    Hi-DPI quality

      How do you get the published files to look sharp on retina displays? Even the text looks blurry. Old .swf files were nice and sharp, and same with Edge files. Help!

          I use .SVG instead of PNG / JPG. That seems to upscale properly on Retina / Mobile (as it is vector). Also make your text into .SVG (don't forget to 'create outlines').

            Like for any other images on the web, for retina good looking use doubled sizes.

              The problem with double size images is that they look great on retina screen but will look blurry on non retina screens.


              As Edge doesn't natively support x2 images along side normal images, you have to choose which you prefer. However there is a way of hacking into the published edge.js file to make the browser automatically select retina or non retina images. I did this once before so i'll try and dig out my code and paste it here.

                OK, so this simple piece of code will allow you to use “retina display images” in your Edge Animate project.


                Once you have saved your EA project for the first time open up the HTML file and copy the following code above the line that says <!--Adobe Edge Runtime-->:



                  function getDevicePixelRatio() {

                  if(window.devicePixelRatio === undefined) return 1; // No pixel ratio available. Assume 1:1.

                  return window.devicePixelRatio;


                  if(getDevicePixelRatio() > 1) {

                  var im='imagesRetina/';

                  } else {

                  var im='images/';




                This script checks your display type.


                Next continue as you normally would when building your project placing all your images in the image folder.


                Once you have completed your project, publish it and create a second folder in the published ‘web’ folder called imagesRetina, place all your retina images in here.


                Now open up the yourfile_edge.js file from your published folder, find and delete the following piece of code:


                var im='images/',


                Save the file and test.

                    No worries, if I can find an improvement to the initial script i'll post an update.
