Third-party software integration: SWFTools

To enable preview UI tab, OpenKM need to convert pdf files to swf.

Linux

Swftools can be installed running in terminal:

$ sudo aptitude install swftools

Enable in OpenKM.cfg:

system.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.

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
make
make install 

Improving performance

For better performance, use this configuration. Create file pdf2swf_wrapper.sh

#!/bin/bash

/usr/bin/pdf2swf $* -f -t -G -s storeallcharacters

The last 5 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

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, create file pdf2swf_wrapper.bat

c:\path\to\pdf2swf %1 %2 %3 -f -t -G -s storeallcharacters

The last 5 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

And don't forget to change the OpenKM.cfg file:

system.pdf2swf=c:/path/to/pdf2swf_wrapper.bat

Take a look at pdf2swf wiki for complete parameters reference, and remember that JBoss must be restarted after any OpenKM.cfg modification.
