4.16 Still Image Display
Still images can be loaded when the
standard Windows interface or
screen is selected. To load an image,
select the Load option from the
Display menu. The dialog box
displays two list boxes, one to select
the directory or disk drive, the other
to display image files available in the
current directory. A file is selected
by double-clicking on the file name
in the list box, typing the name into
an edit box, or selecting the file
through the list box and clicking on
the OK button. The Cancel button is
provided to abort the file load. The
file format is automatically detected.
The following file types can be
loaded:
a. Windows device-independent
bitmap 24-bit RGB, 8-bit, and
4-bit
b.Targa 32-, 24-, and 16-bit RGB

above.
4.17 Print Captured Images
To print captured images, select the
Print option from the floating menu
or from the Display menu of the
menu bar. This brings up the Print
dialog box supported by the default
printer. If no default printer is
selected, an error message is
displayed.
4.18 Freeze/Unfreeze Video
Video can be frozen or unfrozen
through the Freeze/Unfreeze
option in the floating menu or in
the Display menu in the menu bar.
If live video is frozen and the TV
Board style is changed to cabinet,
the frozen video is unfrozen. This is
done to prevent uninitialized parts
of the video buffer from being
exposed.

When resizing the video window, the
aspect ratio can be forced to 4:3 by
selecting the Proportional option
in the Scale menu option in the
floating menu or in the Display
menu of the menu bar. Selecting
Stretch instead of Proportional
allows the user to arbitrarily size
the video window (any aspect ratio
is allowed).
