Processing images

The Web Content Integrator has an image processing feature which allows images referenced within HTML and rich text elements to be created as image components while processing a feed.


Image processing configuration

The following parameters can be set in the WCM WCMConfigService service.

Enable and disable image processing

By default image processing is enabled. To disable image processing set the property: disable.img.processing=true

Enable and disable embedded rich text images

Images can be embedded directly into the rich text elements instead of first creating an image component. This functionality makes images within rich text elements consumed by the Web Content Integrator be processed identically to images added to rich text elements in the authoring UI. By default embedded rich text images are disabled. To enable them, set the properties:

  • disable.img.processing=false

  • richtext.embedded.images.enabled=true


Use absolute image source URLs

Images within HTML and rich text elements can be specified using absolute HTTP URLs within the image source attribute. The Web Content Integrator will process absolute image source URLs as specified in the feed.

Example feed item: 

<item>
    <title>RichText Component With Image 1</title>
    <pubDate>Thu, 30 Mar 2011 16:00:00 EDT</pubDate>
    <guid>Image_Example_1</guid>
    <ibmwcm:action>add</ibmwcm:action>
    <ibmwcm:itemType>Component</ibmwcm:itemType>
    <ibmwcm:element>
      <ibmwcm:type>rich text</ibmwcm:type>
      <ibmwcm:value>
         <![CDATA[
         <p>Image 1:</p><img src="http://wci-feed-server/img/f/flower.jpg"/>
         <p>Image 2:</p><img src="http://wci-feed-server/img/g/guitar.jpg"/>
         ]]>
      </ibmwcm:value>
    </ibmwcm:element>
  </item>


Use relative image source URLs

Images within HTML and rich text elements can be specified using relative HTTP URLs within the image source attribute and a base URL from the link element of the item. The Web Content Integrator will process relative image source URLs as a concatenation of the item's link element and image source attributes in the HTML.

Example feed item: 

<item>
    <title>RichText Component With Image 2</title>
    <pubDate>Thu, 30 Mar 2011 16:00:00 EDT</pubDate>
    <guid>Image_Example_2</guid>
    <link>http://wci-feed-server</link>
    <ibmwcm:action>add</ibmwcm:action>
    <ibmwcm:itemType>Component</ibmwcm:itemType>
    <ibmwcm:element>
      <ibmwcm:type>rich text</ibmwcm:type>
      <ibmwcm:value>
         <![CDATA[
         <p>Image 1:</p><img src="/img/p/penguin.jpg"/>
         <p>Image 2:</p><img src="/img/s/sunset.jpg"/>
         ]]>
      </ibmwcm:value>
    </ibmwcm:element>
  </item>


Use both absolute and relative image source URLs

Images within HTML and rich text elements can be specified using a combination of relative and absolute HTTP URLs within the image source attributes. The Web Content Integrator will process relative image source URLs as a concatenation of the item's link element and image source attributes in the HTML. The Web Content Integrator will process absolute image source URLs as specified in the feed.

Example feed item: 

<item>
    <title>RichText Component With Image 3</title>
    <pubDate>Thu, 30 Mar 2011 16:00:00 EDT</pubDate>
    <guid>Image_Example_3</guid>
    <link>http://wci-feed-server</link>
    <ibmwcm:action>add</ibmwcm:action>
    <ibmwcm:itemType>Component</ibmwcm:itemType>
    <ibmwcm:element>
      <ibmwcm:type>rich text</ibmwcm:type>
      <ibmwcm:value>
         <![CDATA[
         <p>Image 1:</p><img src="http://www.ibm.com/favicon.ico"/>
         <p>Image 2:</p><img src="/img/f/fish.jpg"/>
         <p>Image 3:</p><img src="/img/g/grapes.jpg"/>
         ]]>
      </ibmwcm:value>
    </ibmwcm:element>
  </item>


Expected results – rich text component

Example rich text component feed item: 

<item>
    <title>RichText Component With Image 4</title>
    <pubDate>Thu, 30 Mar 2011 16:00:00 EDT</pubDate>
