netpbm2osbadgeicons

Hey you! Yes, you! Do you have an Apple PowerMac G5? Would you like to customise the icons that are displayed when you open the boot manager by holding your Alt / Option key? And are you not afraid of compiling software, using the terminal, and messing with your boot files at your own risk? Then this project might be for you! :)

For example photos of conversions, check the wiki on GitHub.

Usage

netpbm2osbadgeicons primary.<ppm|pgm|pbm|...> [<secondary.<ppm|pgm|pbm|...>|"none"> [<alphamask.<pgm|pbm>|"none">]]

For example:

netpbm2osbadgeicons /home/puna/coolimage.ppm
netpbm2osbadgeicons /home/puna/coolimage.ppm /home/puna/differentimage.ppm
netpbm2osbadgeicons /home/puna/coolimage.ppm /home/puna/differentimage.ppm /home/puna/alphamask.pbm

netpbm2osbadgeicons /dev/shm/smiley.pgm none /dev/shm/smiley-alpha.pgm

The resulting data for the <OS-BADGE-ICONS> in your tbxi-blessed bootinfo file will be printed to stdout.

For example:

$ netpbm2osbadgeicons ./tests/small.pgm

Notes

• Greyscale rasters may be used for the alpha mask, but might not be fully respected by your hardware. On my G5, 0 is fully transparent, anything >0 is fully visible. If you run into hardware that does support partial transparency in the boot manager, please let me know!
