All Implemented Interfaces:

java.awt.print.Printable

public class CicUtilsEx

extends CicUtils

implements java.awt.print.Printable

This is the general utiliy class for Cic's InkTools package in its extended version.

Note: this class requires the JRE 1.3 and above, due to the PCL related Methods. Use CicUtils for JRE 1.1 compatibility.

It covers two areas: helper functions for what is called HTTP Tunneling and helper functions to convert signatures into images.

A HTTP form can communicate with a servlet through GET and POST requests. Java's 'java.net' package provides classes that can be utilized to establish a direct HTTP communication between an applet and a servlet, a technique known as HTTP Tunneling. If the URL of the servlet is known, an applet can simple call the functions 'httpGet' or 'httpPost' to send requests and receive the servlet response.

Often it is reqired to display ink data or signatures as an image rather than redisplay it in an InkControl. The 'createJpegImage' will create a Jpeg image from a signature, as does 'createGifImage' and 'createPclImage'.
