What is @jimp/plugin-threshold?

@jimp/plugin-threshold is a plugin for the Jimp image processing library that allows you to apply threshold effects to images. This effect converts an image to black and white based on a threshold value, which can be useful for various image processing tasks such as edge detection, binarization, and more.

What are @jimp/plugin-threshold's main functionalities?

Apply Threshold Effect

This feature allows you to apply a threshold effect to an image. The `max` parameter specifies the threshold value. Pixels with a value above this threshold will be set to white, and those below will be set to black.

const Jimp = require('jimp');

Jimp.read('path/to/image.jpg')
  .then(image => {
    image.threshold({ max: 128 })
         .write('path/to/output.jpg');
  })
  .catch(err => {
    console.error(err);
  });
