+.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:

+.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

+
+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.

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

+JPEG quality settings equivalent to the Photoshop settings.
+Can be used when saving JPEG files.
+
+The following presets are available by default:
+``web_low``, ``web_medium``, ``web_high``, ``web_very_high``, ``web_maximum``,
+``low``, ``medium``, ``high``, ``maximum``.
+More presets can be added to the :py:data:`presets` dict if needed.
+
+To apply the preset, specify::
+
+  quality="preset_name"
+
+To apply only the quantization table::
+
+  qtables="preset_name"
+
+To apply only the subsampling setting::
+
+  subsampling="preset_name"
+
+Example::
+
+  im.save("image_name.jpg", quality="web_high")
+
+Subsampling
+-----------
+
+Subsampling is the practice of encoding images by implementing less resolution
+for chroma information than for luma information.
+(ref.: https://en.wikipedia.org/wiki/Chroma_subsampling)
+
+Possible subsampling values are 0, 1 and 2 that correspond to 4:4:4, 4:2:2 and
+4:2:0.
+
+You can get the subsampling of a JPEG with the
+:func:`.JpegImagePlugin.get_sampling` function.
+
+In JPEG compressed data a JPEG marker is used instead of an EXIF tag.
+(ref.: https://exiv2.org/tags.html)
+
+
+Quantization tables
+-------------------
+
+They are values use by the DCT (Discrete cosine transform) to remove
+*unnecessary* information from the image (the lossy part of the compression).
+(ref.: https://en.wikipedia.org/wiki/Quantization_matrix#Quantization_matrices,
+https://en.wikipedia.org/wiki/JPEG#Quantization)
+
+You can get the quantization tables of a JPEG with::
+
+  im.quantization
+
+This will return a dict with a number of lists. You can pass this dict
+directly as the qtables argument when saving a JPEG.
+
+The quantization table format in presets is a list with sublists. These formats
+are interchangeable.
