Abstract
In a method of compositing graphic elements in a pixel-based renderer, a first graphic element is received having a first color and a first opacity, and a second graphic element is received having a second color and a second opacity. A blend output is obtained from a blend function dependent on the first color and the second color, and a resultant color is determined of a compositing operation on the first and second graphic elements, with the resultant color being dependent on the blend output and otherwise being independent of the second color.
