Re: nuke-default config only reports 1 view with OCIO2
Aha! Thanks for explaining that Patrick. I wasn't aware that OCIO 1 was doing it "wrong".

Re: nuke-default config only reports 1 view with OCIO2
Hi Paul,
Following the work on OCIOv2 we discovered & fixed an issue around the list of active displays & views in the OCIOv1 implementation. Let me first explain a little bit some lines from the nuke config impacting the displays & views: displays:
default:
- !<View> {name: None, colorspace: raw}
- !<View> {name: sRGB, colorspace: sRGB}
- !<View> {name: rec709, colorspace: rec709}
active_displays: [default]
active_views: [sRGB]
The first five lines define the list of displays and views, In the example, there is only one display named 'default' which owns three views named 'None', 'sRGB', and 'rec709'.The last two lines define the active displays and views. Here, only the 'default' display and the 'sRGB' view are active i.e. the others are hidden. The OCIOv1 implementation was only implementing the filtering and ordering of the active displays i.e. the active view line was ignored. So, the master branch (i.e. OCIOV2) does now correctly handle the two active lists explaining why only the 'sRGB' view is accessible. In order to see all the views, the last line must be removed or changed to 'active_views: []'. Note: As mentioned by Doug, a pull request around displays/views is coming. Part of the changes is to add some methods in the public API to access all the displays & views. Note: With or without the active lists in the config, the envvars OCIO_ACTIVE_DISPLAYS & OCIO_ACTIVE_VIEWS filter and order the displays & views (bypassing the active lists from the config).

Thanks for the report Paul. We will investigate the issue.
It's good timing because we are actually preparing a PR involving display/view stuff at the moment anyway. Doug |

nuke-default config only reports 1 view with OCIO2
I just noticed that nuke-default only reports one of its three views (sRGB) when queried with the OCIO2 API.
Is this a known issue or is it possible I'm somehow using the API wrong? Worked fine with OCIO 1.1. |

When Jeremy gave the summary talk at the Pickford Center when OCIO was under consideration for an Academy Sci-Tech award. Richard Edlund did the introductions of all the speakers, and he pronounced it "Open Colorio", coloor-ee-oh, rhymes with the name Victorio.
To this day, that's how it sounds in my head every time I see it written down. Happy anniversary!

Cheers Jeremy!
The name was an inspired choice. Many great projects rebrand at some point. I remember several of us had to get our Image Interchange Framework tattoos removed when the name was changed to ACES. ;)
Doug
p.s. And many thanks to Imageworks (shout out to Larry, Michael, and Sean!) for safely transitioning the project to its new home at the ASWF.

Re: Happy 10th
Jeremy Selan
Wow, 10 years!?!? I can't believe it. A huge thanks to everyone who has helped with its creation and adoptiontion. And a double thanks to those working today to keep it going strong. A little known bit of OCIO history... I had originally named it "OpenColorSpace", but Malcolm Humphreys kindly pointed out it was a terrible name. Here's the original thread: > I really find the name misleading, which was reinforced more when I was telling one of the digital sups about it at DrD today. His first response was asking which monitor probes it will support, which I then had to go through and explain what OCS is trying to achieve and what that would mean for productions at DrD (ie for DrD this doesn't replace truelight or cinespace, just compliments them). > > As I'm sure the main aim for this project is getting a wide adoption, I can see already the name could work against this. > > I would tend to lean away from using the word 'colorspace' as this is already a well established concept even if it is poorly understood / followed. > > Other names that I had floating around in my head: > - OpenColorWorkSpace > - OpenColorIO > - OpenColorFlow > - OpenColorWorkFlow > - OpenColorTransfer > - OpenColorBase Nice suggestions, Malcolm! :) |

Was just reading the CHANGELOG.md and noticed that the first named release, 0.5.4, was dated June 1, 2010. I believe the discussion started on the original google-group a few months earlier but nevertheless it feels like this past week was a sort of milestone.
Happy 10th, OCIO!
And many happy returns! (Of 0, of course.) ;)

Re: PyOpenColorIO - Converting a simple singe RBG array to another colorspace
mhamid3d@...
I accidentally replied to sender only, but Lary's solution worked! I was in the 255 range instead of float values. Thank you!

Re: PyOpenColorIO - Converting a simple singe RBG array to another colorspace
Larry Gritz
Which versions of OIIO and OCIO are you using? I'm not sure that official releases of OCIO (prior to the current master) will work with 8 bit integer pixels, which is what you'd get from a jpeg by default. So it may be misinterpreting the values. If you read with pixels = img.read_image(format='float') then you'll get float pixels, and perhaps that will match what Nuke is doing? As somewhat of an aside, maybe this is a contrived example and you need to do a lot more with PyOpenColorIO, but if all you are doing is color converting pixels you read with OIIO, an easier idiom would be:
and then you don't need to directly import or use OpenColorIO at all. (Though this assumes you built your OIIO with OCIO enabled.)
