changing color background into jitter lcd

October 1, 2010 | 6:29 am

Hello there
I’d like to realize an apparently simple goal using max/jitter lcd: drawing shapes into it with mouse while changing the background color continuosly via RGB parameters. It seemed to be easy by sending the brgb message, but I realized that the background color changes only when the lcd receives the clear/reset message, while of course this erase what I draw. Any suggestion?

Repeat the current Drawings by retriggering the draw command e.g. frameoval 20 20 50 50, each time you send a new background colour.

Or, if you use alpha masking, you can use anything you want for the background (a single color, an image, a movie), and overlay the jit.lcd contents on top of that.

thanks a lot too :)

how could it works if I want to mix 4 different image with the original movie source?

In my case, I’m firing subtitles synchronized.
and I need more than one subtitles at a time.

alphablend can be use I guess

any ideas ?
