Nested Sets DB Tree is a class that can be used to manipulate nested sets of database table records that form an hierarchical tree. It provides the means to initialize the record tree, insert record nodes in specific tree positions, retrieve node and parent records, change the position of nodes, and delete record nodes. It uses ANSI SQL statements and the ADODB library to make it work with many database types. Transactions are supported through the ADODB class. The library supports the gettext multilanguage interface.

AKVIS Chameleon is an efficient tool for photo collage creation. It eliminates the tedium of selecting an object with a complicated shape for pasting into a new background. The software has three modes: montage, chameleon, and blend. Montage mode fades the irrelevant parts of an object into the background. Chameleon mode adjusts the inserted object to the target image's color range and smooths the object's borders. Blend mode both adjusts the color range and smooths the object's borders and also makes the object semi-transparent.
