Troubleshooting the FRAME command

Explanation:

The implementation of the FRAME command in Ferret is quite different when Ferret is initiated with "ferret -gif" versus when it is initiated with graphics viewed on an X DISPLAY.

With the X DISPLAY, the FRAME command has to download the current bitmap from the X DISPLAY. On some X servers this will work correctly only if the DISPLAY is pseudo-color. In the Hummingbird eXceed X server under MS Windows, for example, you need in the Xconfig program to set Video to

        ServerVisual: PseudoColor

If you are communicating over an asymmetric connection between your X DISPLAY server and your computer, you may notice that the FRAME command is slow. This is probably a result of the upstream bandwidth limitations of the connection.

In most cases, if the FRAME command will not function to your X DISPLAY, you can fall back on "ferret -gif" to obtain GIF output.

If you are running WebFerret, then you need not use the FRAME command. The output graphics that you see in your browser are actually the result of the Ferret FRAME command, and saving the resulting image with your browser controls is equivalent.
