For Developers

Download D.I.Y. kit and unpack it (it is in a tar-gz format). This includes all the bitmap files, and some programs to combine them.
Alternatively, you can download the latest CVS repository by:
% cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/rltiles co rltiles

"rltiles/dctile.exe" is a program to generate tileset. If you are using LINUX, type as below:
% cc tool/dctile.c tool/bm.c -o dctile

Feed it a configuration file (dc-2d.txt for Dungeon Crawl and nh-2d.txt for NetHack), then the program combines bitmap files into a large BMP file which is used by the games. On Windows, Drag and Drop the txt file to dctile.exe. On LINUX, run "dctile nh-2d.txt", etc.
If you want to change some tile, browse "map.html" generated by dctile.exe. You will find which bmp file correspond to the tile you want to change. Edit the corresponding tile, or alternatively, create a new tile and edit the txt file, and change the entry name of the tile to your new bmp file (.bmp suffix is not needed).
To create a new tile, start from "rltiles/blank.bmp" and use the 256 color palette in it.
If you are a developer of some Roguelike game and like to generate a tileset for your game, write down a new configuration file and feed it to dctile.exe.

How to generate player paperdoll tile

% cc tool/dcpl.c tool/bm.c -o dcpl
