Hi,

How can i access the screen pixels from within a Java program? I want
to locate small images on the screen drawn by another process
(shockwave player in IE). In order to do that I need access to the
pixels on the screen.

Use java.awt.Robot.createScreenCapture() to get a BufferedImage you
can analyze.

java.awt.Robot can do this (Java 1.3 or higher). Here's example code
on how to use it:
