#ifndef _PYGAME_H
#define _PYGAME_H
/** This header file includes all the definitions for the
** base pygame extensions. This header only requires
** SDL and Python includes. The reason for functions
** prototyped with #define's is to allow for maximum
** python portability. It also uses python as the
** runtime linker, which allows for late binding. For more
** information on this style of development, read the Python
** docs on this subject.
** http://www.python.org/doc/current/ext/using-cobjects.html
**
** If using this to build your own derived extensions,
** you'll see that the functions available here are mainly
** used to help convert between python objects and SDL objects.
** Since this library doesn't add a lot of functionality to
** the SDL libarary, it doesn't need to offer a lot either.
**
** When initializing your extension module, you must manually
** import the modules you want to use. (this is the part about
** using python as the runtime linker). Each module has its
** own import_xxx() routine. You need to perform this import
** after you have initialized your own module, and before
** you call any routines from that module. Since every module
** in pygame does this, there are plenty of examples.
**
** The base module does include some useful conversion routines
** that you are free to use in your own extension.
**
** When making changes, it is very important to keep the
** FIRSTSLOT and NUMSLOT constants up to date for each
** section. Also be sure not to overlap any of the slots.
** When you do make a mistake with this, it will result
** is a dereferenced NULL pointer that is easier to diagnose
** than it could be :]

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.

A Pillow loader for .ftc and .ftu files (FTEX)

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.

(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):

Building the transform is a fair part of the overhead in
ImageCms.profileToProfile(), so if you're planning on converting multiple
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
time that would be of use, or would even work).

This function builds and returns an ICC transform from the inputProfile

proofRenderingIntent to determine what to do with out-of-gamut

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.

"""
JPEG quality settings equivalent to the Photoshop settings.
More presets can be added to the presets dict if needed.
Can be use when saving JPEG file.
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
`JpegImagePlugin.get_subsampling(im)` function.
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 arrays. You can pass this dict
directly as the qtables argument when saving a JPEG.
The tables format between im.quantization and quantization in presets differ in
3 ways:
1. The base container of the preset is a list with sublists instead of dict.
dict[0] -> list[0], dict[1] -> list[1], ...
2. Each table in a preset is a list instead of an array.
3. The zigzag order is remove in the preset (needed by libjpeg >= 6a).
You can convert the dict format to the preset format with the
`JpegImagePlugin.convert_dict_qtables(dict_qtables)` function.

# Read a BYTE value as the RunType

# Read next byte as the RunCount
# Read the next byte as the RunValue
