Drawing images on physical floppies using magnetic flux
fluxfox png2disk writes PNG images to floppy disks with fluxfox.
Such images are invisible to the naked eye, but will appear when opened in a tool that produces a floppy disk surface visualization.
Input images should be 32-bit, RGBA PNGs. Only the red channel is sampled, so convert any source image to grayscale in your editor, or examine the red channel in isolation to make sure it looks correct.
Known issues
This is essentially a hack project, and I’m surprised it even works at all, so please keep the production quality of this tool in perspective. The renderer is extremely inefficient, and there’s lots of overdraw to the disk image that could be avoided.
This utility inherits all the bugs present in fluxfox, which is still in heavy development. There are known issues with the MFI and other flux-format importers.
It’s similar to LightScribe on CDs but using flux on Floppies.
