Hello, There are a couple of benefits to using JAI: - faster image processing; - JAI is still maintained by Sun and has many features not present in JIMI (image tiling, regions of interest, deferred execution, etc.), whereas JIMI is a legacy library; - JAI is an extensible API, so you can add new image processing capabilities or plug in your own implementation, although only the Sun's reference implementation is known to work well at this time; But: - Sun's implementation of JAI is not pure Java (it uses native code on Windows, Solaris and Linux but only for performance enhancements). For example Sun provides no Mac OS implementation, which certainly settles the whole issue against including JAI in <oXygen/>. Some users were able to get JAI to run on Mac OS X by downloading the pure Java version of JAI and then placing the jar files in the proper locations but this is explicitly not supported by Sun and is not accelerated to take advantage of the Macintosh architecture. According to Sun's website their JAI implementation has not yet been certified as 100% pure Java application and Sun and Apple are working on an agreement to make a Mac implementation; - JAI cannot be used with FOP versions older than 0.20.5, because these versions were not compiled with JAI support, so it will not work with <oXygen/> version 2.0.4 which includes FOP 0.20.4 (we plan to include the latest FOP version, that is 0.20.5, in the next release of <oXygen/> but we found some image rendering problems with it). This obviates your second question, Sean. Sorry. Regards, Sorin Sean Wheller wrote:
Hi,
Is there any benefit to using JAI instead of JIMI?
What is the instruction for installing JAI so that Oxygen can use it during FO transforms?
