xmatrix boot animation topic




Hello, Android modders. I recently made a new boot animation with jwz's XScreenSaver's xmatrix.

You can see it on Youtube (/watch?v=P9SvdZGFn9s -- sorry, I'm a n00b and can't post links here yet), but really it just looks like the screensaver. The zip is too big to attach here (64MB), but most of you will want to make your own at some other resolution anyway. The point of this post is to share the tool I made to create the animation.

Rather than futz with video capture of the screen (an extra pain since my screen is too small), I hacked it to output to pixmap files directly. That code is on github at
/sethoscope/xmatrix-dumper

You'll need to grab the XScreenSaver source, clobber xmatrix.c with this one, and build it. My command line looked like this:

./xmatrix -no-knock-knock -no-trace -width 1200 -height 1920 -outfile /tmp/anim/%03d.xpm

It creates a blank window, which is useful for entering commands. I hit '0' to drain around 150 frames in, then killed it manually when I guessed it had probably finished.
