/** FillGraphicPrimitive2D class
|
|
|
|
This class defines a bitmap filling for a rectangular area. The
|
|
Range is defined by the Transformation, the fill by the FillGraphicAttribute.
|
|
There, the fill consists of a Bitmap (not transparent) defining the fill data
|
|
and a Point/Vector pair defining the relative position/size [0.0 .. 1.0]
|
|
inside the area where the bitmap is positioned. A flag defines then if this
|
|
is tiled or not.
|
|
|
|
Renderers should handle this primitive; it has a geometrically correct
|
|
decomposition, but on pixel outputs the areas where the tiled pieces are
|
|
aligned tend to show up (one overlapping or empty pixel)
|
|
|
|
SDPR: support alpha directly now. If a primitive processor
|
|
cannot deal with it, use it's decomposition. The decomposition
|
|
uses create2DDecompositionOfGraphic, there all paths are now
|
|
capable of handling a given alpha, including metafile, SVG and
|
|
animated graphics
