Functions

Click and drag the mouse to pan around the map.

Press "E" to export an image of the full worldmap. In the original source, it was saved as a raw RGB image and the image dimensions was in the file name. If you use my fork it will be exported to PNG for you.

Loading Data

The client attempts to load the latest worldmap.jag archive. If the applet is running as a frame, it will load it locally from the working directory as "worldmap.jag" Otherwise, it will download from an HTTP server (the codebase of the Applet).

When downloading remotely the URL it loads is "worldmap" + sha + ".jag", where sha is half of the SHA signature represented as bytes, and concatenated:

for (int i = 0; i < 10; i++) {
    sha = sha + Signature.sha[k];
}
