The pdf2swf seems to be a great tool, but I am running into some 
challenges that I need help finding answers.  I am using the tool on a 
coldfusion server (windows, 32 bit) to convert pdf's that are submitted 
over the web.  The swf files are then displayed to users within a Flex 
application.  For the majority of the files it works perfect.  However, I 
am running into the following problems:

I am running all of the conversions with a -G (flatten) param.

1.  Some pdf's do not convert.  If I run them manually I get the error 
message "This file is too complex to render - SWF only supports 65536 
shapes at once".  The message is obvious - what suggestions can I give to 
users so this does not happen?

2.  Some of the converted files do not load into the flex application. 
When I try to open them independently in a browser like chrome the plugin 
will consume over 50% cpu utilization and I get a message that the plugin 
is not responsive.  Any ideas on what can cause this or how to 
troubleshoot.

3.  Some pdf's will convert to swf files that are MUCH larger than the 
original file.  The majority of the time the swf is smaller.  What will 
cause the swf file to convert so large.

I am not that knowledgeable with the details of swf or pdf files.  Ideally 
I would love to correct all of these problems, but I would be satisfied 
with instructing users how to create pdf's that do not fall into these 
problems.

Thanks in advance.
