[Swftools-common] pdf2swf: This file is too complex to render - SWF only supports 65536 shapes at once error

[李欣]

Hello,

I am very new to Swftools,
and I have a question about pdf2swf.

I see the following errors when converting a PDF file to SWF.

   /pdf2swf -T 9 -f -t -G -s storeallcharacters input.pdf -o output.swf//
   //
   //ERROR ID Table overflow//
   //ERROR This file is too complex to render - SWF only supports 65536
   shapes at once.

   /

I googled this error, found that it could be fixed by adding "-s 
poly2bitmap".

Here are my questions:

1. Can I know if a PDF is too complex or not before actually converting it?

2. Is it possible to apply "-s poly2bitmap" option only when it is 
necessary?
 Because I heard people saying "-s poly2bitmap" would slow the 
converting process.

My Swftools version: 0.9.2

Thanks for your help in advance.
