OverviewThis small package (less than 1000 lines of Java code) was developed to provide a small and simple package for rendering text into an image (bitmap). It was developed for Google App Engine ... [More] use where AWT and BufferedImage et al do not exist. This small utility can be used to render text on App Engine within the constraints of the JRE Class White List. This is derived from the "pbmtext" utility from NETpbm Copyright (C) 1991 by Jef Poskanzer. These are crude black-and-white bitmap fonts - no anti-aliasing. A small number of BDF fonts in fixed-sizes are bundled into the package: Courier, Lucida-Bold-Italic, Lucida-Medium, Lucida-Medium-Italic, LucidaBright-DemiBold, LucidaTypewriter, LucidaTypewriter-Bold, and a default serif font. The following code snippet demonstrates use of litetext: byte[] bmp_data = doRender("Render this text into a bitmap"); // bmp_data contains a BMP fileMore InformationUsageOverview - Basic Java Usage and Options AppEngine - Using litetext in App Engine Live Demo - running on Google App Engine [Less]

This project is an open source steganography tool that can be used to hide and extract text to/ from Bitmap images.

This small code is able to transparently load a large bitmap map by blocks and presentate it with HTML, CSS and JavaScript. By licensing under Apache Licence it allows you to modify the code and use ... [More] it on your webpage with your very own maps. Enjoy [Less]
