I've exposed a gamma control for the Nuke OCIODisplay node. The gamma
control, like the origin one in nuke's monitor, is post-display
transform.

0.7.4 Released

Jeremy Selan <jeremy...@...>
 

Version 0.7.4 (Jan 4 2011):
* Added Context, allowing for 'per-shot' Transforms
* Misc API Cleanup: removed old functions + fixed const-ness
* Added config.sanityCheck() for validation
* Additional Makefile configuration options, SONAME, etc.

Coming soon...
* Docs / Examples
* "Looks"
* IIF Profile


Re: Review: Makefile updates

Jeremy Selan <jeremy...@...>
 

Yah, these conflict in:
export/OpenColorIO/OpenColorIO.h
src/pyglue/CMakeLists.txt

Looks easy to address though. Why don't you checkin the extra build
option to make the docs optional on your master, and then i'll fix it
to work on the new trunk? (or you can do the merge too if you'd like)
;)

Unfortunately on my machine I'm not able to make that directory have
write permissions. (and you shouldnt need root to do a 'make') What's
it trying to do? Can we have it do its work locally in the cmake build
dir? I also dont have pdflatex.fmt. in that directory.
It should be trying to do it all in the build/ directory, so this is a little strange.

Does this require users to have additional libraries on their system?
I have included all the additional libs for the html build, and install of Latex is the only external dep needed for the tex -> pdf build.

Should we make the docs building optional? (If your system doesnt have
the right libraries, it skips?)
It should skip the pdf build if Latex isn't found, but it seems it's found on your system and doesn't work.

Can you print out ${PDFLATEX_COMPILER} in the docs/CMakeLists.txt? Is this on OSX or Linux? It worked out of the box on debian 'testing' and centos.

On osx I have latex installed as part of the MacTex disto http://www.tug.org/mactex/ (1.6G eek?) To get cmake to pick it up I just set the PATH env to include '/usr/local/texlive/2010/bin/universal-darwin'

I was thinking of adding the 'doc' and 'pdf' targets just to the 'install' target so that they don't get triggered all the time when you call 'make'. You will still be able to call 'make doc | pdf' if your working on the doc strings.

I recon the 'pdf' target should be enabled by an option if it continues to be flaky.

I haven't added it yet but sphinx should be able to use autodoc to create the docs automagically for the python binding.

Thanks, I've addressed all comments and rolled it into master.

'context' varies it's position in few of the argument list.
Fixed.

What would cause the g_fileExistsCache to be flushed? I could see this could be problematic if a client app was running for a while and files started to change on disk.
Currently, nothing causes it to be flushed. Adding a library-wide
"flush cache" call is at the top of my todo list. (It was already
written up as github issue #46)

In the future is the idea to add a section into the yaml which LoadEnvironmentVariables() can use to limit which variables it looks up?
When I started adding the code, there didnt seem to be a clear
advantage to adding complexity by requiring all env-vars to be
pre-declared. Any advantages you can think of? Only one that comes
to my mind would be a place to add a default value, if the value is
not otherwise defined in the environment.
I guess I was mainly thinking about speed, I have seen people create a hell of a lot of environment variables. But your right we can add that complexity later when / if that becomes a problem.

'context' varies it's position in few of the argument list. It would be nice if this was more consistent. ie. BuildColorSpaceOps(ops, config, context, src, dst) vs getProcessor(src, dst, context)

It feels better to me to change getProcessor to (context, src, dst) but either way would work.

Can we rename GetPreppedSearchPath to something like ResolveSearchPaths?

Resolves Issue #16:
http://github.com/imageworks/OpenColorIO/issues#issue/16

This commit enables color transforms to leverage environment variables
+ search paths to determine the lut location. This will enable
workflows where the looks changes across different
shots/sequences/etc. For apps which work in the context of a single
shot, no changes are required. And, for apps which span multiple
shots (such as a playback utility), a mechanism is provided to update
the variables at runtime.

We introduce a new class, OCIO::Context, that is responsible for all
of the work involved in turning a short filename into full path. (it
handles both envvar interpolation and search paths). Profiles, on
construction, automatically get a default context which contains the
full environment. New versions of getProcessor have been added that
take a context as an argument, allowing the default context to be
overridden at runtime. If no context is provided, the default is
used.
