Transform a image with Javascript

larade

Hello,  I have a problem to transform an image. I use a javascript script found in the Alfresco documentation. My version is 5.2.  The script :

// convert an image to JPG format and resize to thumbnail image
var thumbImage = document.transformImage('image/jpeg', '-resize 120');The log:
ERROR [org.alfresco.repo.jscript.ScriptNode] [defaultAsyncAction4] 08110207 Unsupported transformation: transformer.ImageMagick image/jpeg to image/png

Screenshot :


The image is well converted but the resize does not work. The mimetype (property of the image) can not change.
Being a beginner, I can not understand the log message.
Thank you in advance for your help.

I had a problem with a "duplicate child name" when trying this.

var thumbImage = document.transformImage('image/jpeg', '-resize 120',document.parent.parent);

worked for me and the thumbnail is created on folder above the document (just for testing). But I didn't get the conversion error...

...ok, I first tried your original js-line with a png and everything works. The 120px Thumbnail is created. So it seems to be a problem with the setup.

I used Alfresco Community 5.2 on Ubuntu Linux and the image.magick version provided by alfresco installer for the test.

Thank you Martin for your reply 🙂

Actually, I had modified the script mimetype line ('image/png'). I had the same error as you concerning the duplicate child name.

I have the same version as you (5.2 Community and the default version of ImageMagick). Did you modify settings particularly?

For additional info, I run the script with a rule on a folder? (as admin)

Did you test the script that way too?

Thanks in any case for your help 🙂

I didn't modify any settings - but I installed the "missing libraries" (Installing Linux libraries manually | Alfresco Documentation ) before the Installation of Alfresco.

When dealing with conversion problems, I add

log4j.logger.org.alfresco.repo.content.transform.TransformerDebug=debug
log4j.logger.org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker=debug
log4j.logger.org.alfresco.util.exec.RuntimeExecBootstrapBean=debug
log4j.logger.org.alfresco.util.exec.RuntimeExec=debug

to the custom-log4j.properties in tomcat/shared/classes/alfresco/extension

Using the mime types url (.../alfresco/service/mimetypes) you can see which conversions are possible for the configured mime type. The listing for image/jpeg is very long on my system.

Thank you Martin for your responsiveness. I will look at the side of the libraries because I modified the file "custom-log4j.properties" like you without success. I'll let you know. It's amazing anyway.

Martin,

Can you tell me if you have the same thing when you open in the list "Registered Mimetypes" jpg or png: I have this: Transformable To: Can not be transformed into anything else
