Nodebox 2 works fine on the same computer. There is any way to open Nodebox 1 files .py on nodebox 2 ? Thanks for all!

This code will get the color information for a pixel at 200x200 in an image called bud.jpg. The printed result looks like this: Color(0.129, 0.145, 0.186, 1.000) Hope this helps.....

I am sorry if is not a great question but I doesnt found how to. M. ilmeditafuga Tue, 16 Feb 2010 17:24:04 GMT http://nodebox.net/code/index.php/shared_2010-01-21-14-35-23 Thanks a lot for your help. Tried your suggestion + a lot of different combinations of setting colormodes & file-formats. Results are always off, sometimes less, sometimes more (5-10% / value). I give up. I'll look into if theres some "post-processing" I can do in other software to correct the colors. I think I'll mail the developers also - if they could get this + PMS-color support : ) into NB2 then it would be quite something for us working with print! Thanks. rasnab Thu, 28 Jan 2010 22:34:30 GMT http://nodebox.net/code/index.php/shared_2010-01-21-14-35-23 Oh, sorry, I forgot that you had already tried .tiff and it didn't come out right. Josh Caswell Thu, 28 Jan 2010 17:47:29 GMT http://nodebox.net/code/index.php/shared_2010-01-21-14-35-23 Okay, a few more things to try, if you're inclined, though I'm not hopeful. I noticed while fooling around with HSB colors, the output was more accurate if I didn't call outputmode(HSB). It doesn't make sense, but it may be worth a stab for you to not call outputmode(CMYK). Also, although the file format may not be any use, .tiff seemed to have more accurate HSB and CMYK values. One other thing is that you can try is bypassing NB's color (although NB just uses NSColor anyways), like this: [source code] Overall, I'm pretty well stumped by this. It's possible that one of the developers can help if you email them, although I know they're pretty busy with NB2. Good luck!
