I need a Linux command-line tool that takes an array of word/weight pairs (from a text file), representing a tag cloud. The tool should then generate a visual tag cloud similar to those made by [url removed, login to view] and output to a PNG, JPG or GIF file. The cloud should support fonts and colour palettes specified in the text file. The layout should support tightly nested (but not touching) words, like Wordle -- text can not be placed purely with bounding boxes. It should also support text arrangements of horizontal, mostly horizontal, half and half, mostly vertical or vertical (see wordle for examples). Ideally I'd like this written in PHP so it can be included directly in my project, but any command-line tool that works on Linux will suffice. I'm happy to install any 3rd party tools required.
