Modifier and Type	Method	Description
(package private) float	checkRadius(float radius, float distance)	a radius must be positive, and cannot be more than half the distance in the dimension it is for.

protected void	doDraw(SvgDrawContext context)	Draws this element to a canvas-like object maintained in the context.
(package private) float	findCircularRadius(float rx, float ry, float width, float height)	In case of a circular radius, the calculation in checkRadius(float, float) isn't enough: the radius cannot be more than half of the smallest dimension.

Constructor Details

RectangleSvgNodeRenderer

public RectangleSvgNodeRenderer()

Constructs a RectangleSvgNodeRenderer.

Method Details

doDraw

protected 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.

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

setParameters

private void setParameters(SvgDrawContext context)

checkRadius

float checkRadius(float radius,
 float distance)

a radius must be positive, and cannot be more than half the distance in the dimension it is for. e.g. rx <= width / 2

findCircularRadius

float findCircularRadius(float rx,
 float ry,
 float width,
 float height)

In case of a circular radius, the calculation in checkRadius(float, float) isn't enough: the radius cannot be more than half of the smallest dimension. This method assumes that checkRadius(float, float) has already run, and it is silently assumed (though not necessary for this method) that either rx or ry is zero.

createDeepCopy

public ISvgNodeRenderer createDeepCopy()

Description copied from interface: ISvgNodeRenderer

Creates a deep copy of this renderer, including it's subtree of children

Returns:

deep copy of this renderer
