.Synopsis
Activate a Python virtual environment for the current PowerShell session.
.Description
Pushes the python executable for a virtual environment to the front of the
$Env:PATH environment variable and sets the prompt to signify that you are
in a Python virtual environment. Makes use of the command line switches as
well as the `pyvenv.cfg` file values present in the virtual environment.
.Parameter VenvDir
Path to the directory that contains the virtual environment to activate. The
default value for this is the parent of the directory that the Activate.ps1
script is located within.
.Parameter Prompt
The prompt prefix to display when this virtual environment is activated. By
default, this prompt is the name of the virtual environment folder (VenvDir)
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
.Example
Activate.ps1
Activates the Python virtual environment that contains the Activate.ps1 script.
.Example
Activate.ps1 -Verbose
Activates the Python virtual environment that contains the Activate.ps1 script,
and shows extra information about the activation as it executes.
.Example
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
Activates the Python virtual environment located in the specified location.
.Example
Activate.ps1 -Prompt "MyPython"
Activates the Python virtual environment that contains the Activate.ps1 script,
and prefixes the current prompt with the specified string (surrounded in
parentheses) while the virtual environment is active.
.Notes
On Windows, it may be required to enable this Activate.ps1 script by setting the
execution policy for the user. You can do this by issuing the following PowerShell
command:
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
For more information on Execution Policies:

.Synopsis
Remove all shell session elements added by the Activate script, including the
addition of the virtual environment's Python executable from the beginning of
the PATH variable.
.Parameter NonDestructive
If present, do not remove this function from the global namespace for the
session.

.Description
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
given folder, and returns them in a map.
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
two strings separated by `=` (with any amount of whitespace surrounding the =)
then it is considered a `key = value` line. The left hand string is the key,
the right hand is the value.
If the value starts with a `'` or a `"` then the first and last character is
stripped from the value before being captured.
.Parameter ConfigDir
Path to the directory that contains the `pyvenv.cfg` file.

Blizzard Mipmap Format (.blp)

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

Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
packed custom format called FTEX. This file format uses file extensions FTC
and FTU.
* FTC files are compressed textures (using standard texture compression).
* FTU files are not compressed.
Texture File Format
The FTC and FTU texture files both use the same format. This
has the following structure:
{header}
{format_directory}
{data}
Where:
{header} = {
u32:magic,
u32:version,
u32:width,
u32:height,
u32:mipmap_count,
u32:format_count
}
* The "magic" number is "FTEX".
* "width" and "height" are the dimensions of the texture.
* "mipmap_count" is the number of mipmaps in the texture.
* "format_count" is the number of texture formats (different versions of the
same texture) in this file.
{format_directory} = format_count * { u32:format, u32:where }
The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
uncompressed textures.
The texture data for a format starts at the position "where" in the file.
Each set of texture data in the file has the following structure:
{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
* "mipmap_size" is the number of bytes in that mip level. For compressed
textures this is the size of the texture data compressed with DXT1. For 24 bit
uncompressed textures, this is 3 * width * height. Following this are the image
bytes for that mipmap level.
Note: All data is stored in little-Endian (Intel) byte order.

PIL read-only image support for Microsoft Windows .ico files.
By default the largest resolution image in the file will be loaded. This
can be changed by altering the 'size' attribute before calling 'load'.
The info dictionary has a key 'sizes' that is a list of the sizes available
in the icon file.
Handles classic, XP and Vista icon formats.
When saving, PNG compression is used. Support for this was only added in
Windows Vista.

pyCMS

(littleCMS is Copyright (C) 1998-2001 Marti Maria)
Originally released under LGPL. Graciously donated to PIL in
March 2009, for distribution under the standard PIL license
The pyCMS.py module provides a "clean" interface between Python/PIL and
pyCMSdll, taking care of some of the more complex handling of the direct
pyCMSdll functions, as well as error-checking and making sure that all
relevant data is kept together.
While it is possible to call pyCMSdll functions directly, it's not highly
recommended.
Version History:
1.0.0 pil Oct 2013 Port to LCMS 2.
0.1.0 pil mod March 10, 2009
Renamed display profile to proof profile. The proof
profile is the profile of the device that is being
simulated, not the profile of the device which is
actually used to display/print the final simulation
(that'd be the output profile) - also see LCMSAPI.txt
input colorspace -> using 'renderingIntent' -> proof
colorspace -> using 'proofRenderingIntent' -> output
colorspace
Added LCMS FLAGS support.
Added FLAGS["SOFTPROOFING"] as default flag for
buildProofTransform (otherwise the proof profile/intent
would be ignored).
0.1.0 pil March 2009 - added to PIL, as PIL.ImageCms
0.0.2 alpha Jan 6, 2002
Added try/except statements around type() checks of
potential CObjects... Python won't let you use type()
on them, and raises a TypeError (stupid, if you ask
me!)
Added buildProofTransformFromOpenProfiles() function.
Additional fixes in DLL, see DLL code for details.
0.0.1 alpha first public release, Dec. 26, 2002
Known to-do list with current version (of Python interface, not pyCMSdll):
none

Building the transform is a fair part of the overhead in

images using the same input/output settings, this can save you time.
Once you have a transform object, it can be used with
ImageCms.applyProfile() to convert images without the need to re-compute
the lookup table for the transform.
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

This function builds and returns an ICC transform from the ``inputProfile``

converting images that are in ``inMode`` to images that are in outMode
color format (PIL mode, i.e. "RGB", "RGBA", "CMYK", etc.).
Usage of the resulting transform object is exactly the same as with
ImageCms.buildTransform().
Proof profiling is generally used when using an output device to get a
good idea of what the final printed/displayed image would look like on
the ``proofProfile`` device when it's quicker and easier to use the
output device for judging color. Generally, this means that the
output device is a monitor, or a dye-sub printer (etc.), and the simulated
device is something more expensive, complicated, or time consuming
(making it difficult to make a real print for color judgement purposes).
Soft-proofing basically functions by adjusting the colors on the
output device to match the colors of the device being simulated. However,
when the simulated device has a much wider gamut than the output
device, you may obtain marginal results.

(pyCMS) Checks if a given intent is supported.
Use this function to verify that you can use your desired
``intent`` with ``profile``, and that ``profile`` can be used for the
input/output/proof profile as you desire.
Some profiles are created specifically for one "direction", can cannot
be used for others. Some profiles can only be used for certain
rendering intents, so it's best to either verify this before trying
to create a transform with them (using this function), or catch the
potential :exc:`PyCMSError` that will occur if they don't
support the modes you select.

filename of an ICC profile.

use with this profile
