The extraordinary about the bitmap definition part of 42 the Wallpaper is that it uses PIXEL size of the given Bitmap and not 43 the logic and/or discrete size derived by PrefMapMode/PrefSize methods. 44 To emulate this, a ViewTransformation dependent primitive is needed which 45 takes over the correct scaling(s). 46 47 Since a specialized primitive is needed anyways, i opted to also add the 48 layouting which is dependent from WallpaperStyle; thus it does not need 49 to be handled anywhere else in the future. 50 */ 51 class DRAWINGLAYER_DLLPUBLIC WallpaperBitmapPrimitive2D : public ViewTransformationDependentPrimitive2D 52 { 53 private: 54 basegfx::B2DRange maObjectRange; 55 BitmapEx maBitmapEx; 56 WallpaperStyle meWallpaperStyle; 57 58 protected: 59 /// create local decomposition 60 virtual Primitive2DSequence create2DDecomposition(const geometry::ViewInformation2D& rViewInformation) const; 61 62 public: 63 /// constructor 64 WallpaperBitmapPrimitive2D( 65 const basegfx::B2DRange& rObjectRange, 66 const BitmapEx& rBitmapEx, 67 WallpaperStyle eWallpaperStyle); 68 69 /// data read access getLocalObjectRange() const70 const basegfx::B2DRange& getLocalObjectRange() const { return maObjectRange; } getBitmapEx() const71 const BitmapEx& getBitmapEx() const { return maBitmapEx ; } getWallpaperStyle() const72 WallpaperStyle getWallpaperStyle() const { return meWallpaperStyle; } 73 74 /// compare operator 75 virtual bool operator==(const BasePrimitive2D& rPrimitive) const; 76 77 /// get B2Drange 78 virtual basegfx::B2DRange getB2DRange(const geometry::ViewInformation2D& rViewInformation) const; 79 80 /// provide unique ID 81 DeclPrimitrive2DIDBlock() 82 }; 83 } // end of namespace primitive2d 84 } // end of namespace drawinglayer 85 86 ////////////////////////////////////////////////////////////////////////////// 87 88 #endif // INCLUDED_DRAWINGLAYER_PRIMITIVE2D_WALLPAPERPRIMITIVE2D_HXX 89 90 ////////////////////////////////////////////////////////////////////////////// 91 // eof 92
