It's geometry is defined 42 by MetaFileTransform. The content (defined by MetaFile) will be scaled 43 to the geometric definiton by using PrefMapMode and PrefSize of the 44 Metafile. 45 46 It has shown that this not always guarantees that all Metafile content 47 is inside the geometric definition, but this primitive defines that this 48 is the case to allow a getB2DRange implementation. If it cannot be 49 guaranteed that the Metafile is inside the geometric definition, it should 50 be embedded to a MaskPrimitive2D. 51 52 This primitive has no decomposition yet, so when not supported by a renderer, 53 it will not be visualized. 54 55 In the future, a decomposition implementation would be appreciated and would 56 have many advantages; Metafile would no longer have to be rendered by 57 sub-systems and a standard way for converting Metafiles would exist. 58 */ 59 class DRAWINGLAYER_DLLPUBLIC MetafilePrimitive2D : public BufferedDecompositionPrimitive2D 60 { 61 private: 62 /// the geometry definition 63 basegfx::B2DHomMatrix maMetaFileTransform; 64 65 /// the content definition 66 GDIMetaFile maMetaFile; 67 68 protected: 69 /// local decomposition. 70 virtual Primitive2DSequence create2DDecomposition(const geometry::ViewInformation2D& rViewInformation) const; 71 public: 72 /// constructor 73 MetafilePrimitive2D( 74 const basegfx::B2DHomMatrix& rMetaFileTransform, 75 const GDIMetaFile& rMetaFile); 76 77 /// data read access getTransform() const78 const basegfx::B2DHomMatrix& getTransform() const { return maMetaFileTransform; } getMetaFile() const79 const GDIMetaFile& getMetaFile() const { return maMetaFile; } 80 81 /// compare operator 82 virtual bool operator==(const BasePrimitive2D& rPrimitive) const; 83 84 /// get range 85 virtual basegfx::B2DRange getB2DRange(const geometry::ViewInformation2D& rViewInformation) const; 86 87 /// provide unique ID 88 DeclPrimitrive2DIDBlock() 89 }; 90 } // end of namespace primitive2d 91 } // end of namespace drawinglayer 92 93 ////////////////////////////////////////////////////////////////////////////// 94 95 #endif //INCLUDED_DRAWINGLAYER_PRIMITIVE2D_METAFILEPRIMITIVE2D_HXX 96 97 ////////////////////////////////////////////////////////////////////////////// 98 // eof 99
