Detailed Description

MetafilePrimitive2D class.

This is the MetaFile representing primitive. It's geometry is defined by MetaFileTransform. The content (defined by MetaFile) will be scaled to the geometric definition by using PrefMapMode and PrefSize of the Metafile.

It has shown that this not always guarantees that all Metafile content is inside the geometric definition, but this primitive defines that this is the case to allow a getB2DRange implementation. If it cannot be guaranteed that the Metafile is inside the geometric definition, it should be embedded to a MaskPrimitive2D.

This primitive has no decomposition yet, so when not supported by a renderer, it will not be visualized.

In the future, a decomposition implementation would be appreciated and would have many advantages; Metafile would no longer have to be rendered by sub-systems and a standard way for converting Metafiles would exist.
