Command line options

Night Vision can be invoked at the command line by typing:

    java -jar nvj.jar [options]
or
    java -cp nvj.jar nvj.Nvj [options]

where [options] (which of course are optional) can be:
/swapmouse Swaps the left and right mouse buttons. Normally the right mouse button is used for identifying an object, and the left mouse button is used for centering and zooming (unless other software has pre-swapped the mouse buttons). This option swaps the buttons.
/noantialias Cancels text smoothing (antialiasing), which is normally not desired, but does speed up the program slightly. It is included because one of the Java environments this program was tested on did not handle antialiasing correctly.
/shadehorizon Replaces the on-screen horizon cross-hatching with shading.

A '-' can be used in place of the '/'. Options are not case sensitive. However, the other parts of the line (some or all, depending on your operating system) are case sensitive.

These command line options can also be used if Night Vision was downloaded into your computer as a self-installing package (i.e. from a web link). In this case the properties for the icon that invokes the program (normally by double-clicking with the left mouse button) must be modified. For Windows XP this would mean clicking on the icon with the right mouse button and selecting "Properties" from the pop-up menu to bring up the Properties window for that icon. The desired option above would be appended to the "Target" line under the "Shortcut" tab.
