Quake Tools
Each one of them is a single C file that should compile OOTB on any platform.
E.g. gcc -o pal2tga pal2tga.c
Their usage is pretty consistent - you supply the input files.
PAL2TGA wants a .lmp palette file, TGA2PAL wants a .tga image file - and so on.
They are all released under the MIT License. Binaries for Win32 are outdated but usable.
TrueVision Targa seems to be one of the saner image formats. The GIMP handles those fine.
Most advanced editors do...
PAL2TGA
Converts a Quake palette file into a 24bit TrueVision Targa file for direct editing.
pal2tga.c
TGA2PAL
Imports a 16x16 24bit Targa (like one generated by PAL2TGA) and converts it into a Quake palette file.
tga2pal.c
LMP2TGA
Convert Quake graphic lump files (.lmp) into a TrueVision Targa for editing.
Allows use of a custom palette.lmp file for non-standard modifications/games.
Note: colormap.lmp and palette.lmp are no typical graphic lumps - opening them
will most likely result in an error when validating the header.
lmp2tga.c
TGA2LMP
Converts a 24bit Targa into a Quake graphic lump file.
Allows use of a custom palette.lmp file for non-standard modifications/games.
tga2lmp.c
TGA2SPR
Converts 24bit Targas into a Quake sprite lump file.
Allows use of a custom palette.lmp file for non-standard modifications/games, like the others...
Arguably the most complex one, README instructions required!
tga2spr.c

/*
This tool converts 24-bit, uncompressed Targa files into Quake sprites.
You just have to give it a few more infos.
Syntax:
.\tga2spr sprite.qc
In which "sprite.qc" is a plaintext file containing a number of commands.
Notice that you can also pop in a palette.lmp from whatever mod you're
targetting into the same directory. By default it uses Quake's palette.
It will not add any dithering.
If you want any dithering during palettization, use an external tool.
The GNU Image Manipulation Program provides that feature.
Just remember to export it as a 24-bit image again.
================
LIST OF COMMANDS
================
output [STRING]
Specifies the output sprite. E.g. flame.spr
identifer [CHARS]
Specifies the magic number. In case you use some modded engine that allows
that. Default: IDSP
version [INT]
Specifies the sprite version. Default 1.
type [INT]
Specifies the sprite type. Used for orientation. Default is 0.
0: parallel upright
1: facing upright
2: parallel
3: oriented
4: parallel oriented
radius [FLOAT]
Default is 1.0. Not sure if even used.
synctype [INT]
Default is 0. If not 0, animation starts at random offsets.
maxwidth [INT]
Used for the visible bounding box. Use the width value of the largest frame.
maxheight [INT]
Used for the visible bounding box. Use the height value of the largest
frame.
reserved [INT]
Unused in default Quake. Kurok uses this I believe. Default is 0.
frame [TGANAME] [OFFSET X] [OFFSET Y]
Single frame. Loads for [TGANAME] (e.g. flame1.tga) and specifies an offset
in INT form (X and Y)
anim [TGATITLE] [NUMFRAMES] [OFFSET X] [OFFSET Y] [...FPS*FRAME]
An entire animationgroup. TGATITLE is the Targa name without extension.
E.g. if you specify "flame" it will look for flame_1.tga, flame_2.tga and so
on.
You then specify the number of frames and offset of that group and a
frame-delay for each frame in the animation. Play with it.
Keep in mind that some engines ignore variable framerates in sprites.
You don't have to use ALL available parameters.
For example you have a sprite that's 64x64 in size.
3 Targa images, One is static (wow.tga) and the two others are meant to be an
animation sequence (face_1.tga, face_2.tga).
Then you'd have this:
output test.spr
maxwidth 64
maxheight 64
frame wow 0 0
anim face 2 0 0 8 5
For every frame inside the anim parameter, you should append a FPS number.
Otherwise a value of 1 is assumed for each frame.
In the above exmaple, face_1 will skip to the next at 8 fps, while the
other will do so at 5 fps.
Despite the somewhat in-complete implementation of the SPR spec in most engines.
I hope this tool will be of use to somebody.
Use the program as-is. If you notice any glaring problems feel free
to mail me (marco at icculus dot org) and we can talk about them.
Due to the way it's written, it doesn't allocate much memory, it streams it from
the input right to the output. This is by design. This way you can export large
sprites (gigabytes worth) even on DOS. Use at your own risk.

This tool converts 24-bit, uncompressed Targa files into Quake sprites.
You just have to give it a few more infos.
Syntax:
.\tga2spr sprite.qc
In which "sprite.qc" is a plaintext file containing a number of commands.
Notice that you can also pop in a palette.lmp from whatever mod you're
targetting into the same directory. By default it uses Quake's palette.
It will not add any dithering.
If you want any dithering during palettization, use an external tool.
The GNU Image Manipulation Program provides that feature.
Just remember to export it as a 24-bit image again.
================
LIST OF COMMANDS
================
output [STRING]
Specifies the output sprite. E.g. flame.spr
identifer [CHARS]
Specifies the magic number. In case you use some modded engine that allows
that. Default: IDSP
version [INT]
Specifies the sprite version. Default 1.
type [INT]
Specifies the sprite type. Used for orientation. Default is 0.
0: parallel upright
1: facing upright
2: parallel
3: oriented
4: parallel oriented
radius [FLOAT]
Default is 1.0. Not sure if even used.
synctype [INT]
Default is 0. If not 0, animation starts at random offsets.
maxwidth [INT]
Used for the visible bounding box. Use the width value of the largest frame.
maxheight [INT]
Used for the visible bounding box. Use the height value of the largest
frame.
reserved [INT]
Unused in default Quake. Kurok uses this I believe. Default is 0.
frame [TGANAME] [OFFSET X] [OFFSET Y]
Single frame. Loads for [TGANAME] (e.g. flame1.tga) and specifies an offset
in INT form (X and Y)
anim [TGATITLE] [NUMFRAMES] [OFFSET X] [OFFSET Y] [...FPS*FRAME]
An entire animationgroup. TGATITLE is the Targa name without extension.
E.g. if you specify "flame" it will look for flame_1.tga, flame_2.tga and so
on.
You then specify the number of frames and offset of that group and a
frame-delay for each frame in the animation. Play with it.
Keep in mind that some engines ignore variable framerates in sprites.
You don't have to use ALL available parameters.
For example you have a sprite that's 64x64 in size.
3 Targa images, One is static (wow.tga) and the two others are meant to be an
animation sequence (face_1.tga, face_2.tga).
Then you'd have this:
output test.spr
maxwidth 64
maxheight 64
frame wow 0 0
anim face 2 0 0 8 5
For every frame inside the anim parameter, you should append a FPS number.
Otherwise a value of 1 is assumed for each frame.
In the above exmaple, face_1 will skip to the next at 8 fps, while the
other will do so at 5 fps.
Despite the somewhat in-complete implementation of the SPR spec in most engines.
I hope this tool will be of use to somebody.
Use the program as-is. If you notice any glaring problems feel free
to mail me (marco at icculus dot org) and we can talk about them.
Due to the way it's written, it doesn't allocate much memory, it streams it from
the input right to the output. This is by design. This way you can export large
sprites (gigabytes worth) even on DOS. Use at your own risk.
