Thanks for your answer.

Indeed, the dump outpout is huge for bad pages, more than 4 Mo for the text file, where as it is less than 100 or 200 Ko for other swf.
So yes it is not really pretty but it is the only useable solution I have at this time.

Thanks Tony.

I tried to join a zip file with the 2 problematic PDFs, but I have a mail delivery system e-mail in return (the address of swftools-common failed)
Is there a limit size for the  attachment files ?

Hi Sylvain,
Your PDF probably has many layers/objects which all get replicated in the SWF on conversion. If you run swfdump you will see the difference between a good/bad swf.
Try dumping the output of swfdump to a text file, the size of the text file is a reasonable indicator to identify "bad" PDF pages. Not pretty but it helps.

Subject: [Swftools-common] Problem with some converted swf


I have a problem with few swf converted by pdf2swf.
I have converted a PDF with just one page, but the flash player really has difficulties to read the swf generated.
In fact, it use many CPU ressources and it take a long time to display the swf (about 1 minute).

Have you ever seen this point ?

If I convert the PDF with -O1 option, the swf is nice and there is no problem with it.
So, is there a solution to fix the problem and to generate good swf ?
Or else, I search for a way to identify the few wrong swf before I load them in my program
(because if I load a wrong swf, it will use too many ressources on the computer of the user of my application)
in order to re-convert the pdf with -O1

The decompressed size of "wrong" swf is heavier than good swf. It's maybe an indicator for identification.
But I don't know how to get the decompressed size of a swf file in actionscipt.

I have 2 examples of one-page PDF wich give me a "bad" swf. Maybe can I send them by email ?
(and the 2 swf generated)


(sorry for my poor english)
