Hey Boudewijn, Sounds like the exposure function affecting the alpha channel. Alpha is usually normalized to 0 - 1, so it would make sense if positive exposure adjustments are clamped. Cheers,

Same here. But in that case, rather than fiddling with the locale (I wasn't sure of any unintended consequences of doing that), I swapped in a custom sscanf() that assumed decimal separators. Still,

Ben's description aligns with my own experiences. We had a similar bug reading/writing a text file with decimals, and fixed it in a similar way (by saving/setting/restoring the locale setting). ///d@

I've not had much experience with locales either, but it seemed like an interesting thing to read up on.. so.. With LANG=de_DE, sscanf expects to see floats like "0,12" (compared to 0.12 as required

Hi, I've got some problems using the code from the ocio display application in Krita, and I'm not sure what's going on. The problem is that when the exposure gets negative, the image gets more

Hm... I have to admit I dont have much experience with locales. Can someone with experience on such issues please comment? On first glance, it feels like it should certainly be fixed inside OCIO,

I think I found a bug in either my code or OCIO. When our software is run on a Ubuntu 12.04 machine with a German locale, parsing of srgb.spi1d fails and we get an "Invalid 'From' Tag" exception. I

My apologies that compilation is not easier on windows. Our choice to use an external shared_ptr, in retrospect, makes portability more challenging than it need be; this is one of our top priorities

After feedback from the community, I think its probably simplest to NOT have an OpenColorIO BOF this year. Given that we wont have the opportunity to prepare a rockin' BOF presentation, and that

For those of you attending SIGGRAPH 2012 in Los Angeles in August, we are throwing a get-together for developers and users of VFX-specific open source projects. This was a big hit last year, and a

I would definitely go if there was one, and probably drag a couple colleagues with me. I don't have that much to present, as we're only just on the verge of rolling it into the new cycle of projects,

Team OpenColorIO, Is there interest in having an OCIO Birds of a Feather this year? Would you attend? I am not inclined to prepare a presentation (like the last two years), but if there is interest

Re-sending this review request (code by Brian Hall) https://github.com/imageworks/OpenColorIO/pull/278 - Enables GPU accelerated OCIO on iOS devices, including ipad. One interesting implementation

Thanks for the explanation Ben. I've made it so a component called "ocio_context" appearing in the node will cause a context to be used and initialized with string props that appear in there.

As far as I'm aware, the only interesting difference between the CPU and GPU paths is the GPU doesn't currently do tetrahedral 3D LUT interpolation (it'll fall back to

Excellent! I have OCIO in our build system and integrated into our (new) renderer so things are going well. I have some questions (below) Yes it makes sense. The one thing I'm missing here is how you

Super excited about getting RV support. Can't wait! Allow me to take a stab at some of your questions. This will probably be a lengthy reply... Per-shot CDLs / OCIO::Contexts are two sides of the
