Jimp: image.threshold is not a function

[SamuelZhaoY]

I tried to install the plugin 'jimp/plugin-threshold', and then I followed the instruction provided by
https://github.com/oliver-moran/jimp/tree/master/packages/plugin-threshold. invoking method of 'image.threshold({ max: 150 });' will simply produce an error:

TypeError: image.threshold is not a function

looking at the docs it is not immediately obvious that you have to use @jimp/custom also! Sorry about that.

Try something like following:

const Jimp = require('jimp')
const threshold = require('@jimp/plugin-threshold')
const configure = require('@jimp/custom')

const MyJimp = configure({ plugins: [threshold] }, Jimp)
// You might be able to just call configure since it modifies the global jimp (I think)
configure({ plugins: [threshold] }, Jimp)

Thanks, I found out the document for this. Yes, the code above works 👍

@hipstersmoothie Thanks! Took me a while to find this, I then found this link:

Would probably be good to link this the “Extra Plugins” section of the readme?
