At least XIeeeDoubleBitmap should be among them (why 43 else would you use this template, then?). Base class must have 44 an Base( const Mutex& ) constructor (like the 45 WeakComponentImplHelperN templates have). 46 47 @tpl CanvasHelper 48 Canvas helper implementation for the backend in question 49 50 @tpl Mutex 51 Lock strategy to use. Defaults to using the 52 OBaseMutex-provided lock. Every time one of the methods is 53 entered, an object of type Mutex is created with m_aMutex as 54 the sole parameter, and destroyed again when the method scope 55 is left. 56 57 @tpl UnambiguousBase 58 Optional unambiguous base class for XInterface of Base. It's 59 sometimes necessary to specify this parameter, e.g. if Base 60 derives from multiple UNO interface (were each provides its 61 own version of XInterface, making the conversion ambiguous) 62 63 @see CanvasBase for further contractual requirements towards 64 the CanvasHelper type, and some examples. 65 */ 66 template< class Base, 67 class CanvasHelper, 68 class Mutex=::osl::MutexGuard, 69 class UnambiguousBase=::com::sun::star::uno::XInterface > class DoubleBitmapBase : 70 public BitmapCanvasBase< Base, CanvasHelper, Mutex, UnambiguousBase > 71 { 72 public: 73 typedef BitmapCanvasBase< Base, CanvasHelper, Mutex, UnambiguousBase > BaseType; 74 75 // XIeeeDoubleBitmap getData(::com::sun::star::rendering::FloatingPointBitmapLayout & bitmapLayout,const::com::sun::star::geometry::IntegerRectangle2D & rect)76 virtual ::com::sun::star::uno::Sequence< double > SAL_CALL getData( ::com::sun::star::rendering::FloatingPointBitmapLayout& bitmapLayout, 77 const ::com::sun::star::geometry::IntegerRectangle2D& rect ) throw (::com::sun::star::lang::IndexOutOfBoundsException, 78 ::com::sun::star::rendering::VolatileContentDestroyedException, 79 ::com::sun::star::uno::RuntimeException) 80 { 81 verifyInput(rect, this); 82 verifyIndexRange(rect, getSize() ); 83 84 typename BaseType::MutexType aGuard( BaseType::m_aMutex ); 85 86 return BaseType::maCanvasHelper.getData( bitmapLayout, 87 rect ); 88 } 89 setData(const::com::sun::star::uno::Sequence<double> & data,const::com::sun::star::rendering::FloatingPointBitmapLayout & bitmapLayout,const::com::sun::star::geometry::IntegerRectangle2D & rect)90 virtual void SAL_CALL setData( const ::com::sun::star::uno::Sequence< double >& data, 91 const ::com::sun::star::rendering::FloatingPointBitmapLayout& bitmapLayout, 92 const ::com::sun::star::geometry::IntegerRectangle2D& rect ) throw (::com::sun::star::lang::IllegalArgumentException, 93 ::com::sun::star::lang::IndexOutOfBoundsException, 94 ::com::sun::star::uno::RuntimeException) 95 { 96 verifyInput(bitmapLayout, rect, this); 97 verifyIndexRange(rect, getSize() ); 98 99 typename BaseType::MutexType aGuard( BaseType::m_aMutex ); 100 101 BaseType::mbSurfaceDirty = true; 102 BaseType::maCanvasHelper.modifying(); 103 104 BaseType::maCanvasHelper.setData( data, bitmapLayout, rect ); 105 } 106 setPixel(const::com::sun::star::uno::Sequence<double> & color,const::com::sun::star::rendering::FloatingPointBitmapLayout & bitmapLayout,const::com::sun::star::geometry::IntegerPoint2D & pos)107 virtual void SAL_CALL setPixel( const ::com::sun::star::uno::Sequence< double >& color, 108 const ::com::sun::star::rendering::FloatingPointBitmapLayout& bitmapLayout, 109 const ::com::sun::star::geometry::IntegerPoint2D& pos ) throw (::com::sun::star::lang::IllegalArgumentException, 110 ::com::sun::star::lang::IndexOutOfBoundsException, 111 ::com::sun::star::uno::RuntimeException) 112 { 113 verifyInput(bitmapLayout, pos, this); 114 verifyIndexRange(pos, getSize() ); 115 116 typename BaseType::MutexType aGuard( BaseType::m_aMutex ); 117 118 BaseType::mbSurfaceDirty = true; 119 BaseType::maCanvasHelper.modifying(); 120 121 BaseType::maCanvasHelper.setPixel( color, bitmapLayout, pos ); 122 } 123 getPixel(::com::sun::star::rendering::FloatingPointBitmapLayout & bitmapLayout,const::com::sun::star::geometry::IntegerPoint2D & pos)124 virtual ::com::sun::star::uno::Sequence< double > SAL_CALL getPixel( ::com::sun::star::rendering::FloatingPointBitmapLayout& bitmapLayout, 125 const ::com::sun::star::geometry::IntegerPoint2D& pos ) throw (::com::sun::star::lang::IndexOutOfBoundsException, 126 ::com::sun::star::rendering::VolatileContentDestroyedException, 127 ::com::sun::star::uno::RuntimeException) 128 { 129 verifyInput(pos, this); 130 verifyIndexRange(pos, getSize() ); 131 132 typename BaseType::MutexType aGuard( BaseType::m_aMutex ); 133 134 return BaseType::maCanvasHelper.getPixel( bitmapLayout, 135 pos ); 136 } 137 getMemoryLayout()138 virtual ::com::sun::star::rendering::FloatingPointBitmapLayout SAL_CALL getMemoryLayout( ) throw (::com::sun::star::uno::RuntimeException) 139 { 140 typename BaseType::MutexType aGuard( BaseType::m_aMutex ); 141 142 return BaseType::maCanvasHelper.getMemoryLayout(); 143 } 144 }; 145 } 146 147 #endif /* INCLUDED_CANVAS_DOUBLEBITMAPBASE_HXX */ 148
