TurboJPEG Java Wrapper
|
||||
======================
|
||||
|
||||
The TurboJPEG shared library can optionally be built with a Java Native
|
||||
Interface wrapper, which allows the 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 Java API to compress and
|
||||
decompress JPEG images in memory.
|
||||
|
||||
|
||||
Performance Pitfalls
|
||||
--------------------
|
||||
|
||||
The TurboJPEG Java API defines several convenience methods that 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 TurboJPEG Java API always gives you the option of pre-allocating your own
|
||||
source and destination buffers, which allows you to re-use those 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.
|
||||
|
||||
|
||||
Installation Directory
|
||||
----------------------
|
||||
|
||||
The TurboJPEG Java Wrapper will look for the TurboJPEG JNI library
|
||||
(libturbojpeg.so, libturbojpeg.jnilib, or turbojpeg.dll) in the system library
|
||||
paths or in any paths specified in LD_LIBRARY_PATH (Un*x), DYLD_LIBRARY_PATH
|
||||
(Mac), or PATH (Windows.) Failing this, on Un*x and Mac systems, the wrapper
|
||||
will look for the JNI library under the library directory configured when
|
||||
libjpeg-turbo was built. If that library directory is
|
||||
/opt/libjpeg-turbo/lib32, then /opt/libjpeg-turbo/lib64 is also searched, and
|
||||
vice versa.
|
||||
|
||||
If you installed the JNI library into another directory, then you will need
|
||||
to pass an argument of -Djava.library.path={path_to_JNI_library} to java, or
|
||||
manipulate LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, or PATH to include the directory
|
||||
containing the JNI library.

How This API Document Is Organized</H1>
|
||||
</CENTER>
|
||||
This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3>
|
||||
Package</H3>
|
||||
<BLOCKQUOTE>
|
||||
|
||||
<P>
|
||||
Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL>
|
||||
<LI>Interfaces (italic)<LI>Classes<LI>Enums<LI>Exceptions<LI>Errors<LI>Annotation Types</UL>
|
||||
</BLOCKQUOTE>
|
||||
<H3>
|
||||
Class/Interface</H3>
|
||||
<BLOCKQUOTE>
|
||||
|
||||
<P>
|
||||
Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL>
|
||||
<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description
|
||||
<P>
|
||||
<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary
|
||||
<P>
|
||||
<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL>
|
||||
Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE>
|
||||
</BLOCKQUOTE>
|
||||
<H3>
|
||||
Annotation Type</H3>
|
||||
<BLOCKQUOTE>
|
||||
|
||||
<P>
|
||||
Each annotation type has its own separate page with the following sections:<UL>
|
||||
<LI>Annotation Type declaration<LI>Annotation Type description<LI>Required Element Summary<LI>Optional Element Summary<LI>Element Detail</UL>
|
||||
</BLOCKQUOTE>
|
||||
</BLOCKQUOTE>
|
||||
<H3>
|
||||
Enum</H3>
|
||||
<BLOCKQUOTE>
|
||||
|
||||
<P>
|
||||
Each enum has its own separate page with the following sections:<UL>
|
||||
<LI>Enum declaration<LI>Enum description<LI>Enum Constant Summary<LI>Enum Constant Detail</UL>
|
||||
</BLOCKQUOTE>
|
||||
<H3>
|
||||
Tree (Class Hierarchy)</H3>
|
||||
<BLOCKQUOTE>
|
||||
There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL>
|
||||
<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL>
|
||||
</BLOCKQUOTE>
|
||||
<H3>
|
||||
Deprecated API</H3>
|
||||
<BLOCKQUOTE>
|
||||
The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. 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. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
|
||||
<P>
|
||||
<H3>
|
||||
Constant Field Values</H3>
|
||||
The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.

||||

<DL>

<DD>Encode the uncompressed source image associated with this compressor

instance and output a YUV planar image to the given destination buffer.
|
||||
This method uses the accelerated color conversion routines in TurboJPEG's
|
||||
underlying codec but does not execute any of the other steps in the JPEG
|
||||
compression process. The Y, U (Cb), and V (Cr) image planes are stored
|
||||
sequentially into the destination buffer, and the size of each plane is
|
||||
determined by the width and height of the source image, as well as the
|
||||
specified padding and level of chrominance subsampling. If the
|
||||
chrominance components are subsampled along the horizontal dimension, then
|
||||
the width of the luminance plane is padded to the nearest multiple of 2 in
|
||||
the output image (same goes for the height of the luminance plane, if the
|
||||
chrominance components are subsampled along the vertical dimension.)
|
||||
<p>
|
||||
NOTE: Technically, the JPEG format uses the YCbCr colorspace, but per the
|
||||
convention of the digital video community, the TurboJPEG API uses "YUV" to
|
||||
refer to an image format consisting of Y, Cb, and Cr image planes.

<DL>
|

<DD>Losslessly transform the JPEG image associated with this transformer
|

instance into one or more JPEG images stored in the given destination
|

buffers. Lossless transforms work by moving the raw coefficients from one
|
||||
JPEG image structure to another without altering the values of the
|
||||
coefficients. While this is typically faster than decompressing the
|
||||
image, transforming it, and re-compressing it, lossless transforms are not
|
||||
free. Each lossless transform requires reading and performing Huffman
|
||||
decoding on all of the coefficients in the source image, regardless of the
|
||||
size of the destination image. Thus, this method provides a means of
|
||||
generating multiple transformed images from the same source or of applying
|
||||
multiple transformations simultaneously, in order to eliminate the need to
|
||||
read the source coefficients multiple times.

||||
* Losslessly transform the JPEG image associated with this transformer
|
||||
* instance into one or more JPEG images stored in the given destination
|
||||
* buffers. Lossless transforms work by moving the raw coefficients from one
|
||||
* JPEG image structure to another without altering the values of the
|
||||
* coefficients. While this is typically faster than decompressing the
|
||||
* image, transforming it, and re-compressing it, lossless transforms are not
|
||||
* free. Each lossless transform requires reading and performing Huffman
|
||||
* decoding on all of the coefficients in the source image, regardless of the
|
||||
* size of the destination image. Thus, this method provides a means of
|
||||
* generating multiple transformed images from the same source or of applying
|
||||
* multiple transformations simultaneously, in order to eliminate the need to
|
||||
* read the source coefficients multiple times.

* @param dstBufs an array of image buffers. <code>dstbufs[i]</code> will
|

* receive a JPEG image that has been transformed using the parameters in
