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.

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.

# DCX is a container file format defined by Intel, commonly used
|
8 |
-
# for fax applications. Each DCX file consists of a directory
|
9 |
-
# (a list of file offsets) followed by a set of (usually 1-bit)
|
10 |
-
# PCX files.

# History:
|
13 |
-
# 1995-09-09 fl Created
|
14 |
-
# 1996-03-20 fl Properly derived from PcxImageFile.
|
15 |
-
# 1998-07-15 fl Renamed offset attribute to avoid name clash
|
16 |
-
# 2002-07-30 fl Fixed file handling

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,

textures this is the size of the texture data compressed with DXT1. For 24 bit

bytes for that mipmap level.

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.

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 |

Building the transform is a fair part of the overhead in

ImageCms.profileToProfile(), so if you're planning on converting multiple

554 |

images using the same input/output settings, this can save you time.

Once you have a transform object, it can be used with

the lookup table for the transform.

558 |
-

559 |

The reason pyCMS returns a class object rather than a handle directly

to the transform is that it needs to keep track of the PIL input/output

modes that the transform is meant for. These attributes are stored in

-
the ``inMode`` and ``outMode`` attributes of the object (which can be

manually overridden if you really want to, but I don't know of any

time that would be of use, or would even work).

This function builds and returns an ICC transform from the ``inputProfile``
|
634 |
-
to the ``outputProfile``, but tries to simulate the result that would be
|
635 |
-
obtained on the ``proofProfile`` device using ``renderingIntent`` and
|
636 |
-
``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.

1. Compute the following variables

-
- theta: Angle between the apothem & the nearest polygon vertex
|
1086 |
-
- side_length: Length of each polygon edge
|
1087 |
-
- centroid: Center of bounding circle (1st, 2nd elements of bounding_circle)
|
1088 |
-
- polygon_radius: Polygon radius (last element of bounding_circle)
|
1089 |
-
- angles: Location of each polygon vertex in polar grid
|
1090 |
-
(e.g. A square with 0 degree rotation => [225.0, 315.0, 45.0, 135.0])
|
1091 |
-
|
1092 |
-
2. For each angle in angles, get the polygon vertex at that angle
|
1093 |
-
The vertex is computed using the equation below.
|
1094 |
-
X= xcos(φ) + ysin(φ)
|
1095 |
-
Y= −xsin(φ) + ycos(φ)

-
x = 0
|
1100 |
-
y = polygon_radius
|
1101 |
-
|
1102 |
-
The formula above assumes rotation around the origin.
|
1103 |
-
In our case, we are rotating around the centroid.
|
1104 |
-
To account for this, we use the formula below
|
1105 |
-
X = xcos(φ) + ysin(φ) + centroid_x
|

-
Y = −xsin(φ) + ycos(φ) + centroid_y

# 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
|
18 |
-
#
|
19 |
-
# Todo:
|
20 |
-
# Adapt to PILFONT2 format (16-bit fonts, compressed, single file)
