Create a custom ptviewer jar file
Sometimes the simple way by showing your panoramas using the PTViewer Java applet leads to problems, e.g. firewalls at the client side disallow a .jar file to load other files. Then your panoramic won't show at all. Another reason to create custom PTViewer jar files might be the need to include a subset of classes to enable special functions and at the same time don't use the full featured applet with a bigger file size.
This article will try to explain for users of different platforms how to build such a jar step by step. A jar is basically a zip archive with a certain structure of elements. Feel free to edit and improve this page.
Elements that can be packed in a jar
- panoramic image in equirectangular projection as jpg
- a small preview image that is shown while the panoramic image is loaded and decompressed
- what else?
