Tweaking the boot animation
Jump to navigation

The boot animation code lives in the bootanim rpm, and it uses the rhgb-client hooks in the initscripts. There are 27 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/frame26.565. They are in the raw framebuffer format. You can convert a PNG with the command:
pngtopnm frame00.png | ./ppmto565.py > frame00.565
using the ppmto565.py script and the pngtopnm tool in the netpbm-progs package:
# yum install netpbm-progs
The 565 files are raw bitmap data and they look large, but they compress exceedingly 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.
