[Solved]Created Thumbnail is size 0 bytes, nothing to see!

sgomez — Tue, 08 Dec 2009 00:09:09 GMT

I can successfully create a thumbnail (I can confirm by seeing a new child node created after running webscript) but the file is size 0 for every thumbnail I create and so there is no actual thumbnail to preview. I tried creating thumbnails based on the OOTB thumbnail definitions as well as Mr. Po

I have the same problem with Community 3.2r2. Someone can help me?
Thanks

I still can't successfully generate a thumbnail in Share, but I am able to generate a thumbnail using ImageMagick from the command line with no problem.

I took the Command: from the log that was generated when debug is enable and it won't run without first removing the commas between each of the command parameters. I was thinking that the log included the commas for readability, but I found another post where they can successfully generate a thumbnail and their command statement does not include commas between the parameters. What would cause this difference in command?

Here is a sample from a successful execution that I found in another forum post - there are no commas between command parameters:

21:55:10,938 DEBUG [org.alfresco.util.exec.RuntimeExec] Execution result:
   os:         Linux
   command:    convert /opt/Alfresco/tomcat/temp/Alfresco/ImageMagickContentTransformer_source_3101662635154708545.jpg /opt/Alfresco/tomcat/temp/Alfresco/ImageMagickContentTransformer_target_4975277974653078577.jpg
   succeeded: true
   exit code: 0
   out:
   err:

Here is the log from a zero byte size execution - note the commas between parameters in the command:

command:    [C:/devtools/ImageMagick-6.5.7-Q16/imconvert, C:\devtools\apache-tomcat-6.0.18\temp\Alfresco\ImageMagickContentTransformer_source_6794085110837159309.png[0], -thumbnail, 100x100, C:\devtools\apache-tomcat-6.0.18\temp\Alfresco\ImageMagickContentTransformer_target_9019625159893596094.jpg]

I am receiving the same exit code as the poster above:

   succeeded: true
   exit code: -1072365564

Hi all,
referring to this post http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14528 I tried to add SystemRoot to imagemagick enviroment and it works!

So you have to add an entry in processProperties with key SYSTEMROOT and relative value (es. C:/WINDOWS) to imagemagick-transform-context.xml (or create a new one in alfresco/extension)


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>

   <bean id="transformer.worker.ImageMagick" class="org.alfresco.repo.content.transform.magick.ImageMagickContentTransformerWorker">
…
            <property name="processProperties"> 
               <map>
                  <entry key="MAGICK_HOME">
                     <value>${img.root}</value>
                  </entry>
                  <entry key="DYLD_LIBRARY_PATH">
                     <value>${img.dyn}</value>
                  </entry>
                  <entry key="LD_LIBRARY_PATH">
                     <value>${img.dyn}</value>
                  </entry>
                  <entry key="SYSTEMROOT">
                     <value>C:/WINDOWS</value>
                  </entry>
               </map>
            </property>
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Restart alfresco and now exitcode is 0 and size > 0.

Nicola –

I've confirmed that the fix is working for me as well. Thank you! Great find.

I'd award give points on this, but the option isn't appearing. Perhaps only the originator of the post can award points.

So I take it that this is a Windows problem only. Surprised more people haven't reported this issue. Will you be posting to Jira? I'd be happy to do that if you'd like.

I'm not registered to jira. You can post it. Thanks

Thank you so much for keeping this thread alive. I am very sorry for not keeping up with it. But I will give credit where its due and that is to Nicola. I've marked your solution as helpful. Although I haven't tried it myself, it looks like it has helped someone already. I will definitely give it a try as well hopefully after I'm done with my current task. Again, thanks!
