png2linuxlogo takes an 80x80 color-mapped
(palette-based) PNG of 223 or fewer colors
and converts it to a header file suitable for
inclusion in the Linux kernel as the full-color
boot logo. It does not modify the 16-color or
black-and-white boot logos. This allows
standard image editing tools such as the GIMP
or XPaint to be used to create Linux boot
logos. It works with 2.2 and 2.4 kernels.
