The #C64 image converter no longer works for me:
c64.superdefault.com/

Perhaps it's because now browsers require https to upload files? Tested on both Firefox and Chrome...

Anyone knows an offline #C64 image converter? It's for... work.

@codewiz When I was searching for one, I ended up instead looking at instructions on how to accomplish that with gimp: reducing resolution and the colours does it. Should also be doable with Imagemagick.

@globalc I'm trying with ImageMagick:

convert bernie-thumb-square.jpg -scale 160x160 -dither FloydSteinberg -remap c64_palette.png out.png

but the result looks too "good" for the #c64:

In part, it's because nobody was doing Floyd–Steinberg dithering back in the day (ImageMagick doesn't have a lot of options).

In part, it's also because the #C64 was constrained to 4 colors per character cell in multicolor mode.

@globalc @root #retrocomputing

@globalc @root Without dithering at all, it also looks wrong (any #C64 artist would have used some dithering):

@codewiz @root
First result looks to me already like from a c64 demo. Maybe shirt sticks out a bit - mastodon cuts that off at the preview of the pic.

@globalc @root I could make an animgif version using 60hz flickering to create intermediate color shades! #c64 #demoscene

@codewiz @root
btw, this reminded me of that quote I got from somewhere, "the whole moon landing was done with less computing power than 2 c64 deliver.."
