ember-cli-image-transformer

Transform Images for your Ember Application from One Source Image

I hate having to create a bunch of identical images for use as icons and favicon images for my application, so I created this addon to take a single source image and transform it into many images of differing sizes, types, and backgrounds.

It is built using EmberJS and takes advantage of the awesome Sharp library to do the heavy lifting.

Compatibility

• Ember.js v4.8 or above
• Ember CLI v4.8 or above
• Node.js v18 or above

Installation

ember install ember-cli-image-transformer

Usage

Create an ember-cli-image-transformer section in your ember-cli-build.js file with an images array. Each element in the array represents a different set of images to be generated.

module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    'ember-cli-image-transformer': {
      images: [
        {
          inputFilename: 'public/square.svg',
          outputFileName: 'icon-square',
          convertTo: 'png',
          sizes: [16, 32, 45, 900],
        },
        {
          inputFilename: 'public/circle.svg',
          outputFileName: 'transparent-circle',
          convertTo: 'png',
          background: {r: 255, g: 255, b: 255, alpha: 0},
          sizes: [100],
        }
      ]
    }
  });

All generated images will be placed into the public/assets path of your application.
