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.
