The current version of Panoply is 2.6.1, released 2008-07-21.
Panoply requires a computer with a Java 5 runtime environment, or better, installed.
In addition to the map overlays (continent masks and outlines) included in the Panoply application distribution, there are a dozen other overlays available for separate download.
For additional scale colorbar palettes, the cpt-city website includes many CPT format files which are compatible with Panoply.
The Panoply package for Windows comes as a ZIP archive. You must manually extract this archive. Some versions of Windows allow you to run programs from a zipped archive without extraction, but if you try that with Panoply, it won't work.
The Panoply archive contains a folder called PanoplyJ which holds the following items:
The folder called "jars" must remain in the same location as the Panoply.exe application. Also, all .jar files in the jars folder must remain there. If you move or remove that folder or any of its contents, Panoply will not work.
To run Panoply, just double-click on the Panoply.exe application.
You must extract Panoply from the ZIP archive before you try to run it. If you simply open the ZIP file and then double-click on the Panoply icon, you will get a class-loader error because it cannot access some files.
If you find that after download and installation, Panoply for Windows won't start, a possible reason might be that you don't have a Java Runtime Engine (JRE) installed on your computer. To check for this, use the Sun utility that looks for Java on your desktop and automatically downloads it if necessary. Go to the Java.com website and click on the "Free Download" button.
Note: It is possible to have a Java plugin enabled in your web browser which allows you to run applets, but not have a JRE installed which allows you to run Java applications.
