Height of the sign in LEDs. The Border width in pixels. Color of the border when there is an active URL-link. Width of the space character in LEDs. Sizes can be 1,2,3, or 4.
Drawing is slightly slower but the result is more pleasing.
The applet's static width and height need to be matched to the dynamic wth and ht parameters in order for the sign to just fill the space in the document. This was a pain in earlier versions of LED Sign. With V3.1, the applet will print a message to the Java Console if there is a mispatch between these two sets of dimensions. The way to use this feature is to set the wth and ht to the dimensions you want for the sign. Now run the applet and look at the Java console output.
