+ MarkupSafe
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.

+ Installing
38
+ ----------

+
40
+ Install and update using `pip`_:
41
+
42
+ .. code-block:: text
43
+
44
+ pip install -U MarkupSafe
45
+
46
+ .. _pip: https://pip.pypa.io/en/stable/getting-started/
47
+
48
+
49
+ 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>')

+ 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
+ Note: All data is stored in little-Endian (Intel) byte order.

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.

+ # 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)
