+ Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
10
+
11
+ The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
12
+ packed custom format called FTEX. This file format uses file extensions FTC
13
+ and FTU.
14
+ * FTC files are compressed textures (using standard texture compression).
15
+ * FTU files are not compressed.
16
+ Texture File Format
17
+ The FTC and FTU texture files both use the same format. This
18
+ has the following structure:
19
+ {header}
20
+ {format_directory}
21
+ {data}
22
+ Where:
23
+ {header} = {
24
+ u32:magic,
25
+ u32:version,
26
+ u32:width,
27
+ u32:height,
28
+ u32:mipmap_count,
29
+ u32:format_count
30
+ }
31
+
32
+ * The "magic" number is "FTEX".
33
+ * "width" and "height" are the dimensions of the texture.
34
+ * "mipmap_count" is the number of mipmaps in the texture.
35
+ * "format_count" is the number of texture formats (different versions of the
36
+ same texture) in this file.
37
+
38
+ {format_directory} = format_count * { u32:format, u32:where }
39
+
40
+ The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
41
+ uncompressed textures.
42
+ The texture data for a format starts at the position "where" in the file.
43
+
44
+ Each set of texture data in the file has the following structure:
45
+ {data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
46
+ * "mipmap_size" is the number of bytes in that mip level. For compressed
47
+ textures this is the size of the texture data compressed with DXT1. For 24 bit
48
+ uncompressed textures, this is 3 * width * height. Following this are the image
49
+ bytes for that mipmap level.
50
+
51
+ Note: All data is stored in little-Endian (Intel) byte order.

57
+ Originally released under LGPL. Graciously donated to PIL in
58
+ March 2009, for distribution under the standard PIL license
59
+
60
+ The pyCMS.py module provides a "clean" interface between Python/PIL and
61
+ pyCMSdll, taking care of some of the more complex handling of the direct
62
+ pyCMSdll functions, as well as error-checking and making sure that all
63
+ relevant data is kept together.
64
+
65
+ While it is possible to call pyCMSdll functions directly, it's not highly
66
+ recommended.
67
+
68
+ Version History:
69
+
70
+ 1.0.0 pil Oct 2013 Port to LCMS 2.
71
+
72
+ 0.1.0 pil mod March 10, 2009
73
+
74
+ Renamed display profile to proof profile. The proof
75
+ profile is the profile of the device that is being
76
+ simulated, not the profile of the device which is
77
+ actually used to display/print the final simulation
78
+ (that'd be the output profile) - also see LCMSAPI.txt
79
+ input colorspace -> using 'renderingIntent' -> proof
80
+ colorspace -> using 'proofRenderingIntent' -> output
81
+ colorspace
82
+
83
+ Added LCMS FLAGS support.
84
+ Added FLAGS["SOFTPROOFING"] as default flag for
85
+ buildProofTransform (otherwise the proof profile/intent
86
+ would be ignored).
87
+
88
+ 0.1.0 pil March 2009 - added to PIL, as PIL.ImageCms
89
+
90
+ 0.0.2 alpha Jan 6, 2002
91
+
92
+ Added try/except statements around type() checks of
93
+ potential CObjects... Python won't let you use type()
94
+ on them, and raises a TypeError (stupid, if you ask
95
+ me!)
96
+
97
+ Added buildProofTransformFromOpenProfiles() function.
98
+ Additional fixes in DLL, see DLL code for details.

+ # History:
8
+ # 1996-04-13 fl Created (experimental)
9
+ # 1996-08-07 fl Filled polygons, ellipses.
10
+ # 1996-08-13 fl Added text support
11
+ # 1998-06-28 fl Handle I and F images
12
+ # 1998-12-29 fl Added arc; use arc primitive to draw ellipses
13
+ # 1999-01-10 fl Added shape stuff (experimental)
14
+ # 1999-02-06 fl Added bitmap support
15
+ # 1999-02-11 fl Changed all primitives to take options
16
+ # 1999-02-20 fl Fixed backwards compatibility
17
+ # 2000-10-12 fl Copy on write, when necessary
18
+ # 2001-02-18 fl Use default ink for bitmap/text also in fill mode
19
+ # 2002-10-24 fl Added support for CSS-style color strings
20
+ # 2002-12-10 fl Added experimental support for RGBA-on-RGB drawing
21
+ # 2002-12-11 fl Refactored low-level drawing API (work in progress)
22
+ # 2004-08-26 fl Made Draw() a factory function, added getdraw() support
23
+ # 2004-09-04 fl Added width support to line primitive
24
+ # 2004-09-10 fl Added font mode handling
25
+ # 2006-06-19 fl Added font bearing support (getmask2)

+ # TIFF file handling
6
+ #
7
+ # TIFF is a flexible, if somewhat aged, image file format originally
8
+ # defined by Aldus. Although TIFF supports a wide variety of pixel
9
+ # layouts and compression methods, the name doesn't really stand for
10
+ # "thousands of incompatible file formats," it just feels that way.
11
+ #
12
+ # To read TIFF data from a stream, the stream must be seekable. For
13
+ # progressive decoding, make sure to use TIFF files where the tag
14
+ # directory is placed first in the file.
15
+ #
16
+ # History:
17
+ # 1995-09-01 fl Created
18

20
+ # 1997-01-05 fl Fixed PREDICTOR support
21
+ # 1997-08-27 fl Added support for rational tags (from Perry Stoll)
22
+ # 1998-01-10 fl Fixed seek/tell (from Jan Blom)

27
+ # 2001-05-12 fl Added write support for more tags (from Greg Couch) (1.3)
28
