[Swftools-common] Rendering glitches with flatten and ignoredraworder

[Tim Whittington]

I've observed a couple of glitches when rendering a PDF with the -i (ignoredraworder) option, one of which occurs when it is combined with -G (flatten).

I'm fairly Flash ignorant, but it appears that on some pages the shape that would fill the background (or parts of it) with white is not being drawn, and there are areas of transparency.
This isn't obvious in a web browser with a white background, but if rendered with swfrender and previewed (which shows these areas as grey) or displayed in a page with a colored background it becomes obvious.

In general the command I'm running is as below, but with the various combinations of -i and -G added to it:
pdf2swf -p 1-5 -v -f -T 9 -t -s storeallcharacters

When using this command, or combined with -G, I don't see any issues in the rendered.

When using only -i, the HP logo on page 3 is drawn with a transparent/grey box visible around it and to the right.
When -i and -G are combined, the same issue is present on page 3, but additionally the background of page 1 is transparent/grey.

I've uploaded the PDF and the various .swf renderings to http://ultradodge.minus.com/m11mXEkPw/4l if anyone wants to investigate (the background on that site shows up the areas I mentioned).
(Alternatively if someone can point me in the direction of what could be causing this I may be able to chase it myself).

cheers
