2
- .Synopsis
3
- Activate a Python virtual environment for the current PowerShell session.
4
-
5
- .Description
6
- Pushes the python executable for a virtual environment to the front of the
7
- $Env:PATH environment variable and sets the prompt to signify that you are
8
- in a Python virtual environment. Makes use of the command line switches as
9
- well as the `pyvenv.cfg` file values present in the virtual environment.
10
-
11
- .Parameter VenvDir
12
- Path to the directory that contains the virtual environment to activate. The
13
- default value for this is the parent of the directory that the Activate.ps1
14
- script is located within.
15
-
16
- .Parameter Prompt
17
- The prompt prefix to display when this virtual environment is activated. By
18
- default, this prompt is the name of the virtual environment folder (VenvDir)
19
- surrounded by parentheses and followed by a single space (ie. '(.venv) ').
20
-
21
- .Example
22
- Activate.ps1
23
- Activates the Python virtual environment that contains the Activate.ps1 script.
24
-
25
- .Example
26
- Activate.ps1 -Verbose
27
- Activates the Python virtual environment that contains the Activate.ps1 script,
28
- and shows extra information about the activation as it executes.
29
-
30
- .Example
31
- Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
32
- Activates the Python virtual environment located in the specified location.
33
-
34
- .Example
35
- Activate.ps1 -Prompt "MyPython"
36
- Activates the Python virtual environment that contains the Activate.ps1 script,
37
- and prefixes the current prompt with the specified string (surrounded in
38
- parentheses) while the virtual environment is active.
39
-
40
- .Notes
41
- On Windows, it may be required to enable this Activate.ps1 script by setting the
42
- execution policy for the user. You can do this by issuing the following PowerShell
43
- command:
44
-
45
- PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
46

- 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.

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.

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.
99
-
100
- 0.0.1 alpha first public release, Dec. 26, 2002
101

- # 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

8
- # 1995-09-09 fl Created
9
- # 1996-03-11 fl Fixed load mechanism.
10
- # 1996-04-15 fl Added pcx/xbm decoders.
11
- # 1996-04-30 fl Added encoders.
12
- # 1996-12-14 fl Added load helpers
13

14
- # 1997-08-27 fl Flush output in _save
15
- # 1998-03-05 fl Use memory mapping for some modes
16
- # 1999-02-04 fl Use memory mapping also for "I;16" and "I;16B"
17
- # 1999-05-31 fl Added image parser
18
- # 2000-10-12 fl Set readonly flag on memory-mapped images
19
