A LinearGradientBrush paints an area with a linear gradient. A linear gradient defines a gradient along a line. The line's end points are defined by the StartPoint and EndPoint properties of the linear gradient. A LinearGradientBrush brush paints its GradientStops along this line.
The default linear gradient is diagonal. In the default, the StartPoint of a linear gradient is (0,0), the upper-left corner of the area being painted, and its EndPoint is (1,1), the lower-right corner of the area being painted. The colors in the resulting gradient are interpolated along the diagonal path.
The following illustration shows a diagonal gradient. A line was added to highlight the interpolation path of the gradient from the start point to the end point.

The next illustration shows the same linear gradient, but with highlighted gradient stops.

It is possible to specify a gradient axis that does not completely fill area being painted. When this occurs, the SpreadMethod property determines how the remaining area is painted.
A LinearGradientBrush is a type of Freezable object and therefore can be frozen to improve performance. For information about Freezable features, such as freezing and cloning, see Freezable Objects Overview.
