Managing offscreen images is impossible on UNIX machines
with no awt and/or X11 libs installed
at all, neither with PJA Toolkit as a replacement of Java 1.2 to
1.4 default AWT Toolkit,
nor with Java 1.4 default AWT Toolkit and java.awt.headless System
property set to true (please read this
message on PJA
Toolkit forum or the
Reply 12 on Java Technology forum for more information).
Nevertheless, PJA architecture allows you to create offscreen
images even on this kind of very restrictive system and draw into these images,
but only if you explicitly use com.eteks.awt.PJAImage and/or com.eteks.awt.PJAGraphics classes.
Some developers are interested by this feature even if in this case their
program depends explicitly on PJA Toolkit : it allows them to develop
graphics servlets or programs that will always always work whatever the end
user installed
on his machine. For example, you will be able to generate images on
a basic
Debian Linux distribution with Sun's JDK and Tomcat.
eTeks may decide to improve
PJA library for this kind of use and would like to get your opinion
about the future features in PJA Toolkit you desire the most. You may also
