/** FillGradientPrimitive2D class
|
|
|
|
This class defines a gradient filling for a rectangular area. The
|
|
Range is defined by the Transformation, the gradient by the FillGradientAttribute.
|
|
|
|
The decomposition will deliver the decomposed gradient, e.g. for an ellipse
|
|
gradient the various ellipses in various color steps will be created.
|
|
|
|
I have added functionality to create both versions of filled decompositions:
|
|
Those who overlap and non-overlapping ones. The overlapping version is the
|
|
default one since it works with and without AntiAliasing. The non-overlapping
|
|
version is used in the MetafilePrimitive2D decomposition when the old XOR
|
|
paint was recorded.
