    media:image

    Table of Contents

    Description

    The Image tag displays images from a given field in a result or a src. It will automatically resize and cache the image for performance.

    The following module will need to be added to your pom.xml in order to use the twigkit image-service.

    <dependency>
     <groupId>twigkit</groupId>
     <artifactId>twigkit.media</artifactId>
     <version>${project.parent.version}</version>
</dependency>

    If your image is within an expression you will need to use the trusted filter eg (<media:image src="{{imageUrl | trusted}}"></media:image>)

    If you are combining plain text with a variable it is recommend that you do this within a function in a controller. You can see this in the example below. This will remove the chance of getting a 404 in the JavaScript console caused by a request for the image being sent before the values in the src attribute were evaluated.

    Example

    Controller

    $scope.myImageUrl = function(result){
   return 'http://placehold.it/' + result.fields.x.val + 'x' + result.fields.y.val;
}

    View

    <media:image src="{{myImageUrl(result) | trusted}}"></media:image

    Usage

    as element:

    <media:image
       [result="{object}"]
       [field-name="{string}"]
       [field-prefix="{string}"]
       [field-suffix="{string}"]
       [src="{string}"]
       [lazy-load="{boolean}"]
       [fallback-image-url="{string}"]
       [width="{number}"]
       [height="{number}"]
       [alt="{string}"]
       [url="{string}"]
       [cache-original="{boolean}"]
       [image-service-url="{string}"]
       [use-headers="{boolean}"]>
</media:image>

     Rather than specify a field-name, provide a URL to the desired image. If
