Hello,

Read Xvbf as Xvfb (virtual framebuffer X server).
Sorry for the error.

:>
:>
:> Hello,
:>
:> I developed a few sample JSP custom tags which does image manipulation.
:>
:> Please download the image.war file which has an index.jsp which
:> displays all
:> the examples.
:> Download it from http://www.mullassery.com/downloads/image.war (1.7MB
:> approx. This includes the JAI jar files which are required. So as you all
:> know just put it in the "webapps" folder and start Tomcat).
:> The index page explains all the tags and examples.
:>
:> If one of you has an access to a good web server with JSP support (and
:> X-Windows/ Xvbf), please add it there and send us a link so that everyone
:> can directly see the examples page without downloading.
:>
:> Only the base image tag example works without X-Windows/Xvbf support.
:>
:>
:> Please remember this is just an example for discussion purposes and not
:> final code.
:> Currently I have added:-
:> 	<image> -- Parent tag of all image tags which loads, scales
:> and outputs in
:> the required format (GIF/JPEG/PNG)
:> 	<text>  -- adds a colored string in the default font on the
:> image according
:> to the alignment specified.
:> 	<border>-- adds a border outside the image where the width,
:> height and
:> color of the border is specified.
:>
:> I have used JAI (Java Advanced Imaging) to load and manipulate images.
:> JAI does not need X-Windows (awt) to load images and hence the base image
:> tag works on servers without X-Windows too.
:> However since I need the Graphics object for the rest of the tags,
:> X-Windows/ xvbf is required.
:>
:> We need to finalize on:-
:> 	Design
:> 	Use of PJA/Xvbf/X-Windows
:>
:> More on these tags later..
:> Please take a look and comment.
