Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

exif-orientation-image

stable

Properly displays an image via canvas based on the exif orientation data. Uses exif-orientation.

Install

npm install exif-orientation-image --save

Example

The following example reacts to the onChange event of a file upload html input

var getOrientedImage = require('exif-orientation-image');

fileUpload.addEventListener('change',function(e) {
  var file = e.target.files[0];
  getOrientedImage(file,function(err,canvas) {
    if (!err) {
      document.body.appendChild(canvas);
    }
  });
});

Usage

NPM

getOrientedImage(file,callback)

file A file object from a file upload html input
callback A function to be called once the image is rendered in its proper position. The callback is passed 2 arguments (err,canvas). If err is undefined, canvas will be an HTML canvas element with the correctly oriented image, otherwise err will be an Error object with the message of the error.

orientation.translate(image,orientation,options)

image A loaded html image element
orientation Orientation object returned from exif-orientation. Contains scale.x, scale.y, and rotation. Rotation is a number in degrees, scale.x and scale.y are numbers.
options Custom options, right now the only options are width and height which determines the size of the returned canvas. It will use the image dimensions if not provided.

orientation.orientation()

Exposes the exif-orientation function in case you want to handle that manually.
