File: demoform.php
Role: Example script
Content type: text/plain
Description: A form for the various options of this class and then display image.
Class: ATextImage
Layout and render text on images
Author: By
Last change: 1) The textimage is now displayed at the top of the page followed
by the form. This occurs after the submit button is clicked.

2) When the form is redisplayed the submited information is displayed.

3) There is now a drop down select box to choose the font. It looks in
the directory for any .ttf files and puts them in the select box.

4) In order to display the image on the same page as the form, another
script, formimage.php, is used for this purpose.
