It decomposes to a TransformPrimitive2D embedded 42 into a ModifiedColorPrimitive2D. 43 44 It's for primtive usage convenience, so that not everyone has 45 to implement the generic shadow construction by himself. 46 47 The same geometry as sequence of primitives is used as geometry and 48 as shadow. Since these are RefCounted Uno-Api objects, no extra objects 49 are needed for the shadow itself; all the local decompositions of the 50 original geometry can be reused from the renderer for shadow visualisation. 51 */ 52 class DRAWINGLAYER_DLLPUBLIC ShadowPrimitive2D : public GroupPrimitive2D 53 { 54 private: 55 /// the shadow transformation, normally just an offset 56 basegfx::B2DHomMatrix maShadowTransform; 57 58 /// the shadow color to which all geometry is to be forced 59 basegfx::BColor maShadowColor; 60 61 public: 62 /// constructor 63 ShadowPrimitive2D( 64 const basegfx::B2DHomMatrix& rShadowTransform, 65 const basegfx::BColor& rShadowColor, 66 const Primitive2DSequence& rChildren); 67 68 /// data read access getShadowTransform() const69 const basegfx::B2DHomMatrix& getShadowTransform() const { return maShadowTransform; } getShadowColor() const70 const basegfx::BColor& getShadowColor() const { return maShadowColor; } 71 72 /// compare operator 73 virtual bool operator==(const BasePrimitive2D& rPrimitive) const; 74 75 /// get range 76 virtual basegfx::B2DRange getB2DRange(const geometry::ViewInformation2D& rViewInformation) const; 77 78 /// create decomposition 79 virtual Primitive2DSequence get2DDecomposition(const geometry::ViewInformation2D& rViewInformation) const; 80 81 /// provide unique ID 82 DeclPrimitrive2DIDBlock() 83 }; 84 } // end of namespace primitive2d 85 } // end of namespace drawinglayer 86 87 ////////////////////////////////////////////////////////////////////////////// 88 89 #endif //INCLUDED_DRAWINGLAYER_PRIMITIVE2D_SHADOWPRIMITIVE2D_HXX 90 91 ////////////////////////////////////////////////////////////////////////////// 92 // eof 93
