documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# js-wmf
Processor for Windows MetaFile (WMF) files in JS (for the browser and nodejs).
## Installation
With [npm](https://www.npmjs.org/package/wmf):
```bash
$ npm install wmf
```
In the browser:
```html
<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:
```js
const { createImageData } = require("canvas");
global.ImageData = createImageData;
```
- `OffscreenCanvas` in Chrome and some other Canvas implementations require
the dimensions in the constructor:
```js
const size = WMF.image_size(data);
const canvas = new OffscreenCanvas(size[0], size[1]);
```
## Examples
<details>
<summary><b>Browser Fetch into canvas</b> (click to show)</summary>
```js
// 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"));
})();
```
</details>
<details>
<summary><b>NodeJS (using `canvas` npm module)</b> (click to show)</summary>
```js
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);
```
</details>
