The POW Options Menu

1. Change Background Color will bring up a dialog box with color sliders. Play with the sliders until you get a color you like.
2. Resize Main Window on Expand: If this box is checked, POW will get bigger or smaller (as far as possible) whenever you change the objects in the main POW window, so as to show you everything currently displayed in the main POW window without scrolling.
3. Set GUI Position: POW's "GUI" consists of the 3 pixel readouts, the Scopebox, and the Zoom In/Out buttons usually located at the top of the window. This menu item allows you to move these to any side of the window or turn them off altogether.
4. Set Scopebox Size: The associated submenu allows one to alter the size of the scopebox -- the window showing a small overview of the current graph -- or hide it altogether.
5. Grid Line Options: You can toggle the grid on or off and choose dashed and colored grid styles for the currently selected graph. More options are available from the Edit Graphs dialog box.
6. Main Cursor Shape: You can choose from a few standard X cursors for the form your Mouse cursor will assume in the main and scope windows.
7. Tick Labels: You may choose decimal or Base 60/degree (WCS) formats for the axis labels on your graphs and for what shows up in the Coordinate tracker. "Base 60" axes only apply to graphs which contain images or curves with WCS coordinate information.
8. Set Default Options: From the resulting dialog box one can control the default display options for graphs. See Default Options for details.
9. Save Current Settings will create a file, recording your current choices for the appearance of POW and the current graph and making them the new default options (see preceding item). The current image and first curve (if either exists) in the selected graph will be used for the new default curve and image options. (Note: On unix machines the created file is at ~/.powrc; on Windows it is c:\fv\lib\fv\fv.ini; and on MacOS it is "pow Preferences" in your System's Preferences folder.)
