Glad you got it working!

Jeff

I apologize for the above mentioned statement. Alfresco share do generate thumbnails for PDF files, there might be some issue with my local installation.

Also, in the example I was trying I noticed that whenever I tried to upload a PDF file the content type of the file was application/binary in place of application/pdf. So I have changed the helloworldform.post.js script to get an existing file from Alfresco’s space. I have called createThumbnail method on this file and saved the file. I have used scImageThumbnail bean as an argument to the createThumbnail method rather than scPdfThumbnail. This has worked and I am able to generate the thumbnail of a PDF file as well as a MS-Word and MS power point files.

I have also thought in the same direction and checked whether share is generating thumbnails for PDF files or not. So in my local installation of Alfresco share when I upload a PDF file, it is not showing the thumbnail of the PDF and neither for the microsoft word documents. However thumbnails are generated for images as expected and text files in addition. I am debugging more into Alfresco Share to get some pointer.

So my next thought is maybe the thumbnail classes assume “graphic in, graphic out” and aren’t passing ImageMagick the options necessary to handle PDF. You’ll need to step through that code with a debugger to find out.

Another idea is to look at Share. I know it uses pdf2swf to convert PDF into a pageable SWF file which opens up when you “preview” a document. But it also generates a thumbnail. I grep’d the OOTB context files for a pdf thumbnail config and didn’t find one. So digging into Share to see if it is creating thumbnails of PDFs the same way you want to do it is another route to take.

Though I can generate thumbnails for image files, I am unable to do the same for PDF and other content types. I have ImageMagick and OpenOffice installed.

In order to configure PDF, I have added one more bean declaration in someco-thumbnail-context.xml file where I am specifying the contentType as application/pdf for scPdfThumbnail.

I have modified the javascript to generate scPdfThumbnail like:

for each (field in formdata.fields) {
if (field.name == “file” && field.isFile) {
filename = field.filename;
content = field.content;
mimetype = field.mimetype;
}
}

var newDoc = companyhome.createFile(filename);
newDoc.properties.content.write(content);
newDoc.properties.content.mimetype = mimetype;
newDoc.save();

newDoc.createThumbnail(“scPdfThumbnail”, true);

When I run this webscript and upload a pdf file, the script runs successfully and the file is uploaded. But no child thumbnail node is created corresponding to the pdf node.

I am unable to figure out the reason for this. Can you please help me out?

Also, what are the supported content types for which thumbnails can be generated?

You got it right. I have just changed the lucene query and got my thumbnails

I’d have to see your code to be much help but the error sounds as if you are calling a method on an object that is undefined or null. (Also, I don’t recognize the “createFile” method).

If you are trying to use “document.createThumbnail” then make sure your “document” variable is actually set to something. That variable gets set automatically if you execute server-side JavaScript against a piece of content through the web client UI via the “execute script” action. Otherwise, you’ll have to do a search or something else to populate it.

Hope that helps,

Jeff

Thanks for the example and the recorded demo of the same.

I am using Alfresco Labs 3c. I have deployed the thumbnail example to my Alfresco installation. But when I try to upload a file I get the exception:

org.mozilla.javascript.EcmaError – TypeError: Cannot call method “createFile” of undefined (AlfrescoScript#11)

The same exception I am getting with Alfresco Enterprise 3.0.1.

What could be the reason?
