- * @property string $encoding
- * Encoding of the SVG XML document
- * @property float $assumedNumericCharacterWidth
- * Assumed percentual average width of chars in numeric strings with
- * the used font.
- * @property float $assumedTextCharacterWidth
- * Assumed percentual average width of chars in non numeric strings
- * with the used font.
- * @property string $strokeLineCap
- * This specifies the shape to be used at the end of open subpaths
- * when they are stroked.
- * @property string $strokeLineJoin
- * This specifies the shape to be used at the edges of paths.
- * @property string $shapeRendering
- * "The creator of SVG content might want to provide a hint to the
- * implementation about what tradeoffs to make as it renders vector
- * graphics elements such as 'path' elements and basic shapes such as
- * circles and rectangles."
- * @property string $colorRendering
- * "The creator of SVG content might want to provide a hint to the
- * implementation about how to make speed vs. quality tradeoffs as it
- * performs color interpolation and compositing. The
- * 'color-rendering' property provides a hint to the SVG user agent
- * about how to optimize its color interpolation and compositing
- * operations."
- * @property string $textRendering
- * "The creator of SVG content might want to provide a hint to the
- * implementation about what tradeoffs to make as it renders text."
- * @property mixed $templateDocument
- * Use existing SVG document as template to insert graph into. If
- * insertIntoGroup is not set, a new group will be inserted in the
- * svg root node.
- * @property mixed $insertIntoGroup
- * ID of a SVG group node to insert the graph. Only works with a
- * custom template document.
- * @property ezcGraphCoordinate $graphOffset
- * Offset of the graph in the svg.
- * @property string $idPrefix
- * Prefix used for the ids in SVG documents.
- * @property string $linkCursor
- * CSS value for cursor property used for linked SVG elements
