/** WallpaperBitmapPrimitive2D class
|
|
|
|
This is a specialized primtive for the Wallpaper definitions included in
|
|
VCL and Metafiles. The extraordinary about the bitmap definition part of
|
|
the Wallpaper is that it uses PIXEL size of the given Bitmap and not
|
|
the logic and/or discrete size derived by PrefMapMode/PrefSize methods.
|
|
To emulate this, a ViewTransformation dependent primitive is needed which
|
|
takes over the correct scaling(s).
|
|
|
|
Since a specialized primitive is needed anyways, i opted to also add the
|
|
layouting which is dependent from WallpaperStyle; thus it does not need
|
|
to be handled anywhere else in the future.
