public class ClipPathSvgNodeRenderer extends AbstractBranchSvgNodeRenderer
This renderer represents a collection of elements (simple shapes and paths). The elements are not drawn visibly, but the union of their shapes will be used to only show the parts of the drawn objects that fall within the clipping path. In PDF, the clipping path operators use the intersection of all its elements, not the union (as in SVG); thus, we need to draw the clipped elements multiple times if the clipping path consists of multiple elements.

createDeepCopy
public ISvgNodeRenderer createDeepCopy()
Description copied from interface:ISvgNodeRenderer
Creates a deep copy of this renderer, including it's subtree of children- Specified by:
createDeepCopy
in interfaceISvgNodeRenderer
- Specified by:
createDeepCopy
in classAbstractBranchSvgNodeRenderer
- Returns:
- deep copy of this renderer
-
getObjectBoundingBox
public Rectangle getObjectBoundingBox(SvgDrawContext context)
Description copied from interface:ISvgNodeRenderer
Calculates the current object bounding box.- Parameters:
context
- the current context, for instance it contains current viewport and available font data- Returns:
- the
Rectangle
representing the current object's bounding box, or null if bounding box is undefined
-
preDraw
void preDraw(SvgDrawContext context)

- Parameters:
context
- the svg draw context
-
doDraw
protected void doDraw(SvgDrawContext context)
Description copied from class:AbstractBranchSvgNodeRenderer

doDraw
in classAbstractBranchSvgNodeRenderer
- Parameters:
context
- the object that knows the place to draw this element and maintains its state
