Constructor Detail

ShapeRenderer

public ShapeRenderer()

Creates a new ShapeRenderer with default base size of 10 pixels.

ShapeRenderer

public ShapeRenderer(int size)

Creates a new ShapeRenderer with given base size.

Parameters:

size - the base size in pixels

Method Detail

setBaseSize

public void setBaseSize(int size)

Sets the base size, in pixels, for shapes drawn by this renderer. The base size is the width and height value used when a VisualItem's size value is 1. The base size is scaled by the item's size value to arrive at the final scale used for rendering.

Parameters:

size - the base size in pixels

getBaseSize

public int getBaseSize()

Returns the base size, in pixels, for shapes drawn by this renderer.

Returns:

the base size in pixels

getRawShape

protected java.awt.Shape getRawShape(VisualItem item)

Description copied from class: AbstractShapeRenderer

Return a non-transformed shape for the visual representation of the item. Subclasses must implement this method.

Specified by:

getRawShape in class AbstractShapeRenderer

Parameters:

item - the VisualItem being drawn

Returns:

the "raw", untransformed shape.
