleScalable)

Initializes a new instance of the LinearGradientBrushBase class based on a rectangle and an orientation angle.

Parameters:

rect - A RectangleF structure that specifies the bounds of the linear gradient.

angle - The angle, measured in degrees clockwise from the x-axis, of the gradient's orientation line.

isAngleScalable - if set to true the angle is changed during trasnformations applied to this LinearGradientBrushBase.
