Class ClipPathSvgNodeRenderer

java.lang.Object

All Implemented Interfaces:

IBranchSvgNodeRenderer, ISvgNodeRenderer

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.

Method Details

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 interface ISvgNodeRenderer

Specified by:

createDeepCopy in class AbstractBranchSvgNodeRenderer

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)

Description copied from class: AbstractSvgNodeRenderer

Operations to perform before drawing an element. This includes setting stroke color and width, fill color.

Overrides:

preDraw in class AbstractSvgNodeRenderer

Parameters:

context - the svg draw context

doDraw

protected void doDraw(SvgDrawContext context)

Description copied from class: AbstractBranchSvgNodeRenderer

Method that will set properties to be inherited by this branch renderer's children and will iterate over all children in order to draw them.

Overrides:

doDraw in class AbstractBranchSvgNodeRenderer

Parameters:

context - the object that knows the place to draw this element and maintains its state

drawClippedRenderer

public void drawClippedRenderer(SvgDrawContext context)

Draw the clipped renderer.

Parameters:

context - the context on which clipped renderer will be drawn

setClippedRenderer

public void setClippedRenderer(AbstractSvgNodeRenderer clippedRenderer)

Sets the clipped renderer.

Parameters:

clippedRenderer - the clipped renderer

isHidden

protected boolean isHidden()

Description copied from class: AbstractSvgNodeRenderer

Check if this renderer should draw the element based on its attributes (e.g. visibility/display)

Overrides:

isHidden in class AbstractSvgNodeRenderer

Returns:

true if element won't be drawn, false otherwise
