o Drag the cross-hair icon in the center of the marquee to relocate it on the screen or
to a different monitor.
o Drag the mouse on any border of the marquee
to scale it up or down. By default, scaling is
constrained to retain a 16:9 marquee aspect.
Hold down Ctrl when dragging to release the
aspect lock. To restore the marquee’s standard
widescreen aspect, simply drag the border again
without the Ctrl key depressed.
o The next Video Source option shown in
the menu is Window. This is a
particularly useful option, as it allows
you to ‘snap’ iVGA to a specific
application window (or child window).
For example, you might designate just the
video player pane on a web browser page or in Skype™ as the source; or perhaps
you might want to snap to the video display pane to an application window.
When you select the Window option in the Video Source menu, a new icon is shown
at right (Figure 191). Click the mouse on this icon, and then drag it to the
application window you want to assign as the source.
The marquee updates as you drag the mouse around the screen from one
application window to another. (Note that it automatically disappears from view
when the control panel is closed.)
Hint: Many application windows actually comprise a number of child windows
grouped together. When you drag the marquee around in Window mode its borders
snap to the current child window, showing what is currently selected.
o Finally, if you have any webcams or similar video input devices connected to the
system, you’ll see these listed below the Window option in the Video Source menu.
