Class ImageBevelBorder

java.lang.Object
  org.jhotdraw.draw.action.ImageBevelBorder

All Implemented Interfaces:

javax.swing.border.Border

public class ImageBevelBorder
extends java.lang.Object
implements javax.swing.border.Border

Draws a filled bevel border using an image and insets. The image must consist of a bevel and a fill area.

The insets and the size of the image are used do determine which parts of the image shall be used to draw the corners and edges of the bevel as well the fill area.

For example, if you provide an image of size 10,10 and a insets of size 2, 2, 4, 4, then the corners of the border are made up of top left: 2,2, top right: 2,4, bottom left: 2,4, bottom right: 4,4 rectangle of the image. The inner area of the image is used to fill the inner area.
