.. instead of a Primitive2DContainer. The container very frequently contains only a single item, since the decomposition method often sticks only a single top-level node in there, so it turns out to be a net loss overall, memory consumption-wise. Also, if we return a single Primitive2DReference from a BufferedDecomposition, that maximises the sharing of data between the BufferedDecomposition objects at the bottom of the decomposed tree, and objects higher up.

|
|
|
|
This class defines a hatch filling for a rectangular area. The
|
|
Range is defined by the Transformation, the hatch by the FillHatchAttribute.
|
|
If the background is to be filled, a flag in FillHatchAttribute is set and
|
|
the BColor defines the background color.
|
|
|
|
#i120230# This primitive is now evtl. metric dependent due to the value
|
|
MinimalDiscreteDistance in the FillHatchAttribute if the value is not zero.
|
|
This is used for a more appealing, VCL-like visualisation by not letting the
|
|
distances get too small between lines.
|
|
|
|
The decomposition will deliver the hatch lines.
