00:31 < pixelgeek> Or about an hour in this case.

00:50 < pixelgeek> mornin' pabs
00:50 < pabs3> yo
00:51  * pabs3 slightly hung over
00:51 < pixelgeek> You had a happy new year, I take it :)
00:51 < pabs3> aye
00:52 < pixelgeek> I had a beer on Tuesday and it took two days to clear the hangover.  I just can't take it like I used to. 
00:53 < pabs3> well this was from Friday nite, but yeah, NYE was good too
00:54 < pixelgeek> Sorry, yes, I figured it was from last night.  
00:54 < pixelgeek> Didn't mean to impy you were a lightweight. 
00:54 < pixelgeek> :)
00:55 < pixelgeek> Was there any decision on the numbering scheme?  Bones, chromakey, svg import etc, 
00:55 < pixelgeek> Gotta be worth a 0.70.0?  
00:57 < pabs3> heh. thing is, I'm very much a lightweight :)

04:50 < AkhIL> pixelgeek, pabs3, can you help me in layer coding?
04:50 < pixelgeek> !
04:51 < AkhIL> ?
04:51 < pixelgeek> Unlikely - unless it's an obvious typo
04:51 < AkhIL> http://akhilman.googlepages.com/chromakey-hsyuv.cpp http://akhilman.googlepages.com/chromakey-hsyuv.h 
04:51 < AkhIL> please search FIXME in cpp file
04:52 < AkhIL> I would like to integrate blur in this filter
04:52 < AkhIL> but don't know how to do that
04:56 < AkhIL> http://akhilman.googlepages.com/chromakey-hsyuv.cpp.bad - it was my attempt to merge blur layer with chromakey
04:56 < AkhIL> absolutely broken attempt
04:57 < AkhIL> surfaces and pans - is kind of synfig magic which very hard to understand for me
04:58 < AkhIL> especialy without documentation
05:00 < pixelgeek> I'm afraid it doesn't mean much to me. 
05:00 < pixelgeek> (apart from the fact that we usually spell blurred with two 'r's ;)
05:01 < pixelgeek> I'm assuming the extra code in .bad is from the blur layer.
05:01 < pixelgeek> How does it fail?
05:01 < pixelgeek> Does it compile?
05:02 < AkhIL> wait a minute. I'll try again
05:05 < AkhIL> aha... seems I understood my fault
05:05 < AkhIL> lat's try
05:07 < AkhIL> ok. one step forward
05:13 < AkhIL> http://akhilman.googlepages.com/chromakey-hsyuv.cpp this one mostly works
05:13 < AkhIL> except one thing
05:14 < AkhIL> blured_alpha = blurred[x][y].get_a(); seems gets value from wrong loacation

05:56 < pixelgeek> Hopefully dooglus will take a look at it in a few hours time.  
05:57 < pixelgeek> Ugh - my main synfig dialog has disappeared.  And that's the one with the 'reset all dialogs' menu item.  
05:57 < pixelgeek> And then everything implodes
05:58 < pixelgeek> good job I saved.  
05:58 < pixelgeek> I think...

06:20 < AkhIL> seems I have a solve of my problem. I may apply chroma key to surfaces extended by blur
06:21 < pixelgeek> :)
06:22 < pixelgeek> That makes sense.
06:22 < AkhIL> it will make some unnecesary computation. but will work
06:23 < pixelgeek> Is there a quick way to pick a good value for the color you're keying against?  
06:23 < pixelgeek> I find my self with the eye dropper
06:23 < pixelgeek> picking random points on the greenscreen...
06:24 < AkhIL> i'm using same way
06:24 < pixelgeek> Unfortunately, the canvas isn't refreshed until the colour is committed.  
06:24 < AkhIL> yes.
06:25 < pixelgeek> OK - just wondered if I was missing something.  
06:25 < AkhIL> chromakey can be extended to diffkey
06:26 < pixelgeek> Didn't have much luck with using difference keys either - auto white balance on the cmaera mucked everything up.  :(
06:26 < AkhIL> in this case it will be like pasteconvas layer with nested frame with clean background
06:26 < pixelgeek> s/cmaera/camera
06:27 < AkhIL> my camera have manual white balance
06:28 < AkhIL> I even got a way to make day to night shots using only manual white balance and exposure control
06:29 < AkhIL> fill computer screen with orange color, pick white balance probe on this screen. then decrease exposure. Then you can shot day to night without any filters
06:29 < AkhIL> everything will be blue and dark 8)
06:33 < pixelgeek> Sweet.  The camera I'm using has a manual white balance setup, but it's a pain to use, and I keep forgetting everytime I shoot what turns out to be a special effects shot.  
06:34 < AkhIL> ha-ha. same problem. Every time should check stabilization, focus, exposure and white balance settings
06:35  * AkhIL got a lot of bad shots because of had manual settings
06:35 < pixelgeek> Anyway, my current project finished rendering.  I'm still not happy with the movement, but I'll try and fix it up over the weekend.  
06:35 < pixelgeek> but for now....  bedtime.  
06:37 < pixelgeek> 'night all
06:37 < factor> see ya pixelgeek

10:00 < AkhIL> http://img360.imageshack.us/my.php?image=screendr1.jpg now I can key by blured image and apply mask to original image
10:00 < AkhIL> very usefull for noisy shots 
10:03 < rore> cool :)
10:05 < rore> shouldn't the border of the orange clothes be more transparent in the "keyed" image?
10:05 < AkhIL> work in progress... 8)
10:08 < AkhIL> i intent to use 3 step chromakeying
10:08 < AkhIL> first one determinates large background area
10:09 < AkhIL> second one keyes semi-transparent borders using blured alpha from previous step
10:09 < AkhIL> and third one removes spill effect 
10:13 < rore> ok. This will be great :) 
10:14 < rore> And I like the idea of using several steps. Hmm... I wish I could do something like that for gimp
10:15 < rore> (they have a "color to alpha" operation, but for example, if you set white to alpha, then in general the whole image became semi-transparent, because of course there's some "kind of" white everywhere in the image, unless it's totally black)
10:19 < AkhIL> in my keyer you will can key by hue, saturation, luminance, U, V and alpha
10:24 < AkhIL> next step will be writing paste canvas analogue but with spill effect

14:49 < AkhIL> not nice
14:49 < AkhIL> bluring not what I need in this layer
14:51 < AkhIL> I need dilate/erode instead of blur

16:24 < AkhIL> http://img134.imageshack.us/my.php?image=screenmp4.jpg not perfect 8(
16:30 < rore> hm, yes, not much difference except on the hair and on the face "shadow" (don't know how to call it)
16:57 < AkhIL> http://img171.imageshack.us/my.php?image=screenjo0.jpg - i like nodes 8)
