The author used flood fill to detect the punched holes in the original image and they manually edited it to produce an unpunched card. Unfortunately, it doesn't type the human-readable text above the column like keypunches did, but I've suggested that improvement. The interactivity is well done!

@thalia@discuss.systems Weird that the space character is just, well space. I didn't know that!
