Converting an image from RGB to CMYK with Node JS

My printer only work on CMYK colors. And I want to make a telegram bot with node js. I searched on internet to directly transform image color space. But I cannot find.

For python; I find Image.convert(). Its worked for me. My question is that can I make this with an node package?

Solution

  • Use this awesome npm package called Sharp https://github.com/lovell/sharp

    Installation is:

    npm install sharp

    Then your JS is as easy as:

    const sharp = require('sharp');

console.log('Converting...')

sharp('input.jpg')
    .toColourspace('cmyk')
    .toFile('output.jpg')
    .then(() => {
        console.log('Conversion completed!')
});
