- GIF_TEXT: A Graphical Text Generator
-
- GIF_TEXT ver 1.2f is an OS/2 program that converts text strings into.GIF images.
- Using one of the several included "alphabyte" or "complete" fonts,
- it's easy to make attractive banners, headers, and other messages.
-
- GIF_TEXT can be invoked in several ways:
- * as a CGI-BIN script running on an OS/2 web server
- * as an "addon" for the SRE-http (formerly known as SRE-Filter) web server
- * as a stand-alone program
-
- Some of GIF_TEXT's features include:
- * dynamically generate time and date using one of several REXX formats.
- -- you can use GIF_TEXT as a graphical digital-clock for your web pages.
- * backgrounds can be added to your message
- * addition of new "alphabytes" is easy -- and with a little bit
- of effort, you can even use true-type fonts.
- * messages can be sized to specific height and width
- * messages can contain several lines of text, and
- can contain embedded font changes
- * character specific scaling
- * color slides, color gradients, or foreground images can be used to
- color the text; with probability and original-color-value based
- transformation rules.
- * using included HTML FORM documents, it's easy to create images
- -- including "buttons with text"
- * a FORM based HTML front-end is included
- * when used with SRE-http, a "download pieces as they become available"
- mode can be used to speed up percieved throughput
