Planisphere > Off-line Usage

Off-line Usage

The original desktop application has been replaced with a web one and the former is not available any more. This fact sometimes makes those users with the limited internet connection sad. Without an internet access the current web application seems to be useless. But it isn't!

The entire browser window consist of a single interactive SVG file. It can be saved to a local disk like any other image and later opened directly without any internet connection.

The only limitation is a disabled button functionality. My recommendation is obvious. Change all the necessary settings before saving this SVG file locally. In this case you get a snapshot which doesn't require any further tweaking so it can be used completely off-line.


Ctrl+S and choose the complete HTML page.

Internet Explorer

In Internet Exporer the main graphics is not the part of resources when the complete HTML page is saved. It is necessary to click the right mouse button somewhere to the graphics and from the context menu select Save Image As...


In Chrome there is no straightforward way to save the main graphics locally, see known issues.
