Method Details

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

isObjectBoundingBoxUnits

 protected boolean isObjectBoundingBoxUnits() 
            

Checks whether the gradient units values are on user space on use or object bounding box

Returns:

false if the 'gradientUnits' value of the gradient tag equals to 'userSpaceOnUse', otherwise true

getGradientTransform

 protected AffineTransform getGradientTransform() 
            

Evaluates the 'gradientTransform' transformations

Returns:

an AffineTransform object representing the specified gradient transformation

getChildStopRenderers

 protected List<StopSvgNodeRenderer> getChildStopRenderers() 
            

Construct a list of child stop renderers

Returns:

a list of StopSvgNodeRenderer elements that represents the child stop values

parseSpreadMethod

 protected GradientSpreadMethod parseSpreadMethod() 
            

Parses the gradient spread method

Returns:

the parsed GradientSpreadMethod specified in the gradient
