Installation
git clone https://github.com/BITPlan/com.bitplan.dragtop
mvn clean install -D createAssembly=true
or use the rebuild script which skips Tests and gpg signature
dragtop script
This is a convenience script to start your dragtop. You might want to adapt the base directory setting to your environment
#!/bin/bash
# WF 2019-02-17
#
# start dragtop
#
# uncomment to debug
# set -x
base=$HOME/source/java
case $(uname -a) in

esac
pdir=$base/com.bitplan.dragtop
if [ ! -d $pdir ]
then
echo "dragtop project missing - will get it"
cd $base
git clone https://github.com/BITPlan/com.bitplan.dragtop

cd $pdir
git pull
jar=$pdir/release/com.bitplan.dragtop.jar
if [ ! -f $jar ]
then

mvn install

java -jar $jar $*
Using the dragtop
Powerpoint extraction example
You you need one ore more Powerpoint files in pptx format e.g. http://people.apache.org/~sctemme/ApconEU2008/Performance_Out.pptx
Then drag & drop your powerpoint files.
Then drag & drop a "tool" which can be a jar that follows the dragtop plugin guidelines or simply a fitting rythm template. Dowload https://raw.githubusercontent.com/BITPlan/com.bitplan.dragtop/master/src/test/rythm/pptExtractor.rythm and drag&drop it.
As a result your browser should open and show you an "exported" version of your Powerpoint presentation with all images and text "extracted". You'll find the images in your /tmp directory.
