UCM: Image Conversion Using DAM with ImageMagick

When a digital asset is checked in to Content Server, Digital Asset Manager creates multiple renditions of that asset. For images, the criteria for each rendition is defined in one of two files. The default renditions set is defined in the damconverter_basedefinitions.hda file and should not be modified.

Custom rendition sets can be added to a component resource file called extraRendition_definitions.hda. This file can be created with a standard text editor and must be located in a new directory named dam in the refinery IntradocDir/data/configuration/ directory. The full file path should be:

C:\Oracle\Middleware\user_projects\domains\base_domain\ucm\ibr\data\configuration\dam\extraRendition_definitions.hda

After a rendition set is added to the extraRendition_definitions.hda file, it must be made available as an option in the Image Rendition Set field on the Content Check In Form, using Configuration Manager.

To add the name of the rendition set as an option in Configuration Manager, perform these steps:
1. In the Configuration Manager applet, select the PackagedConversions information field and click Edit. The Edit Custom Info screen is displayed.
2. Add the name of the new result set as it is listed in the extraRendition_definitions.hda file's packedConversion result set. In this case, add "Training".

Now upload a new image in Content Server. In the “Image Rendition Set” option, select “Training”. Click on the Check In button. Once it is uploaded successfully, you will see the below screen

Click on the Rendition Information Tab.
