@namekuseijin, thanks and no reason to be sorry, we're all working on improving this great software. :)

@Lord Crc, Dade, yeah, path integrator made it! Switching from bidir to path resolved the alpha edges issue in PNG-RGBA output, they are nice and soft. TGA-RGBA is still broken. Tested in both 0.6-final and yesterday's tip (gcc 4.4). Lxs contents is below if you're still interested. :)

Hi,

Lord Crc just fixed a bug in bidir related to this issue.

Jeanphi

[SATtva]

Yes, already noticed. I'll check it in a couple of hours.

[SATtva]

Fix confirmed: alpha channel output is according to the defined settings, edges are smooth, tested with path and bidir. Much thanks Lord Crc! :)

[Lord Crc]

No problemo. Does TGA RGBA output work as well? It does here, so would be nice if it did for you too

edit: that is, I committed a fix to RGBA output for TGA as well yesterday

[SATtva]

Yep, I wasn't specific enough: RGBA output is fixed for both TGA and PNG formats. I used the latest tip.

If bugs in other software would have been fixed that promptly, what a wonderful world we could be live in.

[Lord Crc]

Well if only the bugs were that easy to fix, perhaps...

edit: cheers for testing btw
