2.1.15 GradientFill Enumeration

  • Article

The GradientFill enumeration defines the modes for gradient fill operations.

 typedef  enum 
 {
   GRADIENT_FILL_RECT_H = 0x00000000,
   GRADIENT_FILL_RECT_V = 0x00000001,
   GRADIENT_FILL_TRIANGLE = 0x00000002
 } GradientFill;

GRADIENT_FILL_RECT_H: Color interpolation along a gradient from the left to the right edges of a rectangle.

GRADIENT_FILL_RECT_V: Color interpolation along a gradient from the top to the bottom edges of a rectangle.

GRADIENT_FILL_TRIANGLE: Color interpolation between vertexes of a triangle.
