Someone somewhere at DB has written a QR code generator that outputs QR codes as HTML tables. I'm not sure if I should be impressed or horrified.
@cato that’s honestly not the worst idea. Easily supports ancient devices that don’t do svg properly yet, is natively scalable, and probably even saves some data over anything except svg where you put the entire code into one big chonky path data.
@jaseg @cato A 1-bit bitmap or even png with a 1:1 pixel mapping would be even more compact, wouldn't it? It would, however, come with the potential issue of browsers trying to be smart about the upscaling and ruining the pattern in the process
@mart_w @cato exactly that upscaling is only properly supported on fairly recent browsers
