Issue on document preview in liferay 6.1EE

[jinish shah，修改在12 年前。]

Hi all,
we are using liferay 6.1 EE and in that Document and Media portlet providing document preview for only PDF files.
For doc,ppt file preview we need to install a ImageMagick and ghostscript.We have installed it and set below properties in portal-ext.properties
openoffice.server.enabled=true
imagemagick.enabled=true

And for linux system we used below proerties.We may also need to configure the path for fonts used by Ghostscript for linux environments imagemagick.global.search.path[Unix]= /usr/local/bin:/usr/share/ghostscript/8.71/Resource/Font

And for windows system we used below properties
imagemagick.global.search.path[windows]=C:\\Program Files\\ImageMagick

Preview is working perfactly in windows machine.But in linux machine preview is not generating.

We took a reference from this link
http://www.liferay.com/community/wiki/-/wiki/Main/Preview+Generation
http://www.liferay.com/community/wiki/-/wiki/Main/Document+Conversion+with+OpenOffice
Has anyone faced such issue before?
Please share any ideas regarding this.

Any error in logs?
If you enable openoffice you'd have to startup the openoffice server and configure the port in Liferay side.

No there is no any error log in back-end.
We have started openofffice server by this command

soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

And put the following properties in portal-ext.properties
openoffice.server.enabled=true

imagemagick.enabled=true

imagemagick.global.search.path[Unix]= /usr/local/bin

Also when i enable a log of
com.liferay.portlet.documentlibrary.util
I got this info message
INFO [PDFProcessorImpl:493] Excecuting command 'convert -alpha off -density 300x300 -adaptive-resize 1000 -depth 8 /opt//liferay-portal-6.1.10-ee-ga1/tomcat-7.0.25/temp/liferay/document_conversion/180103.1.0.pdf[0] /opt/liferay-portal-6.1.10-ee-ga1/tomcat-7.0.25/temp/liferay/document_thumbnail/180103.1.0.png '

The issue is resolved now.We put wrong path of convert command.You can get the path by "Which convert" command.It is either "/usr/bin" or "/usr/local/bin".
And also check that libpng-devel is install or not.

Thanks, got ImageMagick to work finally!

The default Liferay value (Path) for ImageMagick in the control panel is

/usr/local/bin:/usr/local/share/ghostscript/fonts:/usr/local/share/fonts/urw-fonts

What about urw-fonts, should they be installed and if so, how to install them in Ubuntu?
