Graphical Transformation is a "legacy" transformation algorithm that is built on top of Chameleon's table architecture. Chameleon has the capability of acting as an interface engine. The technique is to have two configurations, which are used to represent the input and output configurations of the engine. Each configuration has the same Table Grammar in common, making it possible to map from one format to the other.

Python scripts can be used to manipulate field and/or segment data. You can also declare constants such as the production mode "P", sending facility, sending application and other constants that do not change.

	Did You Know? Scripted Transformation is the recommended transformation algorithm and is considered the ideal long-term solution for performing transformation functions in applications built with Chameleon, or in Iguana. It is based almost completely on Python scripting and is considered a much more flexible option than graphical transformation. For more information, see Scripted Transformation.

This section of the manual explores how the mappings are defined and tested using a short example:
