28
- ==========
29
-
30
- MarkupSafe implements a text object that escapes characters so it is
31
- safe to use in HTML and XML. Characters that have special meanings are
32
- replaced so that they display as the actual characters. This mitigates
33
- injection attacks, meaning untrusted user input can safely be displayed
34
- on a page.

- Examples
50
- --------
51
-
52
- .. code-block:: pycon
53
-
54
- >>> from markupsafe import Markup, escape
55
-
56
- >>> # escape replaces special characters and wraps in Markup
57
- >>> escape("<script>alert(document.cookie);</script>")
58
- Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
59
-
60
- >>> # wrap in Markup to mark text "safe" and prevent escaping
61
- >>> Markup("<strong>Hello</strong>")
62
- Markup('<strong>hello</strong>')
63
-
64
- >>> escape(Markup("<strong>Hello</strong>"))
65
- Markup('<strong>hello</strong>')
66
-
67
- >>> # Markup is a str subclass
68
- >>> # methods and operators escape their arguments
69
- >>> template = Markup("Hello <em>{name}</em>")
70
- >>> template.format(name='"World"')

- BLP1 files, used mostly in Warcraft III, are not fully supported.
10
- All types of BLP2 files used in World of Warcraft are supported.
11
-
12
- The BLP file structure consists of a header, up to 16 mipmaps of the
13
- texture
14
-
15
- Texture sizes must be powers of two, though the two dimensions do
16
- not have to be equal; 512x256 is valid, but 512x200 is not.
17
- The first mipmap (mipmap #0) is the full size image; each subsequent
18
- mipmap halves both dimensions. The final mipmap should be 1x1.
19
-
20
- BLP files come in many different flavours:
21
- * JPEG-compressed (type == 0) - only supported for BLP1.
22
- * RAW images (type == 1, encoding == 1). Each mipmap is stored as an
23
- array of 8-bit values, one per pixel, left to right, top to bottom.
24
- Each value is an index to the palette.
25
- * DXT-compressed (type == 1, encoding == 2):
26
- - DXT1 compression is used if alpha_encoding == 0.
27
- - An additional alpha bit is used if alpha_depth == 1.
28
- - DXT3 compression is used if alpha_encoding == 1.
29
- - DXT5 compression is used if alpha_encoding == 7.

- 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

53
- Originally released under LGPL. Graciously donated to PIL in
54
- March 2009, for distribution under the standard PIL license
55
-
56
- The pyCMS.py module provides a "clean" interface between Python/PIL and
57
- pyCMSdll, taking care of some of the more complex handling of the direct
58
- pyCMSdll functions, as well as error-checking and making sure that all
59
- relevant data is kept together.
60
-
61
- While it is possible to call pyCMSdll functions directly, it's not highly
62
- recommended.
63
-
64
- Version History:
65
-
66
- 1.0.0 pil Oct 2013 Port to LCMS 2.
67
-
68
- 0.1.0 pil mod March 10, 2009
69
-
70
- Renamed display profile to proof profile. The proof
71
- profile is the profile of the device that is being
72
- simulated, not the profile of the device which is
73
- actually used to display/print the final simulation
74
- (that'd be the output profile) - also see LCMSAPI.txt
75
- input colorspace -> using 'renderingIntent' -> proof
76
- colorspace -> using 'proofRenderingIntent' -> output
77
- colorspace
78
-
79
- Added LCMS FLAGS support.
80
- Added FLAGS["SOFTPROOFING"] as default flag for
81
- buildProofTransform (otherwise the proof profile/intent
82
- would be ignored).
83
-
84
- 0.1.0 pil March 2009 - added to PIL, as PIL.ImageCms
85
-
86
- 0.0.2 alpha Jan 6, 2002
87
-
88
- Added try/except statements around type() checks of
89
- potential CObjects... Python won't let you use type()
90
- on them, and raises a TypeError (stupid, if you ask
91
- me!)
92
-
93
- Added buildProofTransformFromOpenProfiles() function.
94
- Additional fixes in DLL, see DLL code for details.
95
-
96

- ``proofRenderingIntent`` to determine what to do with out-of-gamut
637
- colors. This is known as "soft-proofing". It will ONLY work for
638
- converting images that are in ``inMode`` to images that are in outMode
639
- color format (PIL mode, i.e. "RGB", "RGBA", "CMYK", etc.).
640
-
641
- Usage of the resulting transform object is exactly the same as with
642
- ImageCms.buildTransform().
643
-
644
- Proof profiling is generally used when using an output device to get a
645
- good idea of what the final printed/displayed image would look like on
646
- the ``proofProfile`` device when it's quicker and easier to use the
647
- output device for judging color. Generally, this means that the
648
- output device is a monitor, or a dye-sub printer (etc.), and the simulated
649
- device is something more expensive, complicated, or time consuming
650
- (making it difficult to make a real print for color judgement purposes).
651
-
652
- Soft-proofing basically functions by adjusting the colors on the
653
- output device to match the colors of the device being simulated. However,
654
- when the simulated device has a much wider gamut than the output
655
- device, you may obtain marginal results.

- # 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)

- # History:
8
- # 1996-08-07 fl created (experimental)
9
- # 1997-08-25 fl minor adjustments to handle fonts from pilfont 0.3
10
- # 1999-02-06 fl rewrote most font management stuff in C
11
- # 1999-03-17 fl take pth files into account in load_path (from Richard Jones)
12
- # 2001-02-17 fl added freetype support
13
- # 2001-05-09 fl added TransposedFont wrapper class
14
- # 2002-03-04 fl make sure we have a "L" or "1" font
15
- # 2002-12-04 fl skip non-directory entries in the system path
16
- # 2003-04-29 fl add embedded default font
17
- # 2003-09-27 fl added support for truetype charmap encodings
