This class encapsulates both two-color gradients and custom multicolor gradients.
All linear gradients are defined along a line specified either by the width of a rectangle or by two points.
By default, a two-color linear gradient is an even horizontal linear blend from the starting color to the ending color along the specified line. Customize the blend pattern using the Blend class, the SetSigmaBellShape methods, or the SetBlendTriangularShape methods. Customize the direction of the gradient by specifying the LinearGradientMode enumeration or the angle in the constructor.
Use the InterpolationColors property to create a multicolor gradient.
The Transform property specifies a local geometric transform applied to the gradient.
The following example creates a horizontal LinearGradientBrush; the color components change linearly as you move from a horizontal coordinate of 0 to a horizontal coordinate of 200. For example, a point whose first coordinate is halfway between 0 and 200 will have a blue component that is halfway between 0 and 255. This example is designed for use with Windows Forms. The following code example is designed for use with Windows Forms, and it requires the PaintEventArgs e, which is a parameter of PaintEventHandler.
