Cmis: How to create renditions

richardeb

Hello,

the alfresco cmis interface returns only existing renditions for a document.(e.g a preview) How can I force alfresco to create the renditions files (e.g. the preview) if they don't exist?

Thank you

I'm afraid you can not create renditions using CMIS directly.

Oh that are bad news. But maybe I found a solution. I created a folder for all documents that I want to retrieve with cmis. Then I added the following script as a rule (for adding/updating documents) to this folder

//EDIT: script-Update

try
{
   function main()
   {

      var thumbs=document.getThumbnailDefinitions();
      try
      {
         if(contains(thumbs,"doclib"))
            document.createThumbnail("doclib");
      }
      catch(err)  {  }
      try
      {
         if(contains(thumbs,"webpreview"))
            document.createThumbnail("webpreview",true);
      }
      catch(err)  {  }
   }
   function contains(a, obj) {
      if(a.length>0){
         for (var i = 0; i < a.length; i++) {
            if (a == obj) {
               return true;
            }
         }
      }
      return false;
   }
   main();
}catch(err)  {  }

Is this a common solution or do you have a better solution? What about the performance? Ist this code always working(subfolder/edit/update/updates by other scripts/…)?

Thank you

Unfortunatly the script doesn't work correct. If I upload a docx file the upload fails. Do you have any solution how to fix this? Thank you

Ye using rule on a folder that creates the rendition is a good solution
When creating the object using CMIS will trigger the rule which creates the rendition.

Unfortunatly document.createThumbnail("doclib") fails when executed on a docx file.

If the rule is defined as synchron document.createThumbnail("doclib") throws an error that causes a rollback. (I can't prevent/catch this). If I define the rule as async document.createThumbnail("doclib") will never work. (I tested this using the share frotend itself for adding documents)

please call javascript rendition service api like following

var renditionDef = renditionService.createRenditionDefinition('cm:pdfExport', 'reformat');
renditionDef.parameters['mime-type'] = "application/pdf";
var renditionNode = renditionService.render(document, renditionDef);

It works perfect. Thank you very much.
