| TurboJPEG/OSS JNI Wrapper |
| ========================= |
| |
| TurboJPEG/OSS can optionally be built with a Java Native Interface wrapper, |
| which allows the TurboJPEG/OSS dynamic library to be loaded and used directly |
| from Java applications. The Java front end for this is defined in |
| turbojpeg.java, which should be located in the same directory as this README |
| file. turbojpeg.java is licensed under a BSD-style license, so it can be |
| incorporated directly into both open source and proprietary projects without |
| restriction. |
| |
| 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. |
| |
| javac *.java |
| |
| builds .class files for both the front end and example code. |

| 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. |
