Project Modules

There are no modules declared in this project.

js-wmf

Processor for Windows MetaFile (WMF) files in JS (for the browser and nodejs).

Installation

With npm:

$ npm install wmf

In the browser:

<script src="wmf.js"></script>

The browser exposes a variable WMF.

Usage

The data argument is expected to be an ArrayBuffer, Uint8Array or Buffer

• WMF.image_size(data) extracts the image offset and extents, returns an Array [width, height] where both metrics are measured in pixels.

• WMF.draw_canvas(data, canvas) parses the WMF and draws to a Canvas.

Notes

• The library assumes the global ImageData is available. For nodejs-powered canvas implementations, a shim must be exposed as a global. Using the canvas npm package:

const { createImageData } = require("canvas");
global.ImageData = createImageData;

• OffscreenCanvas in Chrome and some other Canvas implementations require the dimensions in the constructor:

const size = WMF.image_size(data);
const canvas = new OffscreenCanvas(size[0], size[1]);

Examples

Browser Fetch into canvas (click to show)

// assume `canvas` is a DOM element
(async() => {
  const res = await fetch("url/for/image.wmf");
  const ab = await res.arrayBuffer();
  WMF.draw_canvas(ab, document.getElementById("canvas"));
})();

NodeJS (using `canvas` npm module) (click to show)

const { createCanvas, createImageData } = require("canvas");
global.ImageData = createImageData;

const size = WMF.image_size(data);
const canvas = createCanvas(size[0], size[1]);
WMF.draw_canvas(data, canvas);
