GRFCodec — A tool to convert a GRF file into graphics files and meta data, and vice versa.
grfcodec [-sv] [-d | -e] [options] GRF‐file [Directory] <GRF‐File> denotes the .GRF file you want to work on, e.g. TRG1.GRF <Directory> is where the individual sprites should be saved. If omitted, they will default to a subdirectory called sprites/.
-? Display the help message. -e Encode a GRF file. The GRF‐file to pass is the file where to encode to. The source of the GRF‐file, i.e. the .nfo, will be looked for in sprites/GRF‐file.nfo. All graphics files will be searched for relative from the location of the GRF‐file. -d Decode a GRF file. The GRF‐file to pass is the file to decode. The result will be in sprites/GRF‐file.nfo and sprites/GRF‐file.png. -s Silences the progress output in interactive mode -v Display the version. Options for decoding: -w num Write spritesheets files with the given width (default 800, minimum 16) -h num Split spritesheets when they reach this height (default no limit, minimum 16) -b num Organize sprites in boxes of this size (default 16) -o ssf Sets the format of generated spritesheets. See -o ? for a list. -p pal Use this palette instead of the default. See -p ? for a list. -t Disable decoding of plain text characters as strings. -x Disable production of unquoted escape sequences. -xx Disable production of both quoted and unquoted escape sequences. This has the side effect of producing a version 6 .nfo, instead of a version 7 .nfo. -X List sprite numbers in the image file in hex. Options for encoding: -c Crop extraneous transparent blue from real sprites -u Save uncompressed data (probably not a good idea) -q Suppress warning messages -g num Create a GRF file with the given container version. Valid versions are 1 and 2, where the latter allows bigger sprites, larger sounds, and multiple zoom levels and bit depths for the sprites. -n Try both compression algorithms and use the most efficient. This might cause trouble when loading the NewGRF in TTDPatch. Options for both encoding and decoding: -m num Apply colour translation to all sprites except character‐glyphs. -M num Apply colour translation to all sprites. If both of these are specified, only the last is obeyed. -m ? or -M ? for a list of colour translations.
