The boot animation code lives in the bootanim rpm, and it uses the rhgb-client hooks in the initscripts. There are 26 frames in the boot animation, fixed by the number of steps in the initscripts.
The frames live in /usr/share/boot-anim/frame00.565 to /usr/share/boot-anim/frame25.565. They are in the raw framebuffer format. You can convert a PNG with the command:
pngtopnm frame00.png | ./ppmto565.py -z -o frame00.565
using the ppmto565.py script and the pngtopnm tool in the netpbm-progs package:
# yum install netpbm-progs
If you are targetting a release prior to 8.2, you should omit the '-z' option. The resulting files are raw bitmap data and look large, but they compress well onto jffs2 if the images are simple.
The bootanim code lives in the act-gui package in git on dev; talk to cscott if you want changes pulled upstream.
