[Swftools-common] SwfExtract does not detect transparent images in linked swf

[Basel Al-Mustafa]

Hello,

Why doesn't swfextract detect png files in the swf
file linked below? I use swftools-dev_2007-01-13 under
Linux. Here is the output without the ids:
Objects in file top.swf:
 [-i] 24 Shapes
 [-i] 30 MovieClips
 [-j] 15 JPEGs
 [-F] 2 Fonts
 [-f] 1 Frame

I tried extracting one shape and one movieclip but
still only jpeg files are detected, no pngs.
