@alxcube/lens-jimp

Lens-Jimp

Jimp driver for @alxcube/lens library.

Installation

npm i jimp @alxcube/lens @alxcube/lens-jimp

Usage

ES module syntax

import { Adapter } from "@alxcube/lens-jimp";
import { distort } from "@alxcube/lens";

const sourceImage = await Adapter.createFromFile("path/to/image.png");
const { image } = await distort(sourceImage, "Arc", [90]);
const jimpInstance = image.getResource();
jimpInstance.write("path/to/result.png");

You can only import "@alxcube/lens-jimp" for side-effect. It will register Jimp adapter factory in Lens, so you can pass Jimp instances to distort() function:

import "@alxcube/lens-jimp"; // Registers Jimp adapter factory in Lens.
import Jimp from "jimp";
import { distort } from "@alxcube/lens";

const sourceImage = await Jimp.read("path/to/image.png");
const { image } = await distort(sourceImage, "Arc", [90]);
const jimpInstance = image.getResource();
jimpInstance.write("path/to/result.png");

CommonJs syntax

const { distort } = require("@alxcube/lens");
const Jimp = require("jimp");
const { Adapter } = require("@alxcube/lens-jimp");

Adapter.createFromFile("path/to/image.png")
  .then((image) => {
    return distort(image, "Arc", [90]);
  })
  .then((result) => result.image.getResource())
  .then((jimp) => {
    return jimp.write("path/to/result.png"); // save result
  });
