nf-photo-collage

nf-photo-collage

Combines several images into a photo collage.

This is slightly restructured version of original photo-collage repo. It is also using RectangleEquals fork so it is using Canvas v2.

Changes

• Removed header and support for adding text
• Add support for adding image as background
• Add typings (index.d.ts)

Installation

yarn add nf-photo-collage

This library depends on node-canvas (v2), which may require additional setup. See their installation page for details.

Usage

import createCollage from "nf-photo-collage";

const options = {
  sources: [
    imageBufferObject, // source can be a buffer of jpg/png data
    canvasObject, // source can be a canvas object
    "http://myurl.com/image.jpg", // source can be a url string
    "https://myurl.com/image.jpg", // https/ftp is ok too.
    "./localfile.png", // source can be a relative file path
    "~/photos/file.png" // source can be an absolute file path
  ],
  width: 3, // number of images per row
  height: 2, // number of images per column
  imageWidth: 350, // width of each image
  imageHeight: 250, // height of each image
  // backgroundColor: "#cccccc", // optional, defaults to #eeeeee.
  backgroundImage: "./localfile.png" // same formats supported as source
  spacing: 2, // optional: pixels between each image
};

createCollage(options)
  .then((canvas) => {
    const src = canvas.jpegStream();
    const dest = fs.createWriteStream("myFile");
    src.pipe(dest);
  });
