PathGradientBrush class (gdipluspath.h)

A PathGradientBrush object stores the attributes of a color gradient that you can use to fill the interior of a path with a gradually changing color. A path gradient brush has a boundary path, a boundary color, a center point, and a center color. When you paint an area with a path gradient brush, the color changes gradually from the boundary color to the center color as you move from the boundary path to the center point.

Inheritance

The PathGradientBrush class implements Brush.

PathGradientBrush::PathGradientBrush Creates a PathGradientBrush::PathGradientBrush object based on a GraphicsPath object.
PathGradientBrush::PathGradientBrush The PathGradientBrush::PathGradientBrush(const PathGradientBrush &) constructor (gdipluspath.h) lists the constructors of the PathGradientBrush class.
PathGradientBrush::PathGradientBrush Creates a PathGradientBrush::PathGradientBrush object based on an array of points. Initializes the wrap mode of the path gradient brush.

PathGradientBrush::SetBlendTriangularShape The PathGradientBrush::SetBlendTriangularShape method sets the blend shape of this path gradient brush.
PathGradientBrush::SetCenterColor The PathGradientBrush::SetCenterColor method sets the center color of this path gradient brush. The center color is the color that appears at the brush's center point.
PathGradientBrush::SetCenterPoint The PathGradientBrush::SetCenterPoint method sets the center point of this path gradient brush. By default, the center point is at the centroid of the brush's boundary path, but you can set the center point to any location inside or outside the path.
PathGradientBrush::SetCenterPoint The PathGradientBrush::SetCenterPoint method sets the center point of this path gradient brush.
PathGradientBrush::SetFocusScales The PathGradientBrush::SetFocusScales method sets the focus scales of this path gradient brush.

PathGradientBrush::SetGraphicsPath The PathGradientBrush::SetGraphicsPath method is not implemented in Windows GDI+ version 1.0.
PathGradientBrush::SetInterpolationColors The PathGradientBrush::SetInterpolationColors method sets the preset colors and the blend positions of this path gradient brush.
PathGradientBrush::SetSurroundColors The PathGradientBrush::SetSurroundColors method sets the surround colors of this path gradient brush. The surround colors are colors specified for discrete points on the brush's boundary path.
PathGradientBrush::SetTransform The PathGradientBrush::SetTransform method sets the transformation matrix of this path gradient brush.
PathGradientBrush::SetWrapMode The PathGradientBrush::SetWrapMode method sets the wrap mode of this path gradient brush.
PathGradientBrush::TranslateTransform The PathGradientBrush::TranslateTransform method updates this brush's current transformation matrix with the product of itself and a translation matrix.

Remarks

By default, the center point of a path gradient brush is the centroid of the boundary path, but you can set the center point to any location, inside or outside the path, by calling PathGradientBrush::SetCenterPoint Methods.

The boundary path can be a polygon specified by an array of points, and each of those points along the boundary can have a different color.

By default, the color is linearly related to the distance as you move from a point on the boundary to the center point. You can customize the relationship between color and distance by calling PathGradientBrush::SetBlend.
