582 :
583 : Support of MetaCommentActions in the VclMetafileProcessor2D
584 : Found MetaCommentActions and how they are supported:
585 :
586 : XGRAD_SEQ_BEGIN, XGRAD_SEQ_END:
587 :
588 : Used inside OutputDevice::DrawGradient to mark the start and end of a MetaGradientEx action.
589 : It is used in various exporters/importers to have direct access to the gradient before it
590 : is rendered by VCL (and thus fragmented to polygon color actions and others). On that base, e.g.
591 : the Metafile to SdrObject import creates it's gradient objects.
592 : Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
593 : map it back to the corresponding tools PolyPolygon and the Gradient and just call
594 : OutputDevice::DrawGradient which creates the necessary compatible actions.
595 :
596 : XPATHFILL_SEQ_BEGIN, XPATHFILL_SEQ_END:
597 :
598 : Two producers, one is vcl/source/gdi/gdimtf.cxx, line 1273. There, it is transformed
599 : inside GDIMetaFile::Rotate, nothing to take care of here.
600 : The second producer is in graphics/svx/source/svdraw/impgrfll.cxx, line 374. This is used
601 : with each incarnation of Imp_GraphicFill when a metafile is recorded, fillstyle is not
602 : XFILL_NONE and not completely transparent. It creates a SvtGraphicFill and streams it
603 : to the comment action. A closing end token is created in the destructor.
604 : Usages of Imp_GraphicFill are in Do_Paint_Object-methods of SdrCircObj, SdrPathObj and
605 : SdrRectObj.
606 : The token users pick various actions from SvtGraphicFill, so it may need to be added for all kind
607 : of filled objects, even simple colored polygons. It is added as extra information; the
608 : Metafile actions between the two tokens are interpreted as output generated from those
609 : fills. Thus, users have the choice to use the SvtGraphicFill info or the created output
610 : actions.
611 : Even for XFillTransparenceItem it is used, thus it may need to be supported in
612 : UnifiedTransparencePrimitive2D, too, when interpreted as normally filled PolyPolygon.
613 : Implemented for:
614 : PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D,
615 : PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
616 : PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
617 : PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
618 : and for PRIMITIVE2D_ID_UNIFIEDTRANSPARENCEPRIMITIVE2D when detected unified transparence
619 :
620 : XPATHSTROKE_SEQ_BEGIN, XPATHSTROKE_SEQ_END:
621 :
622 : Similar to pathfill, but using SvtGraphicStroke instead. It also has two producers where one
623 : is also the GDIMetaFile::Rotate. Another user is MetaCommentAction::Move which modifies the
624 : contained path accordingly.
625 : The other one is SdrObject::Imp_DrawLineGeometry. It's done when MetaFile is set at OutDev and
626 : only when geometry is a single polygon (!). I see no reason for that; in the PS exporter this
627 : would hinder to make use of PolyPolygon strokes. I will need to add support at:
628 : PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D
629 : PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D
630 : PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D
631 : This can be done hierarchical, too.
632 : Okay, base implementation done based on those three primitives.
633 :
634 : FIELD_SEQ_BEGIN, FIELD_SEQ_END
635 :
636 : Used from slideshow for URLs, created from diverse SvxField implementations inside
637 : createBeginComment()/createEndComment(). createBeginComment() is used from editeng\impedit3.cxx
638 : inside ImpEditEngine::Paint.
639 : Created TextHierarchyFieldPrimitive2D and added needed infos there; it is an group primitive and wraps
640 : text primitives (but is not limited to that). It contains the field type if special actions for the
641 : support of FIELD_SEQ_BEGIN/END are needed; this is the case for Page and URL fields. If more is
642 : needed, it may be supported there.
643 : FIELD_SEQ_BEGIN;PageField
644 : FIELD_SEQ_END
645 : Okay, these are now completely supported by TextHierarchyFieldPrimitive2D. URL works, too.
646 :
647 : XTEXT
648 :
649 : XTEXT_EOC(i) end of character
650 : XTEXT_EOW(i) end of word
651 : XTEXT_EOS(i) end of sentence
652 :
653 : this three are with index and are created with the help of a i18n::XBreakIterator in
654 : ImplDrawWithComments. Simplifying, moving out text painting, reworking to create some
655 : data structure for holding those TEXT infos.
656 : Supported directly by TextSimplePortionPrimitive2D with adding a Locale to the basic text
657 : primitive. In the MetaFileRenderer, the creation is now done (see below). This has the advantage
658 : that this creations do not need to be done for all paints all the time. This would be
659 : expensive since the BreakIterator and it's usage is expensive and for each paint also the
660 : whole character stops would need to be created.
661 : Created only for TextDecoratedPortionPrimitive2D due to XTEXT_EOL and XTEXT_EOP (see below)
662 :
663 : XTEXT_EOL() end of line
664 : XTEXT_EOP() end of paragraph
665 :
666 : First try with boolean marks at TextDecoratedPortionPrimitive2D did not work too well,
667 : i decided to solve it with structure. I added the TextHierarchyPrimitives for this,
668 : namely:
669 : - TextHierarchyLinePrimitive2D: Encapsulates single line
670 : - TextHierarchyParagraphPrimitive2D: Encapsulates single paragraph
671 : - TextHierarchyBlockPrimitive2D: encapsulates object texts (only one ATM)
672 : Those are now supported in hierarchy. This means the MetaFile renderer will support them
673 : by using them, reculrively using their content and adding MetaFile comments as needed.
674 : This also means that when another text layouter will be used it will be necessary to
675 : create/support the same HierarchyPrimitives to support users.
676 : To transport the information using this hierarchy is best suited to all future needs;
677 : the slideshow will be able to profit from it directly when using primitives; all other
678 : renderers not interested in the text structure will just ignore the encapsulations.
679 :
680 : XTEXT_PAINTSHAPE_BEGIN, XTEXT_PAINTSHAPE_END
681 : Supported now by the TextHierarchyBlockPrimitive2D.
682 :
683 : EPSReplacementGraphic:
684 : Only used in goodies\source\filter.vcl\ieps\ieps.cxx and svx\source\xml\xmlgrhlp.cxx to
685 : hold the original EPS which was imported in the same MetaFile as first 2 entries. Only
686 : used to export the original again (if exists).
687 : Not necessary to support with MetaFuleRenderer.
688 :
689 : XTEXT_SCROLLRECT, XTEXT_PAINTRECT
690 : Currently used to get extra MetaFile infos using GraphicExporter which again uses
691 : SdrTextObj::GetTextScrollMetaFileAndRectangle(). ATM works with primitives since
692 : the rectangle data is added directly by the GraphicsExporter as comment. Does not need
693 : to be adapted at once.
694 : When adapting later, the only user - the diashow - should directly use the provided
695 : Anination infos in the appropriate primitives (e.g. AnimatedSwitchPrimitive2D)
696 :
697 : PRNSPOOL_TRANSPARENTBITMAP_BEGIN, PRNSPOOL_TRANSPARENTBITMAP_END
698 : VCL usage when printing PL -> THB. Okay, THB confirms that it is only used as
699 : a fix (hack) while VCL printing. It is needed to not downscale a bitmap which
700 : was explicitly created for the printer already again to some default maximum
701 : bitmap sizes.
702 : Nothing to do here for the primitive renderer.
703 :
704 : Support for vcl::PDFExtOutDevData:
705 : PL knows that SJ did that stuff, it's used to hold a pointer to PDFExtOutDevData at
706 : the OutDev. When set, some extra data is written there. Trying simple PDF export and
707 : watching if i get those infos.
708 : Well, a PDF export does not use e.g. ImpEditEngine::Paint since the PdfFilter uses
709 : the SdXImpressDocument::render and thus uses the VclMetafileProcessor2D. I will check
710 : if i get a PDFExtOutDevData at the target output device.
711 : Indeed, i get one. Checking what all may be done when that extra-device-info is there.
712 :
713 : All in all i have to talk to SJ. I will need to emulate some of those actions, but
714 : i need to discuss which ones.
715 : In the future, all those infos would be taken from the primitive sequence anyways,
716 : thus these extensions would potentially be temporary, too.
717 : Discussed with SJ, added the necessary support and tested it. Details follow.
718 :
719 : - In ImpEditEngine::Paint, paragraph infos and URL stuff is added.
720 : Added in primitive MetaFile renderer.
721 : Checking URL: Indeed, current version exports it, but it is missing in primitive
722 : CWS version. Adding support.
723 : Okay, URLs work. Checked, Done.
724 :
725 : - UnoControlPDFExportContact is only created when PDFExtOutDevData is used at the
726 : target and uno control data is created in UnoControlPDFExportContact::do_PaintObject.
727 : This may be added in primitive MetaFile renderer.
728 : Adding support...
729 : OOps, the necessary helper stuff is in svx/source/form/formpdxexport.cxx in namespace
730 : svxform. Have to talk to FS if this has to be like that. Especially since
731 : ::vcl::PDFWriter::AnyWidget is filled out, which is already part of vcl.
732 : Wrote an eMail to FS, he is on vacation currently. I see no reason why not to move
733 : that stuff to somewhere else, maybe tools or svtools ?!? We will see...
734 : Moved to toolkit, so i have to link against it. I tried VCL first, but it did
735 : not work since VCLUnoHelper::CreateFont is unresolved in VCL (!). Other then the name
736 : may imply, it is defined in toolkit (!). Since toolkit is linked against VCL itself,
737 : the lowest move,ment plave is toolkit.
738 : Checked form control export, it works well. Done.
739 :
740 : - In goodies, in GraphicObject::Draw, when the used Graphic is linked, infos are
741 : generated. I will need to check what happens here with primitives.
742 : To support, use of GraphicPrimitive2D (PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D) may be needed.
743 : Added support, but feature is broken in main version, so i cannot test at all.
744 : Writing a bug to CL (or SJ) and seeing what happens (#i80380#).
745 : SJ took a look and we got it working. Tested VCL MetaFile Renderer based export,
746 : as intended, the original file is exported. Works, Done.
747 :
748 :
749 :
750 :
751 : To be done:
752 :
753 : - Maybe there are more places to take care of for vcl::PDFExtOutDevData!
