/*
Support of MetaCommentActions in the VclMetafileProcessor2D
Found MetaCommentActions and how they are supported:
XGRAD_SEQ_BEGIN, XGRAD_SEQ_END:
Used inside OutputDevice::DrawGradient to mark the start and end of a MetaGradientEx action.
It is used in various exporters/importers to have direct access to the gradient before it
is rendered by VCL (and thus fragmented to polygon color actions and others). On that base, e.g.
the Metafile to SdrObject import creates it's gradient objects.
Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
map it back to the corresponding tools PolyPolygon and the Gradient and just call
OutputDevice::DrawGradient which creates the necessary compatible actions.
XPATHFILL_SEQ_BEGIN, XPATHFILL_SEQ_END:
Two producers, one is vcl/source/gdi/gdimtf.cxx, line 1273. There, it is transformed
inside GDIMetaFile::Rotate, nothing to take care of here.
The second producer is in graphics/svx/source/svdraw/impgrfll.cxx, line 374. This is used
with each incarnation of ImpGraphicFill when a metafile is recorded, fillstyle is not
XFILL_NONE and not completely transparent. It creates a SvtGraphicFill and streams it
to the comment action. A closing end token is created in the destructor.
Usages of ImpGraphicFill are in DoPaintObject-methods of SdrCircObj, SdrPathObj and
SdrRectObj.
The token users pick various actions from SvtGraphicFill, so it may need to be added for all kind
of filled objects, even simple colored polygons. It is added as extra information; the
Metafile actions between the two tokens are interpreted as output generated from those
fills. Thus, users have the choice to use the SvtGraphicFill info or the created output
actions.
Even for XFillTransparenceItem it is used, thus it may need to be supported in
UnifiedAlphaPrimitive2D, too, when interpreted as normally filled PolyPolygon.
Implemented for:
PRIMITIVE2D_ID_POLYPOLYGONBITMAPPRIMITIVE2D,
PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
and for PRIMITIVE2D_ID_UNIFIEDALPHAPRIMITIVE2D when detected unified alpha
To be done:
XPATHSTROKE_SEQ_BEGIN, XPATHSTROKE_SEQ_END:
Similar to pathfill, but using SvtGraphicStroke instead. It also has two producers where one
is also the GDIMetaFile::Rotate. Another user is MetaCommentAction::Move which modifies the
contained path accordingly.
The other one is SdrObject::ImpDrawLineGeometry. It's done when MetaFile is set at OutDev and
only when geometry is a single polygon (!). I see no reason for that; in the PS exporter this
would hinder to make use of PolyPolygon strokes. I will need to add support at:
PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D
PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D
PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D
This can be done hierarchical, too.
Okay, base implementation done based on those three primitives.
