IMAG

Recently it occurred to me that OpenLP is able to do basic IMAG pretty easily.  VLC can display a webcam stream, so running VLC behind OpenLP with a transparent background theme would be a cheap IMAG system. OpenLP can display text over the webcam video, but would a"lower third" graphic be possible?  It doesn't appear you can apply a theme to an image, so that you could have an image that only takes up a sliver on the bottom of the screen and the rest has a transparent background.  And OpenLP doesn't appear to support gif's featuring transparent portions -- it just displays it as black.

So, am I missing a clever solution to this?  Could I do IMAG with lower thirds like the big boys do with nothing more than a webcam and along usb cable to connect it to the 'puter?  Thanks!

Have you had a look at the formatting tags? It might not be exactly what you're looking for, but it might be a good enough workaround.

Yes!!!  That did work!  Created a lower third graphic that is the same width as the screen, added the formatting tag:

<img src="lower-third.jpg" width="1920px" style="opacity:0.75;">

And then created a custom slide featuring just that formatting tag.  Applied a transparent background to the custom slide, and it turned out exactly like I wanted it!  Thanks so much for the great suggestion!
