Re: [Swftools-common] Segmentation fault while converting pdf to swf

[Chris Pugh]

Finally got at your at your pdf file:

Filename:   EMPIRE_03_2010.pdf
Size:          39Mb
Creator:     Adobe InDesign CS4 (6.0.1)
Producer:   Adobe PDF Library 9.0

Conversion with pdf2swf binary from swftools 0.9.0, under generic
Linux 2.6.28 ( both source code installs ),
proceeds perfectly.  Several passes were made.   On each pass, all 116
pages of the 39MB file converted without
a single error being thrown.

Better check your environment, swftools install, etc, etc, etc.

Regards,


Chris.
