XPrimitive2D interface
This is the basic interface for 2D graphic primitives. They need to be able
- to provide a decomposition consisting of simpler graphic primitives
- to provide a 2D bound rectangle as a 2D range
Retrieve bound rect of primitive
This method calculates the actual bound rect of the area in
world coordinates. Note that for view-dependent primitives,
the necessary pixel adjustments are taken into account. For that reason
the ViewParameters need to be given.
2D View-specific parameter set. The defined but not mandatory
parameters include:
::com::sun::star::geometry::AffineMatrix2D Transformation
A transformation matrix which maps between world coordinates (which
is equal to object's local coordinates) to view coordinates. If not
defined, an empty transformation is implied.
::com::sun::star::geometry::RealRectangle2D Viewport
Defines the visible part of the view in world coordinates. May be used
to optimize decompositions, e.g. for 3d scenes only the visible part
needs to be created. If not given, an empty Viewport is implied which
means all is visible.
double Time
Defines the point in time for which the geometry is defined. This may
lead to varied results for animated objects. This value is defined in the
range [0.0 .. n[, negative values are not allowed. If not given, a value of
0.0 is implied.

Parameter aViewParameters
2D View-specific parameter set, same as in getDecomposition.
