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! 738 739 740 741 ****************************************************************************************************/ 742 743 void VclMetafileProcessor2D::processBasePrimitive2D(const primitive2d::BasePrimitive2D& rCandidate) 744 { 745 switch(rCandidate.getPrimitive2DID()) 746 { 747 case PRIMITIVE2D_ID_WRONGSPELLPRIMITIVE2D : 748 { 749 // directdraw of wrong spell primitive 750 // Ignore for VclMetafileProcessor2D, this is for printing and MetaFile recording only 751 break; 752 } 753 case PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D : 754 { 755 const primitive2d::GraphicPrimitive2D& rGraphicPrimitive = static_cast< const primitive2d::GraphicPrimitive2D& >(rCandidate); 756 bool bUsingPDFExtOutDevData(false); 757 basegfx::B2DVector aTranslate, aScale; 758 static bool bSuppressPDFExtOutDevDataSupport(false); 759 760 if(mpPDFExtOutDevData && !bSuppressPDFExtOutDevDataSupport) 761 { 762 // emulate data handling from UnoControlPDFExportContact, original see 763 // svtools/source/graphic/grfmgr.cxx 764 const Graphic& rGraphic = rGraphicPrimitive.getGraphicObject().GetGraphic(); 765 766 if(rGraphic.IsLink()) 767 { 768 const GraphicAttr& rAttr = rGraphicPrimitive.getGraphicAttr(); 769 770 if(!rAttr.IsSpecialDrawMode() && !rAttr.IsAdjusted()) 771 { 772 const basegfx::B2DHomMatrix& rTransform = rGraphicPrimitive.getTransform(); 773 double fRotate, fShearX; 774 rTransform.decompose(aScale, aTranslate, fRotate, fShearX); 775 776 if( basegfx::fTools::equalZero( fRotate ) && ( aScale.getX() > 0.0 ) && ( aScale.getY() > 0.0 ) ) 777 { 778 bUsingPDFExtOutDevData = true; 779 mpPDFExtOutDevData->BeginGroup(); 780 } 781 } 782 } 783 } 784 785 // process recursively and add MetaFile comment 786 process(rGraphicPrimitive.get2DDecomposition(getViewInformation2D())); 787 788 if(bUsingPDFExtOutDevData) 789 { 790 // emulate data handling from UnoControlPDFExportContact, original see 791 // svtools/source/graphic/grfmgr.cxx 792 const basegfx::B2DRange aCurrentRange( 793 aTranslate.getX(), aTranslate.getY(), 794 aTranslate.getX() + aScale.getX(), aTranslate.getY() + aScale.getY()); 795 const Rectangle aCurrentRect( 796 sal_Int32(floor(aCurrentRange.getMinX())), sal_Int32(floor(aCurrentRange.getMinY())), 797 sal_Int32(ceil(aCurrentRange.getMaxX())), sal_Int32(ceil(aCurrentRange.getMaxY()))); 798 const GraphicAttr& rAttr = rGraphicPrimitive.getGraphicAttr(); 799 800 // #123295# As described below this is the expanded, uncropped region 801 // and needs to be given in any case, especially when no cropping it is 802 // equal to the current rect.
