I don’t believe I’ve ever seen shape utilized in generated ASCII art
Ah, someone’s never seen 8088 Corruption. The encoder was a brute-force comparison of source pixels with downscaled / blended characters in CGA’s few available colors.
… wait, AAlib definitely uses shape. Is the author just new to ASCII art?
Killer effort, regardless.
I was kind of interested in doing this for Unicode a while back, which has the potential to provide for a lot more possible characters and thus a lot more-accurate renditions. If you don’t care about real-time operation, I suspect that you can do this with off-the-shelf software by just writing a small amount of code to generate an image for each character — a shell script driving ImageMagick could do it — and then feeding it into photomosaic software, like metapixel.
The major limitation is that unless you’re just interested in doing this for the text-based aesthetic and are actually rendering and presenting an image to the end user — think something like Effulgence RPG, Warsim, Armoured Commander II, Armoured Commander, Cogmind, SanctuaryRPG, Cataclysm: Dark Days Ahead, Stone Story RPG, Roots of Harmony, and so forth — you can’t control the font that the thing is rendered in on the end user’s computer. And the accuracy of the rendering degrades the more the typeface used on an end user’s computer differs from your own.
It’d probably be possible to build some kind of system that does take into account the differences for different typefaces, scores characters higher based on checking for character similarity across different typefaces.
Note that there are also at least two existing libraries out there — what I can think of off the top of my head — that will do image-to-ASCII conversion — aalib and libcaca, the latter of which has color support. I also posted a tiny program some time back to generate images using the colored Unicode tiles, and I imagine that someone out there probably has a website that does the same thing.
I apparently actually did two of these on different occasions, using different, restricted Unicode character ranges (ones that only look at the value of the character as a whole, no subpixel rendering). Can’t find the (newer) color one, but the black-and-white one:
