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 MetaFuleRenderer. + + 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! + + +****************************************************************************************************/ + +void VclMetafileProcessor2D::processBasePrimitive2D(const primitive2d::BasePrimitive2D& rCandidate) +{ + switch (rCandidate.getPrimitive2DID()) + { + case PRIMITIVE2D_ID_WRONGSPELLPRIMITIVE2D: + { + // directdraw of wrong spell primitive + // Ignore for VclMetafileProcessor2D, this is for printing and MetaFile recording only + break; + } + case PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D: + { + processGraphicPrimitive2D( + static_cast<const primitive2d::GraphicPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_CONTROLPRIMITIVE2D: + { + processControlPrimitive2D( + static_cast<const primitive2d::ControlPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTHIERARCHYFIELDPRIMITIVE2D: + { + processTextHierarchyFieldPrimitive2D( + static_cast<const primitive2d::TextHierarchyFieldPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTHIERARCHYLINEPRIMITIVE2D: + { + processTextHierarchyLinePrimitive2D( + static_cast<const primitive2d::TextHierarchyLinePrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTHIERARCHYBULLETPRIMITIVE2D: + { + processTextHierarchyBulletPrimitive2D( + static_cast<const primitive2d::TextHierarchyBulletPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTHIERARCHYPARAGRAPHPRIMITIVE2D: + { + processTextHierarchyParagraphPrimitive2D( + static_cast<const primitive2d::TextHierarchyParagraphPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTHIERARCHYBLOCKPRIMITIVE2D: + { + processTextHierarchyBlockPrimitive2D( + static_cast<const primitive2d::TextHierarchyBlockPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_TEXTSIMPLEPORTIONPRIMITIVE2D: + case PRIMITIVE2D_ID_TEXTDECORATEDPORTIONPRIMITIVE2D: + { + // for supporting TEXT_ MetaFile actions there is more to do here; get the candidate + processTextSimplePortionPrimitive2D( + static_cast<const primitive2d::TextSimplePortionPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D: + { + processPolygonHairlinePrimitive2D( + static_cast<const primitive2d::PolygonHairlinePrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D: + { + processPolygonStrokePrimitive2D( + static_cast<const primitive2d::PolygonStrokePrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D: + { + processPolygonStrokeArrowPrimitive2D( + static_cast<const primitive2d::PolygonStrokeArrowPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_BITMAPPRIMITIVE2D: + { + // direct draw of transformed BitmapEx primitive; use default processing, but without + // former testing if graphic content is inside discrete local viewport; this is not + // setup for metafile targets (metafile renderer tries to render in logic coordinates, + // the mapping is kept to the OutputDevice for better Metafile recording) + RenderBitmapPrimitive2D(static_cast<const primitive2d::BitmapPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D: + { + processPolyPolygonGraphicPrimitive2D( + static_cast<const primitive2d::PolyPolygonGraphicPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D: + { + processPolyPolygonHatchPrimitive2D( + static_cast<const primitive2d::PolyPolygonHatchPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D: + { + processPolyPolygonGradientPrimitive2D( + static_cast<const primitive2d::PolyPolygonGradientPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D: + { + processPolyPolygonColorPrimitive2D( + static_cast<const primitive2d::PolyPolygonColorPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_MASKPRIMITIVE2D: + { + processMaskPrimitive2D(static_cast<const primitive2d::MaskPrimitive2D&>(rCandidate)); + break; + } + case PRIMITIVE2D_ID_MODIFIEDCOLORPRIMITIVE2D: + { + // modified color group.
