Not directly. The issue that makes this complex is that some lut files (such as csp) can contain both 1D and 3D luts together. So the distinction between what should be considered 1-D, vs 3-D isn't al

Folks, As you may have noticed, ASC-CDL was selected for Sci-Tech consideration this year under the category of "Digital workflow specifications for managing color". http://www.oscars.org/press/pressr

Hello ! I wrote a python script to plot 1D and 3D LUTs. It uses pyOpenColorIO to read and process LUTs and matplotlib to plot them. For the moment, I have to specify manually if the LUT is 1D or 3D to

Hi guys, I noticed there is an issue with getting the active Views list when it has been overridden in the environment using OCIO_ACTIVE_VIEWS. I've attached a patch that will fix this. Also I noticed

Hi, The convert utility seems to only convert a given image from one color space to another. How can I convert the LUT itself? Specifically, I am trying to convert Iridas .CUBE to Lustre .3dl Plz help

Are you running make with parallel jobs enabled (e.g. "make -j 4")? If so, the real error is likely buried further back in the build output.

Hi, I'm trying to convert the S-Log2/S-gamut 10-bit 422 XAVC footage coming out of my Sony F55 camera to a sequence of Linear ACES RGB OpenEXR files. I would like to validate the assumptions I make th

Not sure exactly what you are asking, but.. The P3 to XYZ transform is typically done as a colour matrix and gamma adjustment, which could also be baked into a 3D LUT There is a description of the spi

Hi All, I am looking to build the core lib with the -D OCIO_NAMESPACE=foo option. Whilst this builds just fine, I see that the SONAME is unchanged with the above. So, how do you resolve ambiguities he

If your image is packed separately per channel (ex: RRRRRRR... GGGGG... BBBB.... ), the Planar ImageDesc is probably what you're looking for. Give that a try? PlanarImageDesc(float * rData, float * gD

Hi, In my application, images are split into their separate channels, and operations are performed per channel. I have individual float arrays for each channel (obtained via openimageio), and I would

It looks like Nuke 7.0v6 ships with the OCIOLookTransform node, though it's not exposed in the menus by default. Quoting the release notes... BUG ID 24785 - OCIOLookTransform was missing from the Othe

It seems like the OCIOLookTransform node mentioned on this page: http://opencolorio.org/userguide/looks.html Is missing from the OCIO bundled with Nuke 7.0v4. Has the LookTransform node been deprecate

Hi! So you shouldnt have to muck around with any of the specific underlying Transforms (you mention the log transform, and the file transform). The typical use case with OCIO is that these are all abs

After much struggle, I finally managed to get OCIO built on Windows, but there are several apparent bugs in the build process that require manual intervetion to work around. I ran CMake from the Visua

Hi! I'm attempting to get a linear workflow working in Silhouette (4.5.3), which uses OpenColorIO. I'd like to load in scene-linear EXRs, apply a 1D linear-to-CineonLog transform, and then apply a 3D
