[Swftools-common] PNG transparency with 32bit PNG

[Gernot Frisch]

Hi,

this PNG has alpha-bits:
http://www.glbasic.com/beta/swftools.png

But it shows a white frame instead of transparent pixels. I use the latest 
snapshot, where some PNG transparency issue was fixed:
2007-01-10-2008

Boy, if you can get this working, these tools are the greatest swf creation 
tools around!

Regards,
