libTiff not listed as recommended prerequesite

Not sure how this slipped through, but libTiff should listed as a recommended prerequesite and installed by the package managers (i.e. homebrew)

Nuke CTL Node

I'm not sur this is the right way to go, but I couldn't find the appropriate mailing list.

In issue #26, there is mention of a Nuke CTL node. Does it exist, somewhere? If so, how do I compile and install it?

Thanks!

Vincent Olivier

NukeCTL and CTL_MODULE_PATH

CTL_MODULE_PATH env var seems to have to be set before launching Nuke such as imported modules of a CTL script could be found by NukeCTL node.

This can be annoying if different versions of the same transformation co-exist in CTL_MODULE_PATH.
Precise use case : comparing different versions of ACES RRT that have to import corresponding utilities modules.

Shouldn't CTL_MODULE_PATH be set automatically or in a transparent way ?

For what it's worth, in TuttleOFX CTL node, imported modules are searched in the directory of the loaded CTL.

Nuke_CTL is disabled as plugin

Hello

I'm IlmBase, OpenEXR, ampasCTL, OpenEXR_CTL maintainer for FreeBSD

http://www.freshports.org/graphics/ilmbase/

http://www.freshports.org/graphics/OpenEXR/

http://www.freshports.org/graphics/ampasCTL/

http://www.freshports.org/graphics/openexr_ctl/

And make new Versions.

I see that graphics/ampasCTL-devel (1.5) replace ampasCTL (1.4.1) and OpenEXR_CTL (1.0.1).

Here is installed

Nuke_CTL is not builded with ampasCTL-devel-1.5 i think because installed IlmBase / OpenEXR libraries

Get this with installation graphics/ampasCTL-devel-1.5

CMake Warning at Nuke_CTL/CMakeLists.txt:46 (message):
  NUKE not found, check NUKE_INSTALL_PATH setting or NDKDIR env.  var,
  NukeCTL plugin disabled

With intstallation get this problem and more others

Installing ampasCTL-devel-1.5...pkg-static: ampasCTL-devel-1.5 conflicts with openexr_ctl-1.0.1_1 (installs files into the same place).  Problematic file: /usr/local/bin/exr_ctl_exr

Is better to use Nuke_CTL or IlmBase / OpenEXR libraries?

CTL-ctl_1.5_rc handful of minor changes needed to compile "make check"

a few files in unittest were failing on "memcpy" so I added #include and a few math ones failed on srand/RAND_MAX so added #include to those.

Seems like maybe that wasn't the best solve because now make check compiles but 2 of 4 test fail, one with a segfault. Would there be a better way or better location (e.g. some header file) to put these standard libraries?

Start 1: IlmCtl
1/4 Test #1: IlmCtl ..........................._Exception: SegFault 0.17 sec
Start 2: IlmCtlMath

3/4 Test #3: IlmImfCtl ........................ Passed 0.06 sec
Start 4: ctlrender

50% tests passed, 2 tests failed out of 4

2 - IlmCtlMath (OTHER_FAULT)

CTL Brew formula is outdated

Installed ctl brew formula (it installed the other required formulae).

dyld: Library not loaded: /usr/local/lib/libImath-2_1.11.dylib
  Referenced from: /usr/local/bin/ctlrender
  Reason: image not found
Trace/BPT trap: 5

The ctlrender binary seems to be linking against libImath-2_1.11.dylib whereas I have libImath-2_2.12.dylib. I wonder if anything needs rebuilding, or whether the brew script needs changing?

Update documentation to show that 32-bit floats are supported

It appears that ctlrender supports the writing of 32-bit tiffs, but this is currently unclear in the documentation.

When running ctlrender, if the flag -format tiff32 -force is used, then ctlrender will create a 32-bit tiff file, but this does not appear to be documented in the help for format. So, when ctlrender -help format is entered, -tiff32 should be on the list of supported output file types.

I anticipate that the most regular input to ctlrender will be a 16-bit half float exr, so there should probably be a note that the 32-bit tiff output must be used with a -force because the output file type is of a higher bit depth than the input file type.

ACES CTL modules with main function

Hello,

I'm trying to use the CTL C++ API and noticed that the ImfCtlApplyTransforms simplified API don't seems to work with ACES CTL anymore. The problem is that it expects a module with a function name matching the file name but the CTL define a main function.

I looked at the ctlrender code and found that it first checks for a main function and if not present search for a function matching the module name. I'm not sure if this could apply to the ImfCtlApplyTransforms API because in it's current state it first loads all the module, then map the tasks to thread in a pool. Will this work if we load several modules with a main function at once ?

Because I'm quite new to this codebase, is there a simple way to still use the simplified API while not modifying the CTL files ? If not I guess I should use something similar to the ctlrender code ?

Maximum data size for scatteredDataToGrid3D(...)?

Is there a maximum size for the data set in scatteredDataToGrid? Using ctlrender I run into trouble with the CTL below but when I truncate most of the data it works fine.

The error I get with the large data set: Assertion failed: (sigma > .0f), function kernel, file /tmp/ctl-sQsqh1/CTL-ctl-1.5.2/lib/IlmCtlMath/CtlRbfInterpolator.cpp, line 77.

CTL version synchronization

The version of CTL used within ctlrender may not be in synchronization with the official CTL libraries. These differences should be reconciled pushing useful new features back to the main CTL source.

Various minor typos in ctlrender usage text

In ctlrender -help: -output_scale is missing closing angle bracket

In ctlrender -help format: inconsistent use of periods at end of details for each format

In ctlrender -help scale: various copy/paste bugs. An unfinished statement warning about pitfalls of ADX values.

readme.md Ubuntu install instructions to run optional unit test do not work

Currently the readme.md Ubuntu install instructions have info about how to run optional unit tests, but the instructions don't work
the current instructions are:
sudo make checkcd
this gives error
make: *** No rule to make target 'checkcd'. Stop.
this issue can be fixed by changing the instructions to:
sudo make check
which will run the unit tests and actually finds that the unit tests are currently broken because of missing includes

ctlrender unittest fails on OSX

I am updating my homebrew formula for ctl to 1.5. When adding make check by default i ran into a unittest error:

Logfile: https://gist.github.com/cbenhagen/a1e10ab3164800492c76

You can test by running:

brew install https://github.com/cbenhagen/homebrew/raw/aces_container/Library/Formula/aces_container.rb
brew install -vd https://github.com/cbenhagen/homebrew/raw/ctl/Library/Formula/ctl.rb

ctlrender -help does not mention -force, -noalpha or -globalparam[123]

What's up with -globalparam[123], exactly? Are these setting the values of constants in the global namespace?

ctlrender scaling behavior and documention

The documentation for ctlrender’s scaling of integer content reads like this:

> ctlrender -help scale 
input and output value scaling:

    To deal with differences in input and output file bit depth, the ability
    to scale input and output values has been provided. While these options
    are primarily of use for integral file formats, they can be used with
    file formats that store data in floating point or psuedo-floating point
    formats. The default handling of the input and output scaling is variant
    on the format of the input (and output) file, but is intended to behave 
    as one expects.

    integral input files (integer tiff, integer dpx):
        If the '-input_scale' option is provided then the sample value from
        the file is *divided by* the specified scale.
        If the '-input_scale' option is not provided, then the input values
        are scaled to the range 0.0-1.0 (inclusive). For the purposes of
        this argument, DPX files are considered an integral file format,
        however ACES files are *not*. This is equivalent to specifying
        -input_scale <bits_per_sample_in_input_file>

    floating point input files (exr, floatint point TIFF, floating point
    dpx):
        If the '-input_scale' option is provided then the sample values
        are *multiplied by* the scale value.
        If the '-input_scale' option is not provided then the sample values
        from the file is used as-is (with a scale of 1.0).

    integral output files (integer tiff, integer dpx):
        If the '-output_scale' option is provided then the sample value from
        the CTL transformation is *multiplied by* the scale factor.
        If the '-output_scale' option is not provided, then the values of
        0.0-1.0 from the CTL transformation are scaled to the bit depth of
        the output file. For the purposes of this argument, DPX files are
        considered an integral file format, however ACES files are *not*.
        This is equivalent to specifying
        -output_scale <bits_per_sample_in_output_file>

    floating point output files (exr, floatint point TIFF, floating point
    dpx):
        If the '-output_scale' option is provided then the sample values
        are *divided by* the scale value.
        If the '-output_scale' option is not provided then the sample values
        from the file is used as-is (with a scale of 1.0).

    In all cases the CTL output values (after output_scaling) are clipped
    to the maximum values supported by the output file format.

The final sentences of the paragraphs on integral input and output files say This is equivalent to specifying -input_scale <bits_per_sample_in_input_file> and This is equivalent to specifying -output_scale <bits_per_sample_in_output_file>
Is that correct? I would think the equivalences was to specifying -input_scale 2^<bits_per_sample_in_input_file> - 1 and -output_scale 2^<bits_per_sample_in_output_file> - 1

If the -help scale output is incorrect, this should be fixed. In practice, actual behavior does not seem to correlate with the documentation. It would be helpful to have an example provided for each option to make clear when and how one might use each option.

Mac ilmbase files not included

Hello. I'm installing CTL on a Mac running OSX 10.8.4. Everything is installing correctly except for that when I run "make" in the build directory, the CTL files cannot find ilmbase. I get "/Users/oscar/Projects/CTL-1.5/CTL/lib/IlmCtl/CtlRcPtr.h:71:10: fatal error: 'IlmThreadMutex.h' file not found.
This is odd because when running cmake, Ilmbase is found. Somehow during compilation this found folder is not being included. I could link the directories or manually add the files but that defeats the purpose of discovering the issue. I also believe we had a similar issue on the other Mac in the lab so this might be a Mac specific bug. I'm pretty new to cmake so any suggestions would be appreciated.
Thanks.

scatteredDataToGrid() in detail

How does the scatteredDataToGrid() function create the source and destination grid? Does it sort the values properly before so there are no odd twists in the transform?

Reason I'm asking is I'm trying to match one macbeth to another by sampling the 24 source and destination patches and overall the results look pretty close, however the blacks get really lifted and the red patch that was matching pretty closely before got very desaturated. Does the interpolation of the grid towards the extreme boundaries of the grid cause the issues? Am I missing a step?

Thanks very much for any input!

Can't build on Ubuntu error: no match for ‘operator<<’

Hi,

I am using the following :

OS: Pop!_OS (Linux pop-os 5.4.0-7642-generic)
Cmake: cmake version 3.16.3
libopenexr-dev: 2.3.0-6ubuntu0.2

And i am trying to build the project by following those steps (from the README.md file):

$ mkdir build && cd build
$ cmake ..
$ make
$ sudo make install

And this is the error :

What am I missing here?

Thanks in advance

CTL git does not compile on windows

The first problem is that the constructor with ... is not recognized by the compiler. The problem appears on VC10, VC11 and VC12.

readme.md tiff install instuctions in Ubuntu 20.04 doesn't work

Currently the readme.md says TIFF can optionally be installed in Ubuntu with
sudo apt-get install libtiff4
but this doesn't seem to work anymore in Ubuntu 20.04 gives error
E: Unable to locate package libtiff4
this issue can be fixed by instead installing libtiff in Ubuntu with
sudo apt-get install libtiff-dev
I suggest the readme.md is updated accordingly

Compilation error caused by including OpenEXR related header

I am not able to compile the code because whenever a OpenEXR related header is included it throws an error. For example,

/home/jasjuang/CTL/lib/IlmCtl/CtlExc.h:66:24: fatal error: IexBaseExc.h: No such file or directory

Then I realized in CtlExc.h it's simply doing

#include <IexBaseExc.h>

but if I change the code to

#include <OpenEXR/IexBaseExc.h>

it passes compilation for this part. There are other numerous OpenEXR related header that throws the same compilation error? Why isn't there a OpenEXR prefix for all the included header? If I install it with sudo apt-get install libilmbase-dev, the header will showup at /usr/include/OpenEXR/IexBaseExc.h, if I install it from source, it will show up in /usr/local/include/OpenEXR/IexBaseExc.h, so no matter what there will be a OpenEXR prefix in the path for the header.

CTL git does not compile on windows (part 2)

CtlInterpreter.cpp is missing several includes and uses the unportable lrand48() function.

Here are the includes I had to add to make it portable.

ifdef _WIN32

#include \<io.h\>
#include \<stdio.h\>
#include \<stdlib.h\>
#include \<time.h\>
#define snprintf _snprintf

else

#include \<unistd.h\>

'-format aces' flag does not produce valid image files

Something appears to have broken in the '-format aces' output option.

ctlrender does not return an error, and the file appears to have been written successfully. However, the resulting file is unrecognized by both the operating system and by OpenEXR utilities such as exrheader.

I am on a Mac running OS 10.9.1, running the following:
-- found IlmBase, version 2.0.1
-- found TIFF, version 4.0.3
-- Found OpenEXR, version 2.0.1
-- Found AcesContainer, version 1.0.0

PATCH to fix ilmbase 2.3.0 compatibility in lib/IlmCtlSimd/CtlSimdInst.cpp

ilmbase and OpenEXR 2.3.0 change Iex::BaseExc to no longer derive from std::string, mentioned in the release notes here: https://github.com/openexr/openexr/releases/tag/v2.3.0

This causes a compilation error on lib/IlmCtlSimd/CtlSimdInst.cpp when it propagates a caught exception, because there is no longer an implicit conversion from Iex::BaseExc to std::string available.

It appears as though the fix were to use e.what() instead of e, which is what the attached patch does.

Currently there is no officially supported build mechanism for MS Windows

It has been suggested that using cmake might be an appropriate strategy for simplifying cross platform compiling.

ctlrender fails to link on mac

When building CTL on OS X 10.8.4 the build fails when linking ctlrender. The error says that there are undefined symbols for the x86_64 architecture. I've tried setting the compiler flags to -m64 and -arch x86_64 for gcc and g++ without success. The macbook is 64 bit. Here is the log below.

Nested structure initialization causes syntax error

Is initialization of nested structures supported? Should it be a syntax error?

ctlversion 1;

struct Test {
  float a;
  float b;
};

Test buildTest(float a, float b)
{
  Test test = { a, b };
  return test;
}

struct NestedStruct {
  Test test;
  float v;
};

void testFunction()
{
  // This works
  NestedStruct a;
  a.test = buildTest(1.0, 2.0);
  a.v = 3.0;

  // This fails.  Should the error be syntax error?
  Test b = buildTest(1.0, 2.0);
  NestedStruct c = { b, 3.0 };

  // This fails.  Should the error be syntax error?
  NestedStruct d = { buildTest(1.0, 2.0), 3.0 };
}

make check requires sudo on OS X

Running make check without sudo on OS X creates exceptions in tests 1 and 3. See issue #46 and https://gist.github.com/aforsythe/1e827a9b6f5f2ab2f2c0 for more details.

Segfault when a file is named something other than the function within it. Happens on @scottdyer's dev branch, likely happens in master?

input_scale: Option to disable scaling alpha?

input_scale scales alpha currently. This can lead to odd behaviour in many applications. Should there be an option to scale RGB and not alpha if desired?

Default behavior when input and output files are different bit depths seems unexpected

When input file is 10-bit, and output file is 16-bit OpenEXR, the following error is received:
"exception thrown (oops...): EXR files only support 16 or 32 bps at the moment."

This may actually be the intended behavior, but it seems like ctlrender should automatically scale correctly when the input format is an integral file and the output file is floating point. Adding an explicit -format exr16 works but the default behavior seems different than it was prior to CTL 1.5.

To reproduce, run the following line using the Sony F35 IDT available from aces-dev on the SonyF35.StillLife.dpx file available from the reference images 'camOrig' directory also available on aces-dev. For testing, I have used the 10-bit S-Log DPX file through the Sony F35 IDT.

This throws the exception:

ctlrender -ctl ~/aces-dev/transforms/ctl/idt/vendorSupplied/sony/F35/idt-SonyF35-10i.ctl -param1 aIn 1.0 SonyF35.StillLife.dpx  test_idt.exr

This will work:

ctlrender -ctl ~/aces-dev/transforms/ctl/idt/vendorSupplied/sony/F35/idt-SonyF35-10i.ctl -param1 aIn 1.0 SonyF35.StillLife.dpx  test_idt.exr -format exr16

CTL git is missing function exports

For building a proper DLL on windows, it is necesary to export all classes and public functions.
That needs an .h file with exports like:

if defined(OPENEXR_DLL)

#if defined(ILMCTL_EXPORTS)
        #define ILMCTL_EXPORT __declspec(dllexport)
    #define ILMCTL_EXPORT_CONST extern __declspec(dllexport)
#else
        #define ILMCTL_EXPORT __declspec(dllimport)
        #define ILMCTL_EXPORT_CONST extern __declspec(dllimport)
#endif

else

#define ILMCTL_EXPORT
#define ILMCTL_EXPORT_CONST extern const

endif

and then the classes defined like:

class ILMCTL_EXPORT RcObject
{
...
};

Is this project dead? openexr_ctl will not build with ctl and ignores --disable-ctltest

Using
CTL-ctl-1.5.2.tar.gz
CTL-openexr_ctl-1.0.1.tar.gz

--disable-ctltest is also ignored.

CTL crashes on Linux 4.15.0-39 (OpenEXR 2.3)

I updated my viewer to openexr 2.3 and latest ctl (with changes to compile on windows). On Windows all is peachy, but on Linux, as soon as two conforming CTL scripts are added to an image (say an IDT/ODT pair), I get a crash. Here's a partial stack trace of the crash:

CTL test program fails

Hi --

This is my first time compiling CTL and OpenEXR_CTL. I've compiled and installed the latest version of CTL just fine, but I get the following message when I try to build OpenEXR_CTL:

checking for OpenEXR... yes
Compiled and ran OpenEXR test program.
checking for CTL... no
*** Could not run the CTL test program, checking why...
*** The test program compiled and staticly linked, but did not run. This
*** usually means that the run-time linker is not finding CTL or finding
*** the wrong version of CTL.

*** If the linker is not finding CTL, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that
*** is required on your system.

*** Flags used by the test:
*** cflags: -g -O2 -I/usr/include/OpenEXR -I/usr/local/include/CTL
*** ldflags: -L/usr/local/lib

*** You can also run configure with --disable-ctltest to skip this test.
configure: error: The ctl test program failed.

The CTL libraries seem to be installed in the directories that the test is pointing to. I've never set LD_LIBRARY_PATH because it's usually not advisable. I've never modified ld.so.conf.

I'm building this on CentOS 6.3 using autoconf 1.11.

Any ideas on what I should do?

Thanks,

Haig
