I've put together a REXPaint-specific guide containg tips and techniques for getting the most out of REXPaint, whether for art or roguelike development.

I've also written an article in which I explain the process behind Cogmind's ASCII art style.

For advanced users, the extensive manual included with REXPaint contains plenty of useful information, including a description of all features as well as how to extend REXPaint with additional palettes, fonts, and libraries.

Download the linked text file and drop it in the data/palettes directory. Alternatively, download all the palettes in a single package (uncompress to data/palettes dir).

User palettes: Provided by individual REXPaint users based on their own work found in the gallery, or popular palettes I've collected.

Legacy system palettes: Provided by AtariAge members nitrofurano and barnieg. Amstrad monochrome by DiamondTroller.

As of 1.70, REXPaint can automatically import .gpl (GIMP) files, for example from lowspec.com

Download the image itself, drop it in the data/fonts directory, and list the font in _config.xt, a text file. Alternatively, download all the fonts in a single package (uncompress to data/fonts dir, though you'll still need to update your own _config.txt).

User fonts: Provided by individual REXPaint users based on their own work.

Legacy system fonts: Provided by AtariAge members nitrofurano and barnieg.

Miscellaneous fonts: Ceefax fonts provided by Polyducks. "Taken from the analogue tv's teletext chip specifications. The top row of characters are custom control characters and should not be visible on output. In order: Polyducks' logo, large font above, end large font, flash, end flash, hide, end hide, misc, end misc." PETSCII provided by iLKke.
