Make flash plugin from a png
This is a guide to creating a Family tree that can be viewed in a web-browser in a convenient way by allowing zooming in and out and navigating the image of the tree.
Installation of necessary tools
- Install swftools: 
- use the Graphviz plugin to generate a graphical report (see Howto:_Make_a_relationship_chart)
Generation of Flash file
Flash is a proprietary format, of which however open implementations exist. You have to install a flash player and a browser plugin, to be able to view a flash file in firefox, konqueror, ...
You can create the flash file as follows:
- If the report image is called "report.png", execute "png2swf -o report.swf report.png" on the command line.
- There should now be a file report.swf, that can be opened in any browser with a flash-plugin. You can zoom by right-clicking in the image and choosing zoom in from the menu, and you can navigate by "dragging the image" inside the window with your mouse.
I did this with the result of Example 2 on Howto:_Make_a_relationship_chart, and the resulting file may be available here soon. I named it ancestorsAndDescedants.swf.
- The .dot file generated in example 3 on Howto:_Make_a_relationship_chart seems to contain the web-page addresses to the personal pages of the "Narrative Webpage" report pages, and it would be nice to have links from inside the flash-application to the personal homepages. I do not know if this is possible.
