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.

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 --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 

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 every OpenKM.cfg modification.
