ACFTools is a utility for manipulating X-Plane flight simulator aircraft and weapon models without using its Plane Maker. It can decode both Apple and Intel ACF/WPN formats into plain text files with a syntax similar to C, which can be edited and then re-converted into binary data. It is able to extract almost complete 3D models of aircraft (fuselage, floats, tanks, wings, stabs, propellers, engines) and write it in AC3D modeler format. Edited 3D parts can then be merged into plain text and consequently converted into binary ACF files.
WP Clipart is an attempt to make a useful clip art package of public domain images for use in word processors. It includes an optional cross-platform viewer/editor written with Python/GTK. The collection contains primarily non-transparent PNG images, mid-tones expanded and large shadow areas minimized (to prevent blocking-up) for inkjet print quality. It is suitable for documents as well as Web graphics, but also has business application. Its primary focus is for educational use (pictures of all US presidents, all country flags alphabetically listed, all US states, historical figures, a sign language alphabet, and a large American history section.)
