different sizes, the logo is scaled to look the same on the preview
video.
Logos have the following characteristics:


A selectable key color can be specified; all parts of the logo graphic with that color are not drawn
on the video.

video running, you can view your changes interactively. (If your application displays capture video in
real time, then the capture video can be used instead.)
