Method Details

doDraw

public void doDraw(SvgDrawContext context)

Description copied from class: AbstractSvgNodeRenderer

Draws this element to a canvas-like object maintained in the context.

Specified by:

doDraw in class AbstractSvgNodeRenderer

Parameters:

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

getObjectBoundingBox

public Rectangle getObjectBoundingBox(SvgDrawContext context)

Description copied from interface: ISvgNodeRenderer

Calculates the current object bounding box.

Specified by:

getObjectBoundingBox in interface ISvgNodeRenderer

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

canElementFill

protected boolean canElementFill()

Description copied from class: AbstractSvgNodeRenderer

Method to see if a certain renderer can use fill.

Overrides:

canElementFill in class AbstractSvgNodeRenderer

Returns:

true if the renderer can use fill

getAttribute

float getAttribute(Map<String,String> attributes,
 String key)

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

Returns:

deep copy of this renderer

drawMarker

public void drawMarker(SvgDrawContext context,
 MarkerVertexType markerVertexType)

Description copied from interface: IMarkerCapable

Draws a marker in the specified context. The marker is drawn on the vertices defined according to the given marker type.

Specified by:

drawMarker in interface IMarkerCapable

Parameters:

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

markerVertexType - type of marker that determine on which vertices of the given element marker should be drawn

getAutoOrientAngle

public double getAutoOrientAngle(MarkerSvgNodeRenderer marker,
 boolean reverse)

Description copied from interface: IMarkerCapable

Calculates marker orientation angle if orient attribute is set to auto

Specified by:

getAutoOrientAngle in interface IMarkerCapable

Parameters:

marker - marker for which the rotation angle should be calculated

reverse - indicates that the resulting angle should be rotated 180 degrees

Returns:

marker orientation angle so that its positive x-axis is pointing in the direction of the path at the point it is placed

setParameters

private boolean setParameters(SvgDrawContext context)
