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/TJExample.java b/java/TJExample.java new file mode 100644 index 0000000..a326c71 --- /dev/null +++ b/java/TJExample.java @@ -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. 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>
