I'd welcome this patch to busybox. We currently maintain a similar patch
that adds a floodfill switch (which just uses the color of the top left
pixel of the image) and a switch for centering the image on screen. Your
patch is a perfect fit for us, as we were planning on adding functionality
to freely position the image on screen too. So if this makes it into
busybox I'd happily throw away our patch.
Cheers,
Simon

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.
I just updated the patch: The calculation for cropping the image was
wrong, the parameter name "IMAGE_WIDTH" proved too long on 32 bit
systems and I added a "NOFILL=1" option. This option allows drawing an
arbitary image to an arbitary position without completely wiping the
framebuffer first. Take a look at the demo script (run with the path to
your busybox binary) as first parameter: The scripts reads the
framebuffer dimensions, creates two config files, paints an image on a
plain background, progress bar and changing icon beneath the progress
bar.
The demo script: http://distfiles.lesslinux.org/fbsplash_demo.tar.gz
The patch is attached.
Yours,
Mattias
