== The TXD Format ==
 
a TXD file is a Renderware texture dictionary.
 
 
 
TXD files have the same basic format as DFF files and consist of sections with different purpose.
 
See [http://www.chronetal.co.uk/gta/index.php?page=dff KCows dff documentation] for more infos.
 
Every section has a 12 byte section header, containing type, size and ver id.
 
Here are some version id's along with the renderware api version they are associated with and the gta game they're found in:
 
 
 
  File Tag  API version
 
  0x00000302 0x30200
 
  0x00000310 0x31000
 
  0x0800FFFF 0x32000 for GTA3,
 
  0x0C02FFFF 0x33002 for VC PS2 and
 
  0x1003FFFF 0x34003 for VC PC
 
  0x1400FFFF 0x35000
 
  0x1803FFFF 0x36003 for SA
 
  0x1c020001 0x37002
 
 
 
 
 
The (usual) txd format looks like this:
 
 
 
  (22) Texture Dictionary
 
  |
 
  +--> (1) Data ( Specific to the Texture Dictionary )
 
  |
 
  +-+ (21) Texture Native No. 1
 
  | |-+ (1) Data (all the texture information and the image itself)
 
  | |
 
  | +-- (3) Extension (always empty - size=0) --> MISSING
 
  |
 
  +-+ (21) Texture Native No. 2
 
  | |-- ... (same as above)
 
  |
 
  +-+ (21) Texture Native No. 3
 
  |-- ...
 
 
 
(The number in brackets stands for the section type - dword)
 
 
 
The break down for each section is as follows
 
 
 
===Texture Dictionary Data===
 
4 bytes nbrTextures
 
 
 
This section only contains the number of textures in this texture dictionary.
 
 
 
===Texture Native Data===
 
Size      Name
 
4 bytes  unknown
 
4 bytes  flags
 
32 bytes  name
 
32 bytes  alpha name
 
4 bytes  raster format
 
4 bytes  has alpha (why you need a whole 4 bytes for a flag is beyond me)
 
2 bytes  width
 
2 bytes  height
 
1 byte    bpp
 
1 byte    mipmaps
 
1 byte    rastertype
 
1 byte    dxt
 
4 bytes  raster size
 
followed by "raster size" of bytes for the actual raster image.
 
 
 
These are the raster formats:
 
 
DEFAULT    = 0x0000
 
FORMAT1555 = 0x0100
 
FORMAT565  = 0x0200
 
FORMAT4444 = 0x0300
 
FORMATLUM8 = 0x0400
 
FORMAT8888 = 0x0500
 
FORMAT888  = 0x0600
 
FORMAT16  = 0x0700
 
FORMAT24  = 0x0800
 
FORMAT32  = 0x0900
 
FORMAT555  = 0x0a00
 
FORMATAUTOMIPMAP = 0x1000
 
FORMATPAL8      = 0x2000
 
FORMATPAL4      = 0x4000
 
FORMATMIPMAP    = 0x8000
