Unlike traditional Mono/.NET, code on the iPhone is statically compiled ahead of time instead of being
compiled on demand by a JIT compiler. This means there are a few limitations with respect to generics,
these are caused because not every possible generic instantiation can be determined up front at compile time.
The Aot Compiler is designed to overcome the limitations of this compiler.
None of the methods in this class should ever be called, the code only has to exist at compile-time to be picked up by the AoT compiler.
(Very similar to the LinkerIncludes.cs technique used in Xamarin.Android projects.)
This is the method that seeds the AoT compiler.
None of these seed methods needs to actually be called to seed the compiler.
The calls just need to be present when the code is compiled, and each implementation will be built.
This method doesn't actually do anything but serves an important purpose...
If you are running ImageSharp on iOS and try to call SaveAsGif, it will throw an exception:
"Attempting to JIT compile method... OctreeFrameQuantizer.ConstructPalette... while running in aot-only mode."
The reason this happens is the SaveAsGif method makes heavy use of generics, which are too confusing for the AoT
compiler used on Xamarin.iOS. It spins up the JIT compiler to try and figure it out, but that is an illegal op on
iOS so it bombs out.
If you are getting the above error, you need to call this method, which will pre-seed the AoT compiler with the
necessary methods to complete the SaveAsGif call. That's it, otherwise you should NEVER need this method!!!

Strategies for deflater
The default strategy
This strategy will only allow longer string repetitions. It is
useful for random data with a small character set.
This strategy will not look for string repetitions at all. It
only encodes with Huffman trees (which means, that more common
characters get a smaller encoding.
Low level compression engine for deflate algorithm which uses a 32K sliding window
with secondary compression from Huffman/Shannon-Fano codes.
Points to the current character in the window.
lookahead is the number of characters starting at strstart in
window that are valid.
So window[strstart] until window[strstart+lookahead-1] are valid
characters.

The offset into inputBuf, where input data starts.
The end offset of the input data.
Hashtable, hashing three characters to an index for window, so
that window[index]..window[index+2] have this hash code.
Note that the array should really be unsigned short, so you need
to and the values with 0xFFFF.
prev[index & WMASK] points to the previous index that has the
same hash code as the string starting at index. This way
entries with the same hash code are in a linked list.
Note that the array should really be unsigned short, so you need
to and the values with 0xFFFF.

24 bits per pixel. Each pixel consists of 3 bytes.
32 bits per pixel. Each pixel consists of 4 bytes.
Defines the compression type of the image data
in the bitmap file.
Each image row has a multiple of four elements. If the
row has less elements, zeros will be added at the right side.
The format depends on the number of bits, stored in the info header.
If the number of bits are one, four or eight each pixel data is
a index to the palette. If the number of bits are sixteen,
twenty-four or thirty-two each pixel contains a color.
Two bytes are one data record. If the first byte is not zero, the
next byte will be repeated as much as the value of the first byte.
If the first byte is zero, the record has different meanings, depending
on the second byte. If the second byte is zero, it is the end of the row,
if it is one, it is the end of the image.
Two bytes are one data record. If the first byte is not zero, the
next two half bytes will be repeated as much as the value of the first byte.
If the first byte is zero, the record has different meanings, depending
on the second byte. If the second byte is zero, it is the end of the row,
if it is one, it is the end of the image.

OS/2 specific compression type.
Similar to run length encoding of 4 and 8 bit.
The only difference is that run values encoded are three bytes in size (one byte per RGB color component),
rather than four or eight bits in size.
Note: Because compression value of 4 is ambiguous for BI_RGB for windows and RLE24 for OS/2, the enum value is remapped
to a different value, to be clearly separate from valid windows values.

Algorithm: use open addressing double hashing (no chaining) on the
prefix code / next character combination. We do a variant of Knuth's
algorithm D (vol. 3, sec. 6.4) along with G. Knott's relatively-prime
secondary probe. Here, the modular division first probe is gives way
to a faster exclusive-or manipulation. Also do block compression with
an adaptive reset, whereby the code table is cleared when the compression
ratio decreases, but after the table fills. The variable-length output
codes are re-sized at this point, and a special CLEAR code is generated
for the decompressor. Late addition: construct the table according to
file size for noticeable speed improvement on small files. Please direct
questions about this implementation to ames!jaw.

Gets the collection of huffman values.
Maximum number of bytes encoded jpeg 8x8 block can occupy.
It's highly unlikely for block to occupy this much space - it's a theoretical limit.
Where 16 is maximum huffman code binary length according to itu
specs. 10 is maximum value binary length, value comes from discrete
cosine tranform with value range: [-1024..1023]. Block stores
8x8 = 64 values thus multiplication by 64. Then divided by 8 to get
the number of bytes. This value is then multiplied by
for performance reasons.
Multiplier used within cache buffers size calculation.
Theoretically, bytes buffer can fit
exactly one minimal coding unit. In reality, coding blocks occupy much
less space than the theoretical maximum - this can be exploited.
If temporal buffer size is multiplied by at least 2, second half of
the resulting buffer will be used as an overflow 'guard' if next
block would occupy maximum number of bytes. While first half may fit
many blocks before needing to flush.
This is subject to change. This can be equal to 1 but recomended
value is 2 or even greater - futher benchmarking needed.
size multiplier.
Jpeg specification requiers to insert 'stuff' bytes after each
0xff byte value. Worst case scenarion is when all bytes are 0xff.
While it's highly unlikely (if not impossible) to get such
combination, it's theoretically possible so buffer size must be guarded.

Emits the most significant count of bits to the buffer.
Supports up to 32 count of bits but, generally speaking, jpeg
standard assures that there won't be more than 16 bits per single
value.
Emitting algorithm uses 3 intermediate buffers for caching before
writing to the stream:
-
uint32
Bit buffer. Encoded spectral values can occupy up to 16 bits, bits
are assembled to whole bytes via this intermediate buffer.
-
uint32[]
Assembled bytes from uint32 buffer are saved into this buffer.
uint32 buffer values are saved using indices from the last to the first.
As bytes are saved to the memory as 4-byte packages endianness matters:
Jpeg stream is big-endian, indexing buffer bytes from the last index to the
first eliminates all operations to extract separate bytes. This only works for
little-endian machines (there are no known examples of big-endian users atm).
For big-endians this approach is slower due to the separate byte extraction.

Gets span of zig-zag ordering indices.
When reading corrupted data, the Huffman decoders could attempt
to reference an entry beyond the end of this array (if the decoded
zero run length reaches past the end of the block). To prevent
wild stores without adding an inner-loop test, we put some extra
"63"s after the real entries. This will cause the extra coefficient
to be stored in location 63 of the block, not somewhere random.
The worst case would be a run-length of 15, which means we need 16
fake entries.

This allows PNG decoders to recover the original data losslessly even if the data had a sample depth not directly supported by PNG.
If the sRGB chunk is present, the image samples conform to the sRGB colour space [IEC 61966-2-1] and should be displayed
using the specified rendering intent defined by the International Color Consortium.
The hIST chunk gives the approximate usage frequency of each colour in the palette.
The sPLT chunk contains the suggested palette.
The cHRM chunk may be used to specify the 1931 CIE x,y chromaticities of the red,
green, and blue display primaries used in the image, and the referenced white point.

Provides enumeration of available PNG filter methods.
With the None filter, the scanline is transmitted unmodified.
The Sub filter transmits the difference between each byte and the value of the corresponding
byte of the prior pixel.
The Up filter is just like the filter except that the pixel immediately above the current pixel,
rather than just to its left, is used as the predictor.
The Average filter uses the average of the two neighboring pixels (left and above) to predict the value of a pixel.
The Paeth filter computes a simple linear function of the three neighboring pixels (left, above, upper left),
then chooses as predictor the neighboring pixel closest to the computed value.
Computes the output scanline using all five filters, and selects the filter that gives the smallest sum of
absolute values of outputs.
This method usually outperforms any single fixed filter choice.

Encodes and compresses the image data using dynamic Lempel-Ziv compression.
This code is based on the used for GIF encoding. There is potential
for a shared implementation. Differences between the GIF and TIFF implementations of the LZW
encoding are: (i) The GIF implementation includes an initial 'data size' byte, whilst this is
always 8 for TIFF. (ii) The GIF implementation writes a number of sub-blocks with an initial
byte indicating the length of the sub-block. In TIFF the data is written as a single block
with no length indicator (this can be determined from the 'StripByteCounts' entry).

The GetLengthCost(costModel, k) are cached in a CostCacheInterval.
To perform backward reference every pixel at index index_ is considered and
the cost for the MAX_LENGTH following pixels computed. Those following pixels
at index index_ + k (k from 0 to MAX_LENGTH) have a cost of:
cost = distance cost at index + GetLengthCost(costModel, k)
and the minimum value is kept. GetLengthCost(costModel, k) is cached in an
array of size MAX_LENGTH.
Instead of performing MAX_LENGTH comparisons per pixel, we keep track of the
minimal values using intervals of constant cost.
An interval is defined by the index_ of the pixel that generated it and
is only useful in a range of indices from start to end (exclusive), i.e.
it contains the minimum value for pixels between start and end.
Intervals are stored in a linked list and ordered by start. When a new
interval has a better value, old intervals are split or removed. There are
therefore no overlapping intervals.
The CostManager is in charge of managing intervals and costs.
It caches the different CostCacheInterval, caches the different
GetLengthCost(costModel, k) in costCache and the CostInterval's.

contribution is added to the costs right away.
Pop an interval from the manager.
The interval to remove.
Given a current orphan interval and its previous interval, before
it was orphaned (which can be NULL), set it at the right place in the list
of intervals using the start_ ordering and the previous interval as a hint.
Given two intervals, make 'prev' be the previous one of 'next' in 'manager'.
Given the cost and the position that define an interval, update the cost at
pixel 'i' if it is smaller than the previously computed value.

The pixel data to apply the reverse transform on.
The goal of the color transform is to de-correlate the R, G and B values of each pixel.

with respect to predictions. If nearLosslessQuality < 100, applies
near lossless processing, shaving off more bits of residuals for lower qualities.
Returns best predictor and updates the accumulated histogram.
If maxQuantization > 1, assumes that near lossless processing will be
applied, quantizing residuals to multiples of quantization levels up to
maxQuantization (the actual quantization level depends on smoothness near
the given pixel).
Best predictor.
Stores the difference between the pixel and its prediction in "output".
In case of a lossy encoding, updates the source image to avoid propagating
the deviation further to pixels which depend on the current pixel for their
predictions.
Quantize every component of the difference between the actual pixel value and
its prediction to a multiple of a quantization (a power of 2, not larger than
maxQuantization which is a power of 2, smaller than maxDiff). Take care if
value and predict have undergone subtract green, which means that red and
blue are represented as offsets from green.
Quantize the difference between the actual component value and its prediction
to a multiple of quantization, working modulo 256, taking care not to cross
a boundary (inclusive upper limit).
Converts pixels of the image to residuals with respect to predictions.
If max_quantization > 1, applies near lossless processing, quantizing
residuals to multiples of quantization levels up to max_quantization
(the actual quantization level depends on smoothness near the given pixel).

Enum for the different transform types. Transformations are reversible manipulations of the image data
that can reduce the remaining symbolic entropy by modeling spatial and color correlations.
Transformations can make the final compression more dense.
The predictor transform can be used to reduce entropy by exploiting the fact that neighboring pixels are often correlated.
The goal of the color transform is to de-correlate the R, G and B values of each pixel.
Color transform keeps the green (G) value as it is, transforms red (R) based on green and transforms blue (B) based on green and then based on red.
The subtract green transform subtracts green values from red and blue values of each pixel.
When this transform is present, the decoder needs to add the green value to both red and blue.
There is no data associated with this transform.
If there are not many unique pixel values, it may be more efficient to create a color index array and replace the pixel values by the array's indices.
The color indexing transform achieves this.

Wraps an existing contiguous memory area of at least 'width' x 'height' pixels allowing viewing/manipulation as
an instance.
Please note: using this method does not transfer the ownership of the underlying buffer of the input
to the new instance. This means that consumers of this method must ensure that the input buffer
is either self-contained, (for example, a instance wrapping a new array that was
created), or that the owning object is not disposed until the returned is disposed.
If the input instance is one retrieved from an instance
rented from a memory pool (such as ), and that owning instance is disposed while the image is still
in use, this will lead to undefined behavior and possibly runtime crashes (as the same buffer might then be modified by other
consumers while the returned image is still working on it). Make sure to control the lifetime of the input buffers appropriately.

Please note: this method relies on callers to carefully manage the target memory area being referenced by the
pointer and that the lifetime of such a memory area is at least equal to that of the returned
instance. For example, if the input pointer references an unmanaged memory area,
callers must ensure that the memory area is not freed as long as the returned is
in use and not disposed. The same applies if the input memory area points to a pinned managed object, as callers
must ensure that objects will remain pinned as long as the instance is in use.
Failing to do so constitutes undefined behavior and will likely lead to memory corruption and runtime crashes.
Note also that if you have a or an array (which can be cast to ) of
either or values, it is highly recommended to use one of the other
available overloads of this method instead (such as

prone and avoid having to pin the underlying memory buffer in use. This method is primarily meant to be used when

Used in the TIFF-FX standard to point to an IFD containing tags that are globally applicable to the complete TIFF file.
See RFC2301: TIFF-F/FX Specification.
It is recommended that a TIFF writer place this field in the first IFD, where a TIFF reader would find it quickly.
Each field in the GlobalParametersIFD is a TIFF field that is legal in any IFD. Required baseline fields should not be located in the GlobalParametersIFD, but should be in each image IFD. If a conflict exists between fields in the GlobalParametersIFD and in the image IFDs, then the data in the image IFD shall prevail.

Used in interchangeable GeoTIFF files.
See https://www.awaresystems.be/imaging/tiff/tifftags/geokeydirectorytag.html
This tag is also know as 'ProjectionInfoTag' and 'CoordSystemInfoTag'
This tag may be used to store the GeoKey Directory, which defines and references the "GeoKeys".
Used in interchangeable GeoTIFF files.
See https://www.awaresystems.be/imaging/tiff/tifftags/geodoubleparamstag.html
This tag is used to store all of the DOUBLE valued GeoKeys, referenced by the GeoKeyDirectoryTag. The meaning of any value of this double array is determined from the GeoKeyDirectoryTag reference pointing to it. FLOAT values should first be converted to DOUBLE and stored here.
Used in interchangeable GeoTIFF files.
See https://www.awaresystems.be/imaging/tiff/tifftags/geoasciiparamstag.html
This tag is used to store all of the ASCII valued GeoKeys, referenced by the GeoKeyDirectoryTag. Since keys use offsets into tags, any special comments may be placed at the beginning of this tag. For the most part, the only keys that are ASCII valued are "Citation" keys, giving documentation and references for obscure projections, datums, etc.

profiles are N-component LUT-based, Three-component matrix-based,
and monochrome.
This class of profiles represents display devices such as monitors.
The types of profiles available for use as Display profiles are
N-component LUT-based, Three-component matrix-based, and monochrome.
Output profiles are used to support devices such as printers and
film recorders. The types of profiles available for use as Output
profiles are N-component LUT-based and Monochrome.
This profile contains a pre-evaluated transform that cannot be undone,
which represents a one-way link or connection between devices. It does
not represent any device model nor can it be embedded into images.
This profile provides the relevant information to perform a transformation
between color encodings and the PCS. This type of profile is based on
modeling rather than device measurement or characterization data.
ColorSpace profiles may be embedded in images.
This profile represents abstract transforms and does not represent any
device model. Color transformations using Abstract profiles are performed
from PCS to PCS. Abstract profiles cannot be embedded in images.
NamedColor profiles can be thought of as sibling profiles to device profiles.
For a given device there would be one or more device profiles to handle
process color conversions and one or more named color profiles to handle
named colors.
Profile flags. Can be combined with a logical OR.
The least-significant 16 bits are reserved for the ICC,
the rest can be used for vendor specific values
No flags (equivalent to NotEmbedded and Independent)

Rendering intent
In perceptual transforms the PCS values represent hypothetical
measurements of a color reproduction on the reference reflective
medium. By extension, for the perceptual intent, the PCS represents
the appearance of that reproduction as viewed in the reference viewing
environment by a human observer adapted to that environment. The exact
color rendering of the perceptual intent is vendor specific.
Transformations for this intent shall re-scale the in-gamut,
chromatically adapted tristimulus values such that the white
point of the actual medium is mapped to the PCS white point
(for either input or output)
The exact color rendering of the saturation intent is vendor
specific and involves compromises such as trading off
preservation of hue in order to preserve the vividness of pure colors.
Transformations for this intent shall leave the chromatically
adapted nCIEXYZ tristimulus values of the in-gamut colors unchanged.

The chromaticity tag type provides basic chromaticity data and type of
phosphors or colorants of a monitor to applications and utilities
This is an optional tag which specifies the laydown order in which colorants
will be printed on an n-colorant device. The laydown order may be the same
as the channel generation order listed in the colorantTableTag or the channel
order of a color encoding type such as CMYK, in which case this tag is not
needed. When this is not the case (for example, ink-towers sometimes use
the order KCMY), this tag may be used to specify the laydown order of the
colorants
The purpose of this tag is to identify the colorants used in the profile
by a unique name and set of PCSXYZ or PCSLAB values to give the colorant
an unambiguous value. The first colorant listed is the colorant of the
first device channel of a LUT tag. The second colorant listed is the
colorant of the second device channel of a LUT tag, and so on
The curveType embodies a one-dimensional function which maps an input
value in the domain of the function to an output value in the range
of the function
The dataType is a simple data structure that contains either 7-bit ASCII
or binary data
Date and time defined by 6 unsigned 16bit integers
(year, month, day, hour, minute, second)
This structure represents a color transform using tables with 16-bit
precision. This type contains four processing elements: a 3 × 3 matrix
(which shall be the identity matrix unless the input color space is
PCSXYZ), a set of one-dimensional input tables, a multi-dimensional
lookup table, and a set of one-dimensional output tables
This structure represents a color transform using tables of 8-bit
precision. This type contains four processing elements: a 3 × 3 matrix
(which shall be the identity matrix unless the input color space is
PCSXYZ), a set of one-dimensional input tables, a multi-dimensional
lookup table, and a set of one-dimensional output tables.
This structure represents a color transform. The type contains up
to five processing elements which are stored in the AToBTag tag
in the following order: a set of one-dimensional curves, a 3 × 3
matrix with offset terms, a set of one-dimensional curves, a
multi-dimensional lookup table, and a set of one-dimensional
output curves
This structure represents a color transform. The type contains
up to five processing elements which are stored in the BToATag
in the following order: a set of one-dimensional curves, a 3 × 3
matrix with offset terms, a set of one-dimensional curves, a
multi-dimensional lookup table, and a set of one-dimensional curves.
This information refers only to the internal
profile data and is meant to provide profile makers an alternative
to the default measurement specifications
This tag structure contains a set of records each referencing a
multilingual Unicode string associated with a profile. Each string
is referenced in a separate record with the information about what
language and region the string is for.
This structure represents a color transform, containing a sequence
of processing elements. The processing elements contained in the
structure are defined in the structure itself, allowing for a flexible
structure. Currently supported processing elements are: a set of one
dimensional curves, a matrix with offset terms, and a multidimensional
lookup table (CLUT). Other processing element types may be added in
the future. Each type of processing element may be contained any
number of times in the structure.
This type is a count value and array of structures that provide color
coordinates for color names. For each named color, a PCS and optional
device representation of the color are given. Both representations are
16-bit values and PCS values shall be relative colorimetric. The device
representation corresponds to the header’s "data color space" field.
This representation should be consistent with the "number of device
coordinates" field in the namedColor2Type. If this field is 0, device
coordinates are not provided. The PCS representation corresponds to the
header's PCS field. The PCS representation is always provided. Color
names are fixed-length, 32-byte fields including null termination. In
order to maintain maximum portability, it is strongly recommended that
special characters of the 7-bit ASCII set not be used.
This type describes a one-dimensional curve by specifying one of a
predefined set of functions using the parameters.
This type is an array of structures, each of which contains information
from the header fields and tags from the original profiles which were
combined to create the final profile. The order of the structures is
the order in which the profiles were combined and includes a structure
for the final profile. This provides a description of the profile
sequence from source to destination, typically used with the DeviceLink
profile.
This type is an array of structures, each of which contains information
for identification of a profile used in a sequence.
The purpose of this tag type is to provide a mechanism to relate physical
colorant amounts with the normalized device codes produced by lut8Type,
lut16Type, lutAToBType, lutBToAType or multiProcessElementsType tags
so that corrections can be made for variation in the device without
having to produce a new profile. The mechanism can be used by applications
to allow users with relatively inexpensive and readily available
instrumentation to apply corrections to individual output color
channels in order to achieve consistent results.
Array of signed floating point numbers with 1 sign bit, 15 value bits and 16 fractional bits
The signatureType contains a 4-byte sequence. Sequences of less than four
characters are padded at the end with spaces. Typically this type is used
for registered tags that can be displayed on many development systems as
a sequence of four characters.

REMOVED IN V4 - The textDescriptionType is a complex structure that contains three
types of text description structures: 7-bit ASCII, Unicode and ScriptCode. Since no
single standard method for specifying localizable character sets exists across
the major platform vendors, including all three provides access for the major
operating systems. The 7-bit ASCII description is to be an invariant,
nonlocalizable name for consistent reference. It is preferred that both the
Unicode and ScriptCode structures be properly localized.

Provides enumeration of the alpha value transparency behavior of a pixel format.
Indicates that the pixel format does not contain an alpha channel.
Indicates that the transparency behavior is premultiplied.
Each color is first scaled by the alpha value. The alpha value itself is the same
in both straight and premultiplied alpha. Typically, no color channel value is
greater than the alpha channel value.
If a color channel value in a premultiplied format is greater than the alpha
channel, the standard source-over blending math results in an additive blend.
Indicates that the transparency behavior is not premultiplied.
The alpha channel indicates the transparency of the color.
Collection of Porter Duff alpha blending functions applying different composition models.
These functions are designed to be a general solution for all color cases,
that is, they take in account the alpha value of both the backdrop
and source, and there's no need to alpha-premultiply neither the backdrop
nor the source.
Note there are faster functions for when the backdrop color is known
to be opaque

Collection of Porter Duff Color Blending and Alpha Composition Functions.
These functions are designed to be a general solution for all color cases,
that is, they take in account the alpha value of both the backdrop
and source, and there's no need to alpha-premultiply neither the backdrop
nor the source.
Note there are faster functions for when the backdrop color is known
to be opaque

The function implements the bicubic kernel algorithm W(x) as described on
Wikipedia
A commonly used algorithm within image processing that preserves sharpness better than triangle interpolation.
The function implements the box algorithm. Similar to nearest neighbor when upscaling.
When downscaling the pixels will average, merging together.
Cubic filters contain a collection of different filters of varying B-Spline and
Cardinal values. With these two values you can generate any smoothly fitting
(continuious first derivative) piece-wise cubic filter.
The Catmull-Rom filter is a well known standard Cubic Filter often used as a interpolation function.
This filter produces a reasonably sharp edge, but without a the pronounced gradient change on large
scale image enlargements that a 'Lagrange' filter can produce.
The Hermite filter is type of smoothed triangular interpolation Filter,
This filter rounds off strong edges while preserving flat 'color levels' in the original image.
