ASCII art and "ASCII" art


I first had email, and first saw a :-) smiley face in 1990. It was about that time, also, that I was exposed to concrete poetry. Both the smiley and the pictures of words poetry were influential on my mind.

I've had a long lasting love of ASCII art and things near to it since. The first program I saw that could create ASCII art from another image was pbmtoascii from the netpnm package. It worked, but it was kinda disappointing. I had seen, and even made myself, hand drawn ASCII art that was much better than the output of that tool.

Eventually I learned there is a higher quality option to the program.

But that still seemed lack luster to me. About 21 years ago, the date I have in the file is 27 Dec 1999, I wrote my own tool that turns gray scale ("pgm") images instead of bitmap ("pbm") images into ASCII art.

Later I did things like convert ASCII art back into images in various ways. asciiversion2color is not a great program (and didn't even work for me today, because pamarith has been is named pnmarith on this system, a hazard of the netpbm tools being old and reaching different places from different paths, but when I did git it working:

$ pnmscale -w 120 fine300.ppm > fine.ppm
$ asciiversion2color fine.ppm textfine.ppm
pnmarith: promoting second file to PPM
pnmarith: promoting second file to PPM
pnmarith: promoting second file to PPM
HTML version in textfine.ppm.html
$  cjpeg textfine.ppm > textfine.jpg
This is fine, in three color ASCII art

asciiversion2color creates three pbmascii images, one for each RGB channel (in the "ppm" pixmap), converts the ASCII to text-in-image form, then combines the three with a slight offset.

And texttopnm lets you specify an arbitrary tile for each character, as a way of introducing fonts. It has some code for UTF-8 fonts, but I've mostly used it with historic fonts.

$ (echo scale=5; echo 9/14 ) | bc
.64285
$ pnmscale -w 60 fine300.pgm | pnmscale -yscale .64285 > fine60.pgm
$ pgmtoascii fine60.pgm > fine60.txt
$ texttopnm -s .ppm -d font/9x14 fine60.txt 9x14.pgm
$ pnminvert 9x14.pgm |pnmtopng > 9x14.png
This is fine, IBM circa 1981 style

The 9x14 font is the IBM Monochrome Display Adapter hardware font from circa 1981. Quoting Wikipedia:

Each character is rendered in a box of 9×14 pixels, of which 7×11 depicts the character itself and the other pixels provide space between character columns and lines. [...] Each character cell can be set to one of 256 bitmap characters stored in ROM on the card, and this character set cannot be altered from the built-in hardware code page 437. The only way to simulate "graphics" is through ASCII art.

Most recently, I found someone else's code that was created for emulating monochrome bitmap graphics using Braille characters in Unicode in terminal windows. I loved it immediately, and forked it to add a pbmtodots still image converter.

It's no longer ASCII art, by a long strech, but it's very clearly identifiable in a modern text window.
