566 
567             Support of MetaCommentActions in the VclMetafileProcessor2D
568             Found MetaCommentActions and how they are supported:
569 
570             XGRAD_SEQ_BEGIN, XGRAD_SEQ_END:
571 
572             Used inside OutputDevice::DrawGradient to mark the start and end of a MetaGradientEx action.
573             It is used in various exporters/importers to have direct access to the gradient before it
574             is rendered by VCL (and thus fragmented to polygon color actions and others). On that base, e.g.
575             the Metafile to SdrObject import creates it's gradient objects.
576             Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
577             map it back to the corresponding tools PolyPolygon and the Gradient and just call
578             OutputDevice::DrawGradient which creates the necessary compatible actions.
579 
580             XPATHFILL_SEQ_BEGIN, XPATHFILL_SEQ_END:
581 
582             Two producers, one is vcl/source/gdi/gdimtf.cxx, line 1273. There, it is transformed
583             inside GDIMetaFile::Rotate, nothing to take care of here.
584             The second producer is in graphics/svx/source/svdraw/impgrfll.cxx, line 374. This is used
585             with each incarnation of Imp_GraphicFill when a metafile is recorded, fillstyle is not
586             XFILL_NONE and not completely transparent. It creates a SvtGraphicFill and streams it
587             to the comment action. A closing end token is created in the destructor.
588             Usages of Imp_GraphicFill are in Do_Paint_Object-methods of SdrCircObj, SdrPathObj and
589             SdrRectObj.
590             The token users pick various actions from SvtGraphicFill, so it may need to be added for all kind
591             of filled objects, even simple colored polygons. It is added as extra information; the
592             Metafile actions between the two tokens are interpreted as output generated from those
593             fills. Thus, users have the choice to use the SvtGraphicFill info or the created output
594             actions.
595             Even for XFillTransparenceItem it is used, thus it may need to be supported in
596             UnifiedTransparencePrimitive2D, too, when interpreted as normally filled PolyPolygon.
597             Implemented for:
598                 PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D,
599                 PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
600                 PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
601                 PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
602                 and for PRIMITIVE2D_ID_UNIFIEDTRANSPARENCEPRIMITIVE2D when detected unified transparence
603 
604             XPATHSTROKE_SEQ_BEGIN, XPATHSTROKE_SEQ_END:
605 
606             Similar to pathfill, but using SvtGraphicStroke instead. It also has two producers where one
607             is also the GDIMetaFile::Rotate. Another user is MetaCommentAction::Move which modifies the
608             contained path accordingly.
609             The other one is SdrObject::Imp_DrawLineGeometry. It's done when MetaFile is set at OutDev and
610             only when geometry is a single polygon (!). I see no reason for that; in the PS exporter this
611             would hinder to make use of PolyPolygon strokes. I will need to add support at:
612                 PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D
613                 PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D
614                 PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D
615             This can be done hierarchical, too.
616             Okay, base implementation done based on those three primitives.
617 
618             FIELD_SEQ_BEGIN, FIELD_SEQ_END
619 
620             Used from slideshow for URLs, created from diverse SvxField implementations inside
621             createBeginComment()/createEndComment(). createBeginComment() is used from editeng\impedit3.cxx
622             inside ImpEditEngine::Paint.
623             Created TextHierarchyFieldPrimitive2D and added needed infos there; it is an group primitive and wraps
624             text primitives (but is not limited to that). It contains the field type if special actions for the
625             support of FIELD_SEQ_BEGIN/END are needed; this is the case for Page and URL fields. If more is
626             needed, it may be supported there.
627             FIELD_SEQ_BEGIN;PageField
628             FIELD_SEQ_END
629             Okay, these are now completely supported by TextHierarchyFieldPrimitive2D. URL works, too.
630 
631             XTEXT
632 
633             XTEXT_EOC(i) end of character
634             XTEXT_EOW(i) end of word
635             XTEXT_EOS(i) end of sentence
636 
637             this three are with index and are created with the help of a i18n::XBreakIterator in
638             ImplDrawWithComments. Simplifying, moving out text painting, reworking to create some
639             data structure for holding those TEXT infos.
640             Supported directly by TextSimplePortionPrimitive2D with adding a Locale to the basic text
641             primitive. In the MetaFileRenderer, the creation is now done (see below). This has the advantage
642             that this creations do not need to be done for all paints all the time. This would be
643             expensive since the BreakIterator and it's usage is expensive and for each paint also the
644             whole character stops would need to be created.
645             Created only for TextDecoratedPortionPrimitive2D due to XTEXT_EOL and XTEXT_EOP (see below)
646 
647             XTEXT_EOL() end of line
648             XTEXT_EOP() end of paragraph
649 
650             First try with boolean marks at TextDecoratedPortionPrimitive2D did not work too well,
651             i decided to solve it with structure. I added the TextHierarchyPrimitives for this,
652             namely:
653             - TextHierarchyLinePrimitive2D: Encapsulates single line
654             - TextHierarchyParagraphPrimitive2D: Encapsulates single paragraph
655             - TextHierarchyBlockPrimitive2D: encapsulates object texts (only one ATM)
656             Those are now supported in hierarchy. This means the MetaFile renderer will support them
657             by using them, reculrively using their content and adding MetaFile comments as needed.
658             This also means that when another text layouter will be used it will be necessary to
659             create/support the same HierarchyPrimitives to support users.
660             To transport the information using this hierarchy is best suited to all future needs;
661             the slideshow will be able to profit from it directly when using primitives; all other
662             renderers not interested in the text structure will just ignore the encapsulations.
663 
664             XTEXT_PAINTSHAPE_BEGIN, XTEXT_PAINTSHAPE_END
665             Supported now by the TextHierarchyBlockPrimitive2D.
666 
667             EPSReplacementGraphic:
668             Only used in goodies\source\filter.vcl\ieps\ieps.cxx and svx\source\xml\xmlgrhlp.cxx to
669             hold the original EPS which was imported in the same MetaFile as first 2 entries. Only
670             used to export the original again (if exists).
671             Not necessary to support with MetaFuleRenderer.
672 
673             XTEXT_SCROLLRECT, XTEXT_PAINTRECT
674             Currently used to get extra MetaFile infos using GraphicExporter which again uses
675             SdrTextObj::GetTextScrollMetaFileAndRectangle(). ATM works with primitives since
676             the rectangle data is added directly by the GraphicsExporter as comment. Does not need
677             to be adapted at once.
678             When adapting later, the only user - the diashow - should directly use the provided
679             Anination infos in the appropriate primitives (e.g. AnimatedSwitchPrimitive2D)
680 
681             PRNSPOOL_TRANSPARENTBITMAP_BEGIN, PRNSPOOL_TRANSPARENTBITMAP_END
682             VCL usage when printing PL -> THB. Okay, THB confirms that it is only used as
683             a fix (hack) while VCL printing. It is needed to not downscale a bitmap which
684             was explicitely created for the printer already again to some default maximum
685             bitmap sizes.
686             Nothing to do here for the primitive renderer.
687 
688             Support for vcl::PDFExtOutDevData:
689             PL knows that SJ did that stuff, it's used to hold a pointer to PDFExtOutDevData at
690             the OutDev. When set, some extra data is written there. Trying simple PDF export and
691             watching if i get those infos.
692             Well, a PDF export does not use e.g. ImpEditEngine::Paint since the PdfFilter uses
693             the SdXImpressDocument::render and thus uses the VclMetafileProcessor2D. I will check
694             if i get a PDFExtOutDevData at the target output device.
695             Indeed, i get one. Checking what all may be done when that extra-device-info is there.
696 
697             All in all i have to talk to SJ. I will need to emulate some of those actions, but
698             i need to discuss which ones.
699             In the future, all those infos would be taken from the primitive sequence anyways,
700             thus these extensions would potentially be temporary, too.
701             Discussed with SJ, added the necessary support and tested it. Details follow.
702 
703             - In ImpEditEngine::Paint, paragraph infos and URL stuff is added.
704               Added in primitive MetaFile renderer.
705               Checking URL: Indeed, current version exports it, but it is missing in primitive
706               CWS version. Adding support.
707               Okay, URLs work. Checked, Done.
708 
709             - UnoControlPDFExportContact is only created when PDFExtOutDevData is used at the
710               target and uno control data is created in UnoControlPDFExportContact::do_PaintObject.
711               This may be added in primitive MetaFile renderer.
712               Adding support...
713               OOps, the necessary helper stuff is in svx/source/form/formpdxexport.cxx in namespace
714               svxform. Have to talk to FS if this has to be like that. Especially since
715               ::vcl::PDFWriter::AnyWidget is filled out, which is already part of vcl.
716               Wrote an eMail to FS, he is on vacation currently. I see no reason why not to move
717               that stuff to somewhere else, maybe tools or svtools ?!? We will see...
718               Moved to toolkit, so i have to link against it. I tried VCL first, but it did
719               not work since VCLUnoHelper::CreateFont is unresolved in VCL (!). Other then the name
720               may imply, it is defined in toolkit (!). Since toolkit is linked against VCL itself,
721               the lowest move,ment plave is toolkit.
722               Checked form control export, it works well. Done.
723 
724             - In goodies, in GraphicObject::Draw, when the used Graphic is linked, infos are
725               generated. I will need to check what happens here with primitives.
726               To support, use of GraphicPrimitive2D (PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D) may be needed.
727               Added support, but feature is broken in main version, so i cannot test at all.
728               Writing a bug to CL (or SJ) and seeing what happens (#i80380#).
729               SJ took a look and we got it working. Tested VCL MetaFile Renderer based export,
730               as intended, the original file is exported. Works, Done.
731 
732 
733 
734 
735             To be done:
736 
737             - Maybe there are more places to take care of for vcl::PDFExtOutDevData!
