public class IconPrimitive

extends RGO

implements javax.swing.Icon

General Swing-style icons as rectangular graphical objects.

Objects from this class contain an icon object; that is, an object that implements the Swing Icon interface. While this class can be used directly to display arbitrary icons, it is likely to be more useful to extend the class. For one thing, icons as such are defined in fixed, pixel units, so re-scaling of the drawn object is not directly supported, making icons less flexible than most graphical objects.

Description copied from class: GraphicalObject

draw the object in the rectangular region rr, using scales sx and sy.

Overrides:

draw in class GraphicalObject

Following copied from interface: org.omegahat.Graphics.Primitives.GraphicalComponentInt

Parameters:

rr - the parents RectRegion in normalized device coordinates (NDC).

sx - the parent's horizontal scale for transforming between arbitrary units.

sy - the parent's vertical scale for transforming between arbitrary units.

origin - the parent's origin position.
