I try code like this, but I get nothing. I don't get an error, but there's no output to the screen.


var art = require("ascii-art")

art.image({
        src: "file:///home/dave/Pictures/nyt.png",
        rows:80,
        cols:80,
        stipple:"#000000",
        posterize: true,
        threshold:40
    }, (err, rendered) => {

      console.log(err,rendered);
    })

If you are compiling from source, you'll need the dependencies from canvas(mostly cairo): https://www.npmjs.com/package/canvas . If not please let me know what type of system/os you are on.

Same issue. Is there any additional documentation to learn how to use this tool for images?

@khrome Does this library work with node > 14 or is it deprecated at this point? I'm using node 16 on a Mac and neither regular terminal or iTerm2 display any images when using:

import art from "ascii-art";
const { Image } = art;

    await Image({
        src: "/Users/admin/images/1.png",
        rows:80,
        cols:80,
        // stipple:"#000000",
        posterize: true,
        threshold:40
    }, (err, rendered) => {

        console.log(err,rendered);
    })

Callback never gets hit, and using a sleep timer to keep the program running doesn't work either.

I found that works if I use uri instead of src. I'm not sure if that's a bug in the code or in the documentation?

khrome commented 11 months ago

Both should work. The library is in the midst of a total rewrite for 3.0, my guess is src is a regression which hasn't been caught. Added to my list to track for the new version.

FWIW the suites pass on node18, so I'd refer to them for usage.

Let me know if you encounter any additional issues. Thanks!
