NAME

     GRFDiff -- A tool to create a binary GRF diff from to GRFs.

SYNOPSIS

     grfdiff [-hnxyv] [-l numbers] [-o GRF-File] Original-GRF-file New-GRF-file

	     Compare the two GRF files and produce a GRD file containing only the sprites from the second file that are different from the first
	     file.

	     GRFDiff makes a .GRD file with the same basename as the new GRF file.

OPTIONS

     -h 	 Display the help message.

     -l numbers  Save the sprites with these numbers in the .GRD instead of finding the modified sprites.  With this option, the first GRF file
		 can be omitted.

		 Format of the numbers: <from1>[-<to1>][,<from2>[-<to2>]]...  e.g.  1-5,8,20-31 (must be increasing numbers).

     -n 	 Only show a list of modified sprites, don't make a .GRF file.

     -x 	 Make a self-extracting (.EXE) file instead of a .GRD.

     -y 	 Answer 'y' to all questions.

     -v 	 Display the version.

     You can specify several sets of GRF files along with their -l options by separating them with a double-dash `--'.	The result will be written
     to a single .GRD file.  Only -l is valid after the first set.

GRFCodec(1)						    BSD General Commands Manual 					       GRFCodec(1)

NAME

     GRFCodec -- A tool to convert a GRF file into graphics files and meta data, and vice versa.

SYNOPSIS

     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/.

OPTIONS

     -? 	 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.
