[Swftools-common] Internal error: badly balanced softmasks/transparency groups

[Jakob Hohlfeld]

Hi to all,

I am using swftools-0.9.2 on an Ubuntu 12-04 machine. I want to convert a PDF 
to SWF. The PDF document is rich in graphics, transparancies and general 
design. I  don't know much about how the PDF was created, but running pdf2swf 
gives me this error:

> $ pdf2swf InputFile.pdf -o OutputFile.swf
> FATAL: Internal error: badly balanced softmasks/transparency groups

I searched the web and found a workaround: render graphics as bitmaps

$ pdf2swf -s poly2bitmap InputFile.pdf -o OutputFile.swf

Though this runs smoothly, the result is an SWF document that is missing some 
graphics at all. Distinguishing from the contents of the original document, 
there might be an alpha mask involved in the breaking of the transformation, as 
it was tried in the first place.

Could anyone give a hint about what to do about the softmasks/transparency 
error - at least beyond completely opting-out of vector graphics?

Thanks for your advice
Jakob
