Methods Summary
public java.lang.String[][]getParameterInfo()
Give Parameter info to the AppletViewer, just for those writing HTML without hardcopy documentation :-)

		String info[][] = {
			{ "label",		"string",	"Text to display" },
			{ "fontname",	"name",		"Font to display it in" },
			{ "fontsize",	"10-30?",	"Size to display it at" },
		};
		return info;
public voidinit()
Called from the browser to set up. We want to throw various kinds of exceptions but the API predefines that we don't, so we limit ourselves to the ubiquitous IllegalArgumentException.


	                              	 
	   
		// System.out.println("In DropShadow init()");

		theLabel = getParameter("label");
		if (theLabel == null)
				throw new IllegalArgumentException("LABEL is REQUIRED");
		// Now handle font stuff.
		fontName = getParameter("fontname");
		if (fontName == null)
				throw new IllegalArgumentException("FONTNAME is REQUIRED");
		String s;
		if ((s = getParameter("fontsize")) != null)
			fontSize = Integer.parseInt(s);
		if (fontName != null || fontSize != 0) {
			theFont = new Font(fontName, Font.BOLD + Font.ITALIC, fontSize);
			System.out.println("Name " + fontName + ", font " + theFont);
		}
		if ((s = getParameter("offset")) != null)
			theOffset = Integer.parseInt(s);
		setBackground(Color.green);
		inittedOK = true;
public voidpaint(java.awt.Graphics g)
Paint method showing drop shadow effect

		if (!inittedOK)
			return;
		g.setFont(theFont);
		g.setColor(Color.black);
