98 \brief Provides 2D context for shapes on a Canvas item. -

99 -

100 The Context2D object can be created by \c Canvas item's \c getContext() -

101 method: -

102 \code -

103 Canvas { -

104 id:canvas -

105 onPaint:{ -

106 var ctx = canvas.getContext('2d'); -

107 //... -

108 } -

109 } -

110 \endcode -

111 The Context2D API implements the same \l -

112 {http://www.w3.org/TR/2dcontext}{W3C Canvas 2D Context API standard} with -

113 some enhanced features. -

114 -

115 The Context2D API provides the rendering \b{context} which defines the -

116 methods and attributes needed to draw on the \c Canvas item. The following -

117 assigns the canvas rendering context to a \c{context} variable: -

118 \code -

119 var context = mycanvas.getContext("2d") -

120 \endcode -

121 -

122 The Context2D API renders the canvas as a coordinate system whose origin -

123 (0,0) is at the top left corner, as shown in the figure below. Coordinates -

124 increase along the \c{x} axis from left to right and along the \c{y} axis -

125 from top to bottom of the canvas. -
