 This file contains decompression data source routines for the case of
 reading JPEG data from memory or from a file (or any stdio stream).
 While these routines are sufficient for most applications,
 some will want to use a different source manager.
 IMPORTANT: we assume that fread() will correctly transcribe an array of
 JOCTETs from 8-bit-wide elements on external storage.  If char is wider
 than 8 bits on your machine, you may need to do some tweaking.

 This file contains a slower but more accurate integer implementation of the
 inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
 must also perform dequantization of the input coefficients.
 .
 A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
 on each row (or vice versa, but it's more convenient to emit a row at
 a time).  Direct algorithms are also available, but they are much more
 complex and seem not to be any faster when reduced to code.
 .
 This implementation is based on an algorithm described in
 C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
 Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
 Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
 The primary algorithm described there uses 11 multiplies and 29 adds.
 We use their alternate method with 12 multiplies and 32 adds.
 The advantage of this method is that no data path contains more than one
 multiplication; this allows a very simple and accurate implementation in
 scaled fixed-point arithmetic, with a minimal number of shifts.
 .
 We also provide IDCT routines with various output sample block sizes for
 direct resolution reduction or enlargement without additional resampling:

 This file implements djpeg's "-map file" switch.  It reads a source image
 and constructs a colormap to be supplied to the JPEG decompressor.
 .
 Currently, these file formats are supported for the map file:
 GIF: the contents of the GIF's global colormap are used.
 PPM (either text or raw flavor): the entire file is read and
 each unique pixel value is entered in the map.
 Note that reading a large PPM file will be horrendously slow.
 Typically, a PPM-format map file should contain just one pixel
 of each desired color.  Such a file can be extracted from an
 ordinary image PPM file with ppmtomap(1).
 .
 Rescaling a PPM that has a maxval unequal to MAXJSAMPLE is not
 currently implemented.

 This file describes how to use the IJG JPEG library within an application
 program.  Read it if you want to write a program that uses the library.
 .
 The file example.txt provides heavily commented skeleton code for calling the
 JPEG library.  Also see jpeglib.h (the include file to be used by application
 programs) for full details about data structures and function parameter lists.
 The library source code, of course, is the ultimate reference.
 .
 Note that there have been *major* changes from the application interface
 presented by IJG version 4 and earlier versions.  The old design had several
 inherent limitations, and it had accumulated a lot of cruft as we added
 features while trying to minimize application-interface changes.  We have
 sacrificed backward compatibility in the version 5 rewrite, but we think the
 improvements justify this.

 Since numerous people will be contributing code and bug fixes, it's important
 to establish a common coding style.  The goal of using similar coding styles
 is much more important than the details of just what that style is.
 .
 In general we follow the recommendations of "Recommended C Style and Coding
 Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
 Brader).  This document is available in the IJG FTP archive (see
 jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).

 Block comments should be laid out thusly:

 /*
 *  Block comments in this style.

 .
 We indent statements in K&R style, e.g.,
 if (test) {
 then-part;
 } else {
 else-part;
 }
 with two spaces per indentation level.  (This indentation convention is
 handled automatically by GNU Emacs and many other text editors.)

 Much of the complexity here has to do with supporting input suspension.
 If the data source module demands suspension, we want to be able to back
 up to the start of the current MCU.  To do this, we copy state variables
 into local working storage, and update them back to the permanent
 storage only upon successful completion of an MCU.

 This file contains a fast, not so accurate integer implementation of the
 forward DCT (Discrete Cosine Transform).
 .
 A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
 on each column.  Direct algorithms are also available, but they are
 much more complex and seem not to be any faster when reduced to code.
 .
 This implementation is based on Arai, Agui, and Nakajima's algorithm for
 scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
 Japanese, but the algorithm is described in the Pennebaker & Mitchell
 JPEG textbook (see REFERENCES section in file README.ijg).  The following
 code is based directly on figure 4-8 in P&M.
 While an 8-point DCT cannot be done in less than 11 multiplies, it is
 possible to arrange the computation so that many of the multiplies are
 simple scalings of the final outputs.  These multiplies can then be
 folded into the multiplications or divisions by the JPEG quantization
 table entries.  The AA&N method leaves only 5 multiplies and 29 adds
 to be done in the DCT itself.
 The primary disadvantage of this method is that with fixed-point math,
 accuracy is lost due to imprecise representation of the scaled
 quantization values.  The smaller the quantization table entry, the less
 precise the scaled value, so this implementation does worse with high-
 quality-setting files than with low-quality ones.

 on the hardware's floating point capacity.

 This file provides an overview of the architecture of the IJG JPEG software;
 that is, the functions of the various modules in the system and the interfaces
 between modules.  For more precise details about any data structure or calling
 convention, see the include files and comments in the source code.
 .
 We assume that the reader is already somewhat familiar with the JPEG standard.
 The README.ijg file includes references for learning about JPEG.  The file
 libjpeg.txt describes the library from the viewpoint of an application
 programmer using the library; it's best to read that file before this one.
 Also, the file coderules.txt describes the coding style conventions we use.
 .
 In this document, JPEG-specific terminology follows the JPEG standard:
 A "component" means a color channel, e.g., Red or Luminance.
 A "sample" is a single component value (i.e., one number in the image data).
 A "coefficient" is a frequency coefficient (a DCT transform output number).
 A "block" is an 8x8 group of samples or coefficients.
 An "MCU" (minimum coded unit) is an interleaved set of blocks of size
 determined by the sampling factors, or a single block in a
 noninterleaved scan.
 We do not use the terms "pixel" and "sample" interchangeably.  When we say
 pixel, we mean an element of the full-size image, while a sample is an element
 of the downsampled image.  Thus the number of samples may vary across
 components while the number of pixels does not.  (This terminology is not used
 rigorously throughout the code, but it is used in places where confusion would
 otherwise result.)
 .
 *** System features ***
 .
 The IJG distribution contains two parts:
 * A subroutine library for JPEG compression and decompression.
 * cjpeg/djpeg, two sample applications that use the library to transform
 JFIF JPEG files to and from several other image formats.
 cjpeg/djpeg are of no great intellectual complexity: they merely add a simple
 command-line user interface and I/O routines for several uncompressed image
 formats.  This document concentrates on the library itself.
 .
 We desire the library to be capable of supporting all JPEG baseline, extended
 sequential, and progressive DCT processes.  Hierarchical processes are not
 supported.
 .
 The library does not support the lossless (spatial) JPEG process.  Lossless
 JPEG shares little or no code with lossy JPEG, and would normally be used
 without the extensive pre- and post-processing provided by this library.
 We feel that lossless JPEG is better handled by a separate library.
 .
 Within these limits, any set of compression parameters allowed by the JPEG
 spec should be readable for decompression.  (We can be more restrictive about
 what formats we can generate.)  Although the system design allows for all
 parameter values, some uncommon settings are not yet implemented and may
 never be; nonintegral sampling ratios are the prime example.  Furthermore,
 we treat 8-bit vs. 12-bit data precision as a compile-time switch, not a
 run-time option, because most machines can store 8-bit pixels much more
 compactly than 12-bit.
 .
 By itself, the library handles only interchange JPEG datastreams --- in
 particular the widely used JFIF file format.  The library can be used by
 surrounding code to process interchange or abbreviated JPEG datastreams that
 are embedded in more complex file formats.  (For example, libtiff uses this
 library to implement JPEG compression within the TIFF file format.)
 .
 The library includes a substantial amount of code that is not covered by the
 JPEG standard but is necessary for typical applications of JPEG.  These
 functions preprocess the image before JPEG compression or postprocess it after
 decompression.  They include colorspace conversion, downsampling/upsampling,
 and color quantization.  This code can be omitted if not needed.
 .
 A wide range of quality vs. speed tradeoffs are possible in JPEG processing,
 and even more so in decompression postprocessing.  The decompression library
 provides multiple implementations that cover most of the useful tradeoffs,
 ranging from very-high-quality down to fast-preview operation.  On the
 compression side we have generally not provided low-quality choices, since
 compression is normally less time-critical.  It should be understood that the
 low-quality modes may not meet the JPEG standard's accuracy requirements;
 nonetheless, they are useful for viewers.
 .
 *** System overview ***
 .
 The compressor and decompressor are each divided into two main sections:
 the JPEG compressor or decompressor proper, and the preprocessing or
 postprocessing functions.  The interface between these two sections is the
 image data that Rec. ITU-T T.81 | ISO/IEC 10918-1 regards as its input or
 output: this data is in the colorspace to be used for compression, and it is
 downsampled to the sampling factors to be used.  The preprocessing and
 postprocessing steps are responsible for converting a normal image
 representation to or from this form.  (Those few applications that want to deal
 with YCbCr downsampled data can skip the preprocessing or postprocessing step.)
 .
 Looking more closely, the compressor library contains the following main
 elements:
 .
 Preprocessing:
 * Color space conversion (e.g., RGB to YCbCr).
 * Edge expansion and downsampling.  Optionally, this step can do simple
 smoothing --- this is often helpful for low-quality source data.
 JPEG proper:
 * MCU assembly, DCT, quantization.
 * Entropy coding (sequential or progressive, Huffman or arithmetic).
 .
 In addition to these modules we need overall control, marker generation,
 and support code (memory management & error handling).  There is also a
 module responsible for physically writing the output data --- typically
 this is just an interface to fwrite(), but some applications may need to
 do something else with the data.
 .
 The decompressor library contains the following main elements:
 .
 JPEG proper:
 * Entropy decoding (sequential or progressive, Huffman or arithmetic).
 * Dequantization, inverse DCT, MCU disassembly.
 Postprocessing:
 * Upsampling.  Optionally, this step may be able to do more general
 rescaling of the image.
 * Color space conversion (e.g., YCbCr to RGB).  This step may also
 provide gamma adjustment [ currently it does not ].
 * Optional color quantization (e.g., reduction to 256 colors).
 * Optional color precision reduction (e.g., 24-bit to 15-bit color).
 [This feature is not currently implemented.]
 .
 We also need overall control, marker parsing, and a data source module.
 The support code (memory management & error handling) can be shared with
 the compression half of the library.
 .
 There may be several implementations of each of these elements, particularly
 in the decompressor, where a wide range of speed/quality tradeoffs is very
 useful.  It must be understood that some of the best speedups involve
 merging adjacent steps in the pipeline.  For example, upsampling, color space
 conversion, and color quantization might all be done at once when using a
 low-quality ordered-dither technique.  The system architecture is designed to
 allow such merging where appropriate.
 .
 Note: it is convenient to regard edge expansion (padding to block boundaries)
 as a preprocessing/postprocessing function, even though
 Rec. ITU-T T.81 | ISO/IEC 10918-1 includes it in compression/decompression.  We
 do this because downsampling/upsampling can be simplified a little if they work
 on padded data: it's not necessary to have special cases at the right and
 bottom edges.  Therefore the interface buffer is always an integral number of
 blocks wide and high, and we expect compression preprocessing to pad the source
 data properly.  Padding will occur only to the next block (8-sample) boundary.
 In an interleaved-scan situation, additional dummy blocks may be used to fill
 out MCUs, but the MCU assembly and disassembly logic will create or discard
 these blocks internally.  (This is advantageous for speed reasons, since we
 avoid DCTing the dummy blocks.  It also permits a small reduction in file size,
 because the compressor can choose dummy block contents so as to minimize their
 size in compressed form.  Finally, it makes the interface buffer specification
 independent of whether the file is actually interleaved or not.)  Applications
 that wish to deal directly with the downsampled data must provide similar
 buffering and padding for odd-sized images.
 .
 *** Poor man's object-oriented programming ***
 .
 It should be clear by now that we have a lot of quasi-independent processing
 steps, many of which have several possible behaviors.  To avoid cluttering the
 code with lots of switch statements, we use a simple form of object-style
 programming to separate out the different possibilities.
 .
 For example, two different color quantization algorithms could be implemented
 as two separate modules that present the same external interface; at runtime,
 the calling code will access the proper module indirectly through an "object".
 .
 We can get the limited features we need while staying within portable C.
 The basic tool is a function pointer.  An "object" is just a struct
 containing one or more function pointer fields, each of which corresponds to
 a method name in real object-oriented languages.  During initialization we
 fill in the function pointers with references to whichever module we have
 determined we need to use in this run.  Then invocation of the module is done
 by indirecting through a function pointer; on most machines this is no more
 expensive than a switch statement, which would be the only other way of
 making the required run-time choice.  The really significant benefit, of
 course, is keeping the source code clean and well structured.
 .
 We can also arrange to have private storage that varies between different
 implementations of the same kind of object.  We do this by making all the
 module-specific object structs be separately allocated entities, which will
 be accessed via pointers in the master compression or decompression struct.
 The "public" fields or methods for a given kind of object are specified by
 a commonly known struct.  But a module's initialization code can allocate
 a larger struct that contains the common struct as its first member, plus
 additional private fields.  With appropriate pointer casting, the module's
 internal functions can access these private fields.  (For a simple example,
 see jdatadst.c, which implements the external interface specified by struct

 The primary algorithm described there uses 11 multiplies and 29 adds.
 We use their alternate method with 12 multiplies and 32 adds.
 The advantage of this method is that no data path contains more than one
 multiplication; this allows a very simple and accurate implementation in
 scaled fixed-point arithmetic, with a minimal number of shifts.

 This file contains a fast, not so accurate integer implementation of the
 inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
 must also perform dequantization of the input coefficients.
 .
 A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
 on each row (or vice versa, but it's more convenient to emit a row at
 a time).  Direct algorithms are also available, but they are much more
 complex and seem not to be any faster when reduced to code.
 .
 This implementation is based on Arai, Agui, and Nakajima's algorithm for
 scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
 Japanese, but the algorithm is described in the Pennebaker & Mitchell
 JPEG textbook (see REFERENCES section in file README.ijg).  The following
 code is based directly on figure 4-8 in P&M.
 While an 8-point DCT cannot be done in less than 11 multiplies, it is
 possible to arrange the computation so that many of the multiplies are
 simple scalings of the final outputs.  These multiplies can then be
 folded into the multiplications or divisions by the JPEG quantization
 table entries.  The AA&N method leaves only 5 multiplies and 29 adds
 to be done in the DCT itself.
 The primary disadvantage of this method is that with fixed-point math,
 accuracy is lost due to imprecise representation of the scaled
 quantization values.  The smaller the quantization table entry, the less
 precise the scaled value, so this implementation does worse with high-
 quality-setting files than with low-quality ones.

 This file contains the JPEG system-independent memory management
 routines.  This code is usable across a wide variety of machines; most
 of the system dependencies have been isolated in a separate file.
 The major functions provided here are:
 * pool-based allocation and freeing of memory;
 * policy decisions about how to divide available memory among the
 virtual arrays;
 * control logic for swapping virtual arrays between main memory and
 backing storage.
 The separate system-dependent file provides the actual backing-storage
 access code, and it contains the policy decision about how much total
 main memory to use.
 This file is system-dependent in the sense that some of its functions
 are unnecessary in some systems.  For example, if there is enough virtual
 memory so that backing storage will never be used, much of the virtual
 array control logic could be removed.  (Of course, if you have that much
 memory then you shouldn't care about a little bit of unused code...)

 These routines may need modification for non-Unix environments or
 specialized applications.  As they stand, they assume output to
 an ordinary stdio stream.

 This file contains a floating-point implementation of the
 inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
 must also perform dequantization of the input coefficients.
 .
 This implementation should be more accurate than either of the integer
 IDCT implementations.  However, it may not give the same results on all
 machines because of differences in roundoff behavior.  Speed will depend
 on the hardware's floating point capacity.
 .
 A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
 on each row (or vice versa, but it's more convenient to emit a row at
 a time).  Direct algorithms are also available, but they are much more
 complex and seem not to be any faster when reduced to code.
 .
 This implementation is based on Arai, Agui, and Nakajima's algorithm for
 scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
 Japanese, but the algorithm is described in the Pennebaker & Mitchell
 JPEG textbook (see REFERENCES section in file README.ijg).  The following
 code is based directly on figure 4-8 in P&M.
 While an 8-point DCT cannot be done in less than 11 multiplies, it is
 possible to arrange the computation so that many of the multiplies are
 simple scalings of the final outputs.  These multiplies can then be
 folded into the multiplications or divisions by the JPEG quantization
 table entries.  The AA&N method leaves only 5 multiplies and 29 adds
 to be done in the DCT itself.
 The primary disadvantage of this method is that with a fixed-point
 implementation, accuracy is lost due to imprecise representation of the
 scaled quantization values.  However, that problem does not arise if
 we use floating point arithmetic.

 Much of the complexity here has to do with supporting input suspension.
 If the data source module demands suspension, we want to be able to back
 up to the start of the current MCU.  To do this, we copy state variables
 into local working storage, and update them back to the permanent
 storage only upon successful completion of an MCU.

 This file provides a really simple implementation of the system-
 dependent portion of the JPEG memory manager.  This implementation
 assumes that no backing-store files are needed: all required space
 can be obtained from malloc().
 This is very portable in the sense that it'll compile on almost anything,
 but you'd better have lots of main memory (or virtual memory) if you want
 to process big images.

 This file contains inverse-DCT routines that produce reduced-size output:
 either 4x4, 2x2, or 1x1 pixels from an 8x8 DCT block.
 .
 The implementation is based on the Loeffler, Ligtenberg and Moschytz (LL&M)
 algorithm used in jidctint.c.  We simply replace each 8-to-8 1-D IDCT step
 with an 8-to-4 step that produces the four averages of two adjacent outputs
 (or an 8-to-2 step producing two averages of four outputs, for 2x2 output).
 These steps were derived by computing the corresponding values at the end
 of the normal LL&M code, then simplifying as much as possible.
 .
 1x1 is trivial: just take the DC coefficient divided by 8.
 .
 See jidctint.c for additional comments.

 libjpeg-turbo Licenses
 ======================
 .
 libjpeg-turbo is covered by three compatible BSD-style open source licenses:
 .
 - The IJG (Independent JPEG Group) License, which is listed in
   [README.ijg](README.ijg)
 .
   This license applies to the libjpeg API library and associated programs
   (any code inherited from libjpeg, and any modifications to that code.)
 .
 - The Modified (3-clause) BSD License, which is listed below
 .
   This license covers the TurboJPEG API library and associated programs, as
   well as the build system.
 .
 - The [zlib License](https://opensource.org/licenses/Zlib)
 .
   This license is a subset of the other two, and it covers the libjpeg-turbo
   SIMD extensions.
 .
 .
 Complying with the libjpeg-turbo Licenses
 =========================================
 .
 This section provides a roll-up of the libjpeg-turbo licensing terms, to the
 best of our understanding.
 .
 1.  If you are distributing a modified version of the libjpeg-turbo source,
     then:
 .
     1.  You cannot alter or remove any existing copyright or license notices
         from the source.
 .
         **Origin**
         - Clause 1 of the IJG License
         - Clause 1 of the Modified BSD License
         - Clauses 1 and 3 of the zlib License
 .
     2.  You must add your own copyright notice to the header of each source
         file you modified, so others can tell that you modified that file (if
         there is not an existing copyright header in that file, then you can
         simply add a notice stating that you modified the file.)
 .
         **Origin**
         - Clause 1 of the IJG License
         - Clause 2 of the zlib License
 .
     3.  You must include the IJG README file, and you must not alter any of the
         copyright or license text in that file.
 .
         **Origin**
         - Clause 1 of the IJG License
 .
 2.  If you are distributing only libjpeg-turbo binaries without the source, or
     if you are distributing an application that statically links with
     libjpeg-turbo, then:
 .
     1.  Your product documentation must include a message stating:
 .
         This software is based in part on the work of the Independent JPEG
         Group.
 .
         **Origin**
         - Clause 2 of the IJG license
 .
     2.  If your binary distribution includes or uses the TurboJPEG API, then
         your product documentation must include the text of the Modified BSD
         License (see below.)
 .
         **Origin**
         - Clause 2 of the Modified BSD License
 .
 3.  You cannot use the name of the IJG or The libjpeg-turbo Project or the
     contributors thereof in advertising, publicity, etc.
 .
     **Origin**
     - IJG License
     - Clause 3 of the Modified BSD License
 .
 4.  The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
     free of defects, nor do we accept any liability for undesirable
     consequences resulting from your use of the software.
 .
     **Origin**
     - IJG License
     - Modified BSD License
     - zlib License
 .
 .

 Why Three Licenses?
 ===================
 .
 The zlib License could have been used instead of the Modified (3-clause) BSD
 License, and since the IJG License effectively subsumes the distribution
 conditions of the zlib License, this would have effectively placed
 libjpeg-turbo binary distributions under the IJG License.  However, the IJG
 License specifically refers to the Independent JPEG Group and does not extend
 attribution and endorsement protections to other entities.  Thus, it was
 desirable to choose a license that granted us the same protections for new code
 that were granted to the IJG for code derived from their software.
