[Swftools-common] unexpected green background in image during pdf2swf conversion

[Jonathan Lee]

Hello all:
I have a pdf file I created, the file is here:
http://www.badongo.com/file/11702728

I use pdf2swf to convert it to swf file, but I get a green background for the 
image on the pdf file
The result swf file is here:

Any ideas?

Thanks.
