+/***********************************************************************************************
+
+ 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 its gradient objects.
+ Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
+ map it back to the corresponding tools 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 Imp_GraphicFill 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 Imp_GraphicFill are in Do_Paint_Object-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
+ UnifiedTransparencePrimitive2D, too, when interpreted as normally filled PolyPolygon.
+ Implemented for:
+ PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D,
+ PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
+ PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
+ PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
+ and for PRIMITIVE2D_ID_UNIFIEDTRANSPARENCEPRIMITIVE2D when detected unified transparence
+
+ 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::Imp_DrawLineGeometry. 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 tools::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.
+
+ FIELD_SEQ_BEGIN, FIELD_SEQ_END
+
+ Used from slideshow for URLs, created from diverse SvxField implementations inside
+ createBeginComment()/createEndComment(). createBeginComment() is used from editeng\impedit3.cxx
+ inside ImpEditEngine::Paint.
+ Created TextHierarchyFieldPrimitive2D and added needed infos there; it is a group primitive and wraps
+ text primitives (but is not limited to that). It contains the field type if special actions for the
+ support of FIELD_SEQ_BEGIN/END are needed; this is the case for Page and URL fields. If more is
+ needed, it may be supported there.
+ FIELD_SEQ_BEGIN;PageField
+ FIELD_SEQ_END
+ Okay, these are now completely supported by TextHierarchyFieldPrimitive2D. URL works, too.
+
+ XTEXT
+
+ XTEXT_EOC(i) end of character
+ XTEXT_EOW(i) end of word
+ XTEXT_EOS(i) end of sentence
+
+ this three are with index and are created with the help of an i18n::XBreakIterator in
+ ImplDrawWithComments. Simplifying, moving out text painting, reworking to create some
+ data structure for holding those TEXT infos.
+ Supported directly by TextSimplePortionPrimitive2D with adding a Locale to the basic text
+ primitive. In the MetaFileRenderer, the creation is now done (see below). This has the advantage
+ that this creations do not need to be done for all paints all the time. This would be
+ expensive since the BreakIterator and it's usage is expensive and for each paint also the
+ whole character stops would need to be created.
+ Created only for TextDecoratedPortionPrimitive2D due to XTEXT_EOL and XTEXT_EOP (see below)
+
+ XTEXT_EOL() end of line
+ XTEXT_EOP() end of paragraph
+
+ First try with boolean marks at TextDecoratedPortionPrimitive2D did not work too well,
+ i decided to solve it with structure. I added the TextHierarchyPrimitives for this,
+ namely:
+ - TextHierarchyLinePrimitive2D: Encapsulates single line
+ - TextHierarchyParagraphPrimitive2D: Encapsulates single paragraph
+ - TextHierarchyBlockPrimitive2D: encapsulates object texts (only one ATM)
+ Those are now supported in hierarchy. This means the MetaFile renderer will support them
+ by using them, recursively using their content and adding MetaFile comments as needed.
+ This also means that when another text layouter will be used it will be necessary to
+ create/support the same HierarchyPrimitives to support users.
+ To transport the information using this hierarchy is best suited to all future needs;
+ the slideshow will be able to profit from it directly when using primitives; all other
+ renderers not interested in the text structure will just ignore the encapsulations.
+
+ XTEXT_PAINTSHAPE_BEGIN, XTEXT_PAINTSHAPE_END
+ Supported now by the TextHierarchyBlockPrimitive2D.
+
+ EPSReplacementGraphic:
+ Only used in goodies\source\filter.vcl\ieps\ieps.cxx and svx\source\xml\xmlgrhlp.cxx to
+ hold the original EPS which was imported in the same MetaFile as first 2 entries. Only
+ used to export the original again (if exists).
+ Not necessary to support with MetaFileRenderer.
+
+ XTEXT_SCROLLRECT, XTEXT_PAINTRECT
+ Currently used to get extra MetaFile infos using GraphicExporter which again uses
+ SdrTextObj::GetTextScrollMetaFileAndRectangle(). ATM works with primitives since
+ the rectangle data is added directly by the GraphicsExporter as comment. Does not need
+ to be adapted at once.
+ When adapting later, the only user - the diashow - should directly use the provided
+ Animation infos in the appropriate primitives (e.g. AnimatedSwitchPrimitive2D)
+
+ PRNSPOOL_TRANSPARENTBITMAP_BEGIN, PRNSPOOL_TRANSPARENTBITMAP_END
+ VCL usage when printing PL -> THB. Okay, THB confirms that it is only used as
+ a fix (hack) while VCL printing. It is needed to not downscale a bitmap which
+ was explicitly created for the printer already again to some default maximum
+ bitmap sizes.
+ Nothing to do here for the primitive renderer.
+
+ Support for vcl::PDFExtOutDevData:
+ PL knows that SJ did that stuff, it's used to hold a pointer to PDFExtOutDevData at
+ the OutDev. When set, some extra data is written there. Trying simple PDF export and
+ watching if I get those infos.
+ Well, a PDF export does not use e.g. ImpEditEngine::Paint since the PdfFilter uses
+ the SdXImpressDocument::render and thus uses the VclMetafileProcessor2D. I will check
+ if I get a PDFExtOutDevData at the target output device.
+ Indeed, I get one. Checking what all may be done when that extra-device-info is there.
+
+ All in all I have to talk to SJ. I will need to emulate some of those actions, but
+ i need to discuss which ones.
+ In the future, all those infos would be taken from the primitive sequence anyways,
+ thus these extensions would potentially be temporary, too.
+ Discussed with SJ, added the necessary support and tested it. Details follow.
+
+ - In ImpEditEngine::Paint, paragraph infos and URL stuff is added.
+ Added in primitive MetaFile renderer.
+ Checking URL: Indeed, current version exports it, but it is missing in primitive
+ CWS version. Adding support.
+ Okay, URLs work. Checked, Done.
+
+ - UnoControlPDFExportContact is only created when PDFExtOutDevData is used at the
+ target and uno control data is created in UnoControlPDFExportContact::do_PaintObject.
+ This may be added in primitive MetaFile renderer.
+ Adding support...
+ OOps, the necessary helper stuff is in svx/source/form/formpdxexport.cxx in namespace
+ svxform. Have to talk to FS if this has to be like that. Especially since
+ vcl::PDFWriter::AnyWidget is filled out, which is already part of vcl.
+ Wrote an eMail to FS, he is on vacation currently. I see no reason why not to move
+ that stuff to somewhere else, maybe tools or svtools ?!? We will see...
+ Moved to toolkit, so I have to link against it. I tried VCL first, but it did
+ not work since VCLUnoHelper::CreateFont is unresolved in VCL (!). Other than the name
+ may imply, it is defined in toolkit (!). Since toolkit is linked against VCL itself,
+ the lowest movement plane is toolkit.
+ Checked form control export, it works well. Done.
+
+ - In goodies, in GraphicObject::Draw, when the used Graphic is linked, infos are
+ generated. I will need to check what happens here with primitives.
+ To support, use of GraphicPrimitive2D (PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D) may be needed.
+ Added support, but feature is broken in main version, so i cannot test at all.
+ Writing a bug to CL (or SJ) and seeing what happens (#i80380#).
+ SJ took a look and we got it working. Tested VCL MetaFile Renderer based export,
+ as intended, the original file is exported. Works, Done.
+
+
+ To be done:
+
+ - Maybe there are more places to take care of for vcl::PDFExtOutDevData!
