Third-party software integration: SWFTools
To enable preview UI tab, OpenKM need to convert pdf files to swf.
 |
Starting from OpenKM 5.1 this configuration property has changed to system.swftools.pdf2swf. |
 |
Since OpenKM 5.1.9 the pdf2swf command line parameters should be added in the configuration property, for example:
system.swftools.pdf2swf=/usr/bin/pdf2swf -T 9 -f ${fileIn} -o ${fileOut}
|
See FlexPaper: Converting Documents for more info.
Linux
Ubuntu
Swftools can be installed running in terminal:
$ sudo aptitude install swftools
Enable in OpenKM.cfg or Administration > Configuration depending on your OpenKM version:
system.swftools.pdf2swf=/usr/bin/pdf2swf
|
In Ubuntu 10.04 is possible you need to add this line to /etc/apt/sources.list
deb http://archive.canonical.com/ubuntu lucid partner |
|
In Ubuntu 10.10 this package is not included, so you need to compile it or grab from https://launchpad.net/~ella-animation/+archive/dev:
$ sudo add-apt-repository ppa:ella-animation/dev $ sudo aptitude update $ sudo aptitude install swftools |
Red hat
Better if you compile version 0.9.x
$ yum install zlib-devel libjpeg-devel giflib-devel freetype-devel gcc gcc-c++ $ wget http://www.swftools.org/swftools-0.9.1.tar.gz $ tar xzf swftools-0.9.1.tar.gz $ cd swftools-0.9.1 $ ./configure --prefix=/usr/local $ make $ make install
Debian
This package is not include in the Debian repositories, so you need to compile from source:
$ aptitude install build-essential libgif-dev xpdf libfreetype6 libfreetype6-dev libjpeg62 libjpeg8 libjpeg8-dev $ wget http://www.swftools.org/swftools-0.9.1.tar.gz $ tar xzf swftools-0.9.1.tar.gz $ cd swftools-0.9.1 $ ./configure --prefix=/usr/local $ make $ make install
Or you can try to install the Ubuntu package. For Debian Squeeze I recommend the Ubuntu Lucid package.
Improving performance
For better performance, use this configuration.
system.swftools.pdf2swf=/usr/bin/pdf2swf -T 9 -f -t -G -s storeallcharacters -f ${fileIn} -o ${fileOut}
The parameters specifies that:
- -f : Fonts should be embedded, improves searchability in the document
- -t : Inserts a stop between each frame, improves stability
- -G : Makes the document smaller and faster to render
- -s storeallcharacters : Stores all character information about the texts in the document, improves searchability
OpenKM 5.0.x
Create file pdf2swf_wrapper.sh
#!/bin/bash
/usr/bin/pdf2swf $* -f -t -G -s storeallcharacters
Make it executable:
$ chmod +x pdf2swf_wrapper.sh
And don't forget to change the OpenKM.cfg file:
system.pdf2swf=/path/to/pdf2swf_wrapper.sh
|
Take a look at pdf2swf wiki for complete parameters reference, and remember that JBoss must be restarted after every OpenKM.cfg modification. |

Windows
Donwload last swftools http://www.swftools.org/download.html and install it.
Enable in OpenKM.cfg ( put this character to indicate path separator "/" not "\" )
system.pdf2swf=c:/program files/swftools/pdf2swf.exe
Improving performance
For better performance in conversion,
system.swftools.pdf2swf=c:/path/to/pdf2swf.exe -T 9 -f -t -G -s storeallcharacters ${fileIn} -o ${fileOut}
The parameters specifies that:
- -f : Fonts should be embedded, improves searchability in the document
- -t : Inserts a stop between each frame, improves stability
- -G : Makes the document smaller and faster to render
- -s storeallcharacters : Stores all character information about the texts in the document, improves searchability
OpenKM 5.0.x
Create file pdf2swf_wrapper.bat
c:\path\to\pdf2swf %1 %2 %3 -f -t -G -s storeallcharacters
And don't forget to change the OpenKM.cfg file:
system.pdf2swf=c:/path/to/pdf2swf_wrapper.bat
