The PXL tool provides the ability to write a C-like program to control the creation of its output image. The program executed by the PXL tool is written in a new language called PXL, the Pixel eXpression Language (pronounced “pixel”). The PXL language offers a rich set of features like conditionals, looping, and numerous built-in functions. The PXL tool offers users the ability to create new effects by writing a PXL language program. The PXL tool can be used to implement any point or gather operator, as it can read any pixel in its input images.

Another will be to write longer scripts to create customized effects that are not supplied by Composite, which will be shared by many users. Examples might include:
