It would be exciting if you could convert a PowerPoint presentation to flash in a completely free way. With a lot of net searching and tutorial reading, I was able to do it with some Open Source Tools. You can read this step-by-step tutorial to learn the details.


Step 1

I launch Open Office in headless mode with a Mac. Then I open an Xterm and do the following

$ cd /Applications/OpenOffice.org 2.0.app/Contents/MacOS/program/ $ ./soffice -headless -accept="socket,port=8100;urp;"


Step 2

Download JOOConverter from
http://jooreports.sourceforge.net/?q=jooconverter
JOOConverter is an Open Source Java/OpenOffice Document converter to perform conversions between different office document formats.

I use a Java Library JOOConverter to convert my PowerPoint to flash by running

$ java -jar jooconverter.jar powerpoint.ppt flash.swf


The converted flash does not look pretty good with some strange artifacts in it. But it does play with a flash player although no other SWF tool is able to handle or even to read this flash file by Open Office. So I decided to find a tool to tidy up the flash file.


Step 3

Download Transform SWF from
http://sourceforge.net/projects/transform-swf
The Transform SWF framework is the tool to parse and encode Flash (.swf) files.

I finally managed to find Transform SWF to rewrite the flash file. I Load it into Transform’s internal swf model and then write it out again. With some nasty hacking of the Transform source, I was able to swallow exceptions caused by the out-of-bounds pointers in the swf file generated by swallow exceptions. And once again, it worked.

I think it would be troublesome to convert a PowerPoint to flash in this way if you do not have some programming experience. For the practical things, you may try some commercial converters in the market like Wondershare PPT2Flash Standard at

Featured Flash FLA

» Description:

The flash's horizontal road drive was done in CS4 and was upgraded to CS6. The car responds to right/ left key and flash will auto-generate the movement of roads from left-right or right-left based on random number. Have fun driving in this virtual environment and avoid other cars... :) If you are creative, a road driving game can be created from it.
