GRFCodec — A tool to convert a GRF file into graphics files and meta data, and vice versa.
|grfcodec|| [-sv] [-d | -e] [options] |
<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.
- Encode a GRF file. The
GRF‐fileto 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.
- Decode a GRF file. The
GRF‐fileto pass is the file to decode. The result will be in
- Silences the progress output in interactive mode
- Display the version.
Options for decoding:
- Write spritesheets files with the given width (default 800, minimum 16)
- Split spritesheets when they reach this height (default no limit, minimum 16)
- Organize sprites in boxes of this size (default 16)
- Sets the format of generated spritesheets. See -o ? for a list.
- Use this palette instead of the default. See -p ? for a list.
- Disable decoding of plain text characters as strings.
- Disable production of unquoted escape sequences.
- 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.
- List sprite numbers in the image file in hex.
Options for encoding:
- Crop extraneous transparent blue from real sprites
- Save uncompressed data (probably not a good idea)
- Suppress warning messages
- 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.
- 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:
- Apply colour translation to all sprites except character‐glyphs.
- 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.
