Hi everyone,
I maintain a few (commercial) live distributions and have to fulfil the
need of a few customers for a nice graphical boot splash. Unfortunately
busybox' fbsplash was too unflexible, so I added a bit more configurability:
* Specify a background color which is used to flood the whole screen
before drawing the image and the progress bar
* Specify an x and y offset of the ppm image
* Specify an x or y offset larger than the respective screen size to
move the image to the right or bottom edge of the screen (or bottom
right corner)
The attached patch just re-uses functions already in fbsplash.c and
introduces five more config options, this should result in the same size
of the busybox binary. Even if these config options are not set, the
screen is blanked all black before painting the splash, which might be
desired in most cases (and usually is done by using fullscreen images).
With the patch I am able to calculate the position of logo and progress
bar by a script before invoking fbsplash and do not have to add a splash
for each and every screen resolution. Initially I was thinking about
adding more options: color of progess bar and the posibility to specify
a gradient, but this might have enlarged the binary which is not desirable.
If you find the patch useful it would be nice you added it.
Yours,
Mattias
