[Swftools-common] Parse hotspots in PDF to create popups in SWF

[jan bahnsen]

Hello,

Iam creating a catalog application, where i need to have popups that
appear when you mouseover a certain product. these popups should be
fed from an external XML file, depending on the popup.

Because this application shall run on the end-users side, the actual
defintion of the mouseover areas should be handdled thru the source
PDF instead of creating another authoring applicatoin for this.

My idea is:

1) - user creates an area (e.g. a web-link hotspot) in PDF and tags
this area with an ID instead of a web address
2) - PDFs are converted using pdf2swf
3)  - a script parses the swf to know the coordinates of the active
area and also gathers the ID for this area
4) - swfc is used to create the logic for the converted SWF to know
which ID needs to be filled with which content


where i am struggling now is 1) and 3) because i havent figured out
yet how to find out the exact coordiates of e.g the created hotspot.

does anybody have any suggestions on this?

thanks & regards,

Jan.
