Display overlay kernel mod questions - 07/06/2001 16:56

Hopefully Kim or Kit can answer some of these questions I have.

I am trying to make a basic program to overlay a 16x16 graphic on the screen, and I'd like to put it over on the bottom right of the screen. What do I need to do to say "overlay in this specific space", or is this possible right now. I tried Kim's specific random gibberish code, and I thought it was going to take up the entire bottom of the screen, but instead it took up what appears to be the bottom 8 rows and only half way across. Is that normal? (I have Kit's overlay patch installed, is it different then Kim's?)

Thanks

Yes, it is different and only intended for easy used with timed. I am working on a more generic overlay that will allow you to specify coordinates and what type of overlay you want to do.

Overlay types :

1. Overwrite all pixels in region.
2. Only overwrite pixels that aren't empty in our overlay (so it leaves the stuff behind it).

One of the uses I was thinking of was reading the current fid from /dev/empeg_state and bouncing a band logo around the screen during the first x seconds of a song.

I'll let you know when I get a chance to do this. Otherwise you are stuck hacking up the current patch on your own =].

I'll probably just wait for your next version of it, since this is only part of the project I'm working on right now.
