...mostly done with a rewriting Clang plugin, with just some manual tweaking necessary to fix poor macro usage. Change-Id: I71fa20213e86be10de332ece0aa273239df7b61a

/** CropPrimitive2D class
|
|
|
|
Caution: Due to old constraints (old core definitions) the
|
|
crop distances describe how the uncropped content is defined
|
|
relative to the current object size. This means that maTransformation
|
|
describes the rurrent object size (the part of the object visible
|
|
with the crop applied). To get the original size and orientation
|
|
of the uncropped content it is necessary to calc back from the
|
|
current situation (maTransformation) using the crop values
|
|
to get to the uncropped original content.
|
|
|
|
Thus a transformation has to be calculated which will be applied
|
|
to the already exsisting content to get it to the uncropped state
|
|
ans then this is masked with the current state (mask polygon
|
|
created from unit polygon and maTransformation).
|
|
|
|
At least in this primitive the units of the crop values are
|
|
already in the local coordinate system; inthe core these distances
|
|
are defined relative to the object content size (PrefMapMode
|
|
and PrefSize of the content)...
|
|
|
|
Of course this is a primitive, so feel free to just ignore all that
|
|
stuff and use the automatically generated decomposition. Sigh.
