Constructor Details

MarkerSvgNodeRenderer

public MarkerSvgNodeRenderer()

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

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
