+1,67 @@ +1.1.90 (1.2 beta1) +================== + +[1] Added a JNI wrapper for TurboJPEG/OSS. See java/README for more details. + +[2] TurboJPEG/OSS can now scale down images during decompression. + +[3] Added SIMD routines for RGB-to-grayscale color conversion, which +significantly improves the performance of grayscale JPEG compression from an +RGB source image. + +[4] Improved performance for non-x86 machines. + +[5] Added a function to the TurboJPEG API which performs lossless transforms. +This function uses the same back end as jpegtran, but it performs transcoding +entirely in memory and allows multiple transforms and/or crop operations to be +batched together, so the source coefficients only need to be read once. This +is useful when generating image tiles from a single source JPEG. + +[6] Modified jpgtest to benchmark the new scaled decompression and lossless +transform features in TurboJPEG/OSS. + +[7] Added support for 4:4:0 (transposed 4:2:2) subsampling in TurboJPEG, which +was necessary in order for it to read 4:2:2 JPEG files that had been losslessly +transposed or rotated 90 degrees. + +[8] All legacy VirtualGL code has been re-factored, and this has allowed +libjpeg-turbo, in its entirety, to be re-licensed under a BSD-style license. + +[9] libjpeg-turbo can now be built with YASM. + +[10] Added SIMD-accelerated fast integer inverse DCT and YCbCr-to-RGB color +conversion routines to accelerate JPEG decoding on ARM Linux and iOS platforms +that have NEON instructions. + +[11] Refactored the TurboJPEG C API so that it uses pixel formats to define the +size and component order of the uncompressed source/destination images as well +as uses the libjpeg memory source and destination managers. The latter allows +the TurboJPEG compressor to grow the JPEG buffer as necessary. + +[12] Eliminated errors in the output of jpegtran on Windows that occurred when +the application was invoked using I/O redirection +(jpegtran <input.jpg >output.jpg). + +[13] The inclusion of libjpeg v7 and v8 emulation as well as arithmetic coding +support in libjpeg-turbo v1.1.0 introduced several new error constants in +jerror.h, and these were mistakenly enabled for all emulation modes, causing +the error enum in libjpeg-turbo to sometimes have different values than the +same enum in libjpeg. This represents an ABI incompatibility, and it caused +problems with rare applications that took specific action based on a particular +error value. The fix was to include the new error constants conditionally +based on whether libjpeg v7 or v8 emulation was enabled. + +[14] Fixed an issue whereby Windows applications that used libjpeg-turbo would +fail to compile if the Windows system headers were included before jpeglib.h. +This issue was caused by a conflict in the definition of the INT32 type. + +[15] Implemented a more efficient version of TJBUFSIZE() which computes a +worst-case JPEG size based on the level of chrominance subsampling. + +[16] Fixed 32-bit supplementary package for amd64 Debian systems which was +broken by enhancements to the packaging system in 1.1. + + 1.1.1 ===== diff --git a/Makefile.am b/Makefile.am index 005f040..f384eab 100644 --- a/Makefile.am +++ b/Makefile.am @@ -34,19 +34,35 @@ libjpeg_la_SOURCES += jdarith.c endif -libturbojpeg_la_SOURCES = $(libjpeg_la_SOURCES) turbojpegl.c turbojpeg.h \ -

Also, each line of each plane in the output image is padded to 4 bytes.

allows the TurboJPEG/OSS dynamic library to be loaded and used directly +from Java applications. The Java front end for this is defined in several +classes located under org/libjpegturbo/turbojpeg. The source code for these +Java classes is licensed under a BSD-style license, so the files can be +incorporated directly into both open source and proprietary projects without +restriction. A Java archive (JAR) file containing these classes is also +shipped with the "official" distribution packages of libjpeg-turbo. + +TJExample.java, which should also be located in the same directory as this +README file, demonstrates how to use the TurboJPEG/OSS Java front end to +compress and decompress JPEG images in memory. + + +Performance Pitfalls +-------------------- + +The TurboJPEG Java front end defines several convenience methods which can +allocate image buffers or instantiate classes to hold the result of compress, +decompress, or transform operations. However, if you use these methods, then +be mindful of the amount of new data you are creating on the heap. It may be +necessary to manually invoke the garbage collector to prevent heap exhaustion +or to prevent performance degradation. Background garbage collection can kill +performance, particularly in a multi-threaded environment (Java pauses all +threads when the GC runs.) + +The Java front end always gives you the option of pre-allocating your own +source and destination buffers, which allows you to re-use these buffers for +compressing/decompressing multiple images. If the image sequence you are +compressing or decompressing consists of images of the same size, then +pre-allocating the buffers is recommended. + + +Note for OS X users +------------------- + +/usr/lib, the directory under which libturbojpeg.dylib is installed on Mac +systems, is not part of the normal Java library path. Thus, when running a +Java application that uses TurboJPEG/OSS on Mac systems, you will need to pass +an argument of -Djava.library.path=/usr/lib to java. + + +Note for Solaris users +---------------------- + +/opt/libjpeg-turbo/lib, the directory under which libturbojpeg.so is installed +on Solaris systems, is not part of the normal Java library path. Thus, when +running a Java application that uses TurboJPEG/OSS on Solaris systems, you will +need to pass an argument of -Djava.library.path=/opt/libjpeg-turbo/lib to java. +If using a 64-bit data model, then instead pass an argument of +-Djava.library.path=/opt/libjpeg-turbo/lib/amd64 to use the 64-bit version of +libturbojpeg.so. diff --git a/java/.svn/text-base/TJExample.java.svn-base b/java/.svn/text-base/TJExample.java.svn-base new file mode 100644 index 0000000..a326c71 --- /dev/null +++ b/java/.svn/text-base/TJExample.java.svn-base @@ -0,0 +1,307 @@ +/* + * Copyright (C)2011 D.

A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE> +<H3> +Index</H3> +<BLOCKQUOTE> +The <A HREF="index-all.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE> +<H3> +Prev/Next</H3> +These links take you to the next or previous class, interface, package, or related page.<H3> +Frames/No Frames</H3> +These links show and hide the HTML frames. All pages are available with or without frames. +<P> +<H3> +Serialized Form</H3> +Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API.

By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. -\f1 \ -\ - -\f0 When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. -\f1 \ -\ - -\f0 To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. -\f1 \ -\ - -\f0 For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. -\f1 \ -\ - -\f0 We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. -\f1 \ -\ - -\f0 To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. -\f1 \ -\page -\f0 \ -Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. -\f1 \ -\ - -\f0 When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. -\f1 \ -\ - -\f0 We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. -\f1 \ -\ - -\f0 For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. -\f1 \ -\ - -\f0 In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. -\f1 \ -\ - -\f0 Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. -\f1 \ -\ - -\f0 The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. -\f1 \ -\page -\f0 \ -\pard\pardeftab720\qc -\cf0 GNU LESSER GENERAL PUBLIC LICENSE\uc0\u8232 TERMS AND CONDITIONS FOR COPYING,\u8232 DISTRIBUTION AND MODIFICATION\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. -\f1 \ -\ - -\f0 The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) -\f1 \ -\ - -\f0 "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. -\f1 \ -\ - -\f0 Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. -\f1 \ - \ - -\f0 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. -\f2 \ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. -\f1 \ -\page -\f0 \ -2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural - -\f0 \cf0 a) The modified work must itself be a software library.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.\ -\pard\pardeftab720\ql\qnatural +\pard\pardeftab720 -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) -\f1 \ -\ - -\f0 These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. -\f1 \ -\ - -\f0 In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. -\f1 \ -\ - -\f0 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. -\f1 \ -\page -\f0 \ -Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 This option is useful when you wish to copy part of the code of the Library into a program that is not a library. -\f1 \ -\ - -\f0 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a -\f1 \ - -\f0 medium customarily used for software interchange. -\f1 \ -\ - -\f0 If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not -\f1 \ - -\f0 compelled to copy the source along with the object code. -\f1 \ -\ - -\f0 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. -\f1 \ -\ - -\f0 However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. -\f1 \ -\ - -\f0 When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. -\f1 \ -\ - -\f0 If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative -\f1 \ - -\f0 work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) -\f1 \ -\ - -\f0 Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. -\f1 \ -\page -\f0 \ -6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: -\f1 \ -\ -\pard\pardeftab720\li720\ri0\ql\qnatural - -\f0 \cf0 a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.)\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. -\f1 \ -\ - -\f0 It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. -\f1 \ -\page -\f0 \ -7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural - -\f0 \cf0 a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -\pard\pardeftab720\li720\ri0\ql\qnatural -\cf0 b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.\ -\pard\pardeftab720\ql\qnatural -\cf0 \ -8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. -\f1 \ -\ - -\f0 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. -\f1 \ -\ - -\f0 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. -\f1 \ -\page -\f0 \ -11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. -\f1 \ -\ - -\f0 It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is -\f1 \ - -\f0 implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. -\f1 \ -\ - -\f0 This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. -\f1 \ -\ - -\f0 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. -\f1 \ -\ - -\f0 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. -\f1 \ -\ - -\f0 Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. -\f1 \ -\page -\f0 \ -14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\qc - -\f0 \cf0 NO WARRANTY\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. -\f1 \ +\f0\fs24 \cf0 Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:\ \ +\pard\tx220\tx720\pardeftab720\li720\fi-720 +\ls1\ilvl0\cf0 {\listtext \'95 }Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.\ +{\listtext \'95 }Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution.\ +{\listtext \'95 }Neither the name of the libjpeg-turbo Project nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.\ \pard\pardeftab720\qc - -\f0 \cf0 END OF TERMS AND CONDITIONS\ -\page \ -How to Apply These Terms to Your New Libraries\ -\pard\pardeftab720\ql\qnatural - -\f1 \cf0 \ -\pard\pardeftab720\ql\qnatural - -\f0 \cf0 If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change.

On such systems, libjpeg-turbo is generally 2-4x as fast - as the unmodified version of libjpeg, all else being equal. libjpeg-turbo - also includes a wrapper library which implements the TurboJPEG API used by - VirtualGL and TurboVNC. - . - libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but - the TigerVNC and VirtualGL projects made numerous enhancements to the codec - in 2009, including improved support for Mac OS X, 64-bit support, support - for 32-bit and big endian pixel formats (RGBX, XBGR, etc.), accelerated - Huffman encoding/decoding, and various bug fixes. The goal was to produce a - fully open source codec that could replace the partially closed source - TurboJPEG/IPP codec used by VirtualGL and TurboVNC. libjpeg-turbo generally - performs in the range of 80-120% of TurboJPEG/IPP. It is faster in some - areas but slower in others. - . - In early 2010, libjpeg-turbo spun off into its own independent project, with - the goal of making high-speed JPEG compression/decompression technology -
