Nuxt Image has first class integration with ImageEngine

Integration between ImageEngine and the image module.

At a minimum, you must configure the imageengine provider with the baseURL set to your ImageEngine Delivery Address:

export default {  image: {    imageengine: {      baseURL: ''    }  }}

ImageEngine fit values

The standard values for fit property map onto ImageEngine Directives as follows:

  • cover: m_cropbox
  • contain: m_letterbox
  • fill: m_stretch
  • inside: m_box, this is the default fit method for the ImageEngine provider.
  • outside: This fit method is not supported and functions the same as inside.

ImageEngine modifiers

In addition to the standard modifiers, you can also use all ImageEngine Directives by adding them to the modifiers property with the following attribute names:

  • format: f directive
  • fit: m directive
  • passThrough: pass directive
  • sharpen: s directive
  • rotate: r directive
  • screenPercent: pc directive
  • crop: cr directive
  • inline: in directive
  • metadata: meta directive

Note that the standard quality attribute is converted to the ImageEngine cmpr compression directive. quality is the opposite of compression, so 80% quality equals 20% compression. Since ImageEngine automatically adapts image quality the visitor's device, browser and network quality, it is recommended that you do not explicitly set the quality. If you want to completely disable all optimizations to an image, you should use :modifiers="{ passThrough: 'true' }", which will serve the unaltered image.

Example 1: Cropping an image to a width and height of 100x80, starting 10 pixels from the top and 20 pixels from the left:

<nuxt-img  provider="imageengine"  src="/some-image.jpg"  width="100"  height="80"  :modifiers="{ cr: '100,80,10,20' }"/>

Example 2: Instruct ImageEngine to keep the image's EXIF metadata (which is normally removed to reduce the image byte size):

<nuxt-img  provider="imageengine"  src="/some-image.jpg"  width="100"  height="80"  :modifiers="{ meta: 'true' }"/>

ImageEngine best practices

Automatic format and quality detection

ImageEngine automatically detects the best format and quality for your image based on the characteristics of the specific device that requested it.

This feature is very effective and it is not recommended that you disable it, but if you must, you can manually specify the format (ex: format='webp') and quality (quality='80').

ImageEngine settings

ImageEngine allows you to set all of the modifiers/directives in the ImageEngine control panel under advanced settings. This is a good place to set default adjustments since you can modify them without having to make changes to your Nuxt codebase. If a directive is set in both Nuxt and the ImageEngine User-Adjustable Settings, the value in Nuxt takes priority.
