Video monitor and XView

If the CCD camera is installed on the visible light microscope, you may want to fire up two windows of interest: a video monitor (like a TV screen for the CCD camera), and XView. Type the command

   video

to start up the video monitor and XView.

You can then grab a video picture and save it as a file if you like. The following procedure will let you do this:

1. Get the XView control panel to be visible. It's a window with a title xv controls. If it's been shrunk to an icon, look for the xv icon and click or double-click on it. If you see a window with flying fish and the title xv 3.10a <unregistered>, click on that picture with the right mouse button to get the xv controls window.
2. Click on the grab button, which is at the lower right corner of the xv controls window.
3. Set the delay to be 1 or more seconds in the xv grab window.
4. Click on the border of the video monitor window (title Monitor) to bring it to the front, so that no other windows lay on top of it.
5. You now have two choices:

   Choice 1:

   Click on Grab in the xv grab window. Click in the middle of the video monitor window entitled Monitor.

   Choice 2:

   Click on the AutoGrab button, and immediately move the cursor into the video window.

   XView should eventually give you a new window with the image you snapped.
6. Go to the xv controls menu and click on Save. Pick Full color and GIF as the file type options. Enter a sensible name, such as 16jan96_01.gif

If Grab and AutoGrab just beep at you, then go to the xv 3.10a <unregistered> window, click the right mouse button once to make xv controls disappear, and click the right mouse button again to make xv controls reappear. The Grab and AutoGrab controls should then work.
