Image scaling with Java can be surprisingly complicated - I ran into lots of reproducable JVM crashes when doing batch processing, which are not related to your bug though. In the end I ended up using the external command line tool 'convert' from ImageMagick, available for the relevant platforms. Simply call it with Runtime.exec(.) and the appropriate parameters. Might be even faster than a real Java solution, but this is certainly not a good solution for all apps.
使用Java进行图像缩放可能会非常复杂 - 在进行批处理时遇到了大量可重现的JVM崩溃,但这与您的bug无关。最后,我最终使用ImageMagick的外部命令行工具'convert',可用于相关平台。只需使用Runtime.exec(。)和相应的参数调用它。可能比真正的Java解决方案更快,但这对所有应用程序来说肯定不是一个好的解决方案。

You might want to use the Java Advanced Imaging (JAI) API. An example of how to scale an image using JAI can be found here.
