Subject: [Ctk-developers] CTK,
	color consistency and ICC profiles (and recent color summit)
Message-ID: <51FA77A3.9010908@dclunie.com>

Hi all

I was wondering if any CTK developers had any particularly
interest in color consistency, management and in particular
the use of ICC profiles and color calibrated displays.

Since DICOM images can (though don't often) contain embedded
ICC profiles, and each image may contain a different profile,
to display these side-by-side consistently would require CTK
to take this into account (e.g., like Photoshop does).

Other requirements might include when importing non-DICOM files
like JPEGs, if any ICC profile is embedded in the JPEG bitstream,
it should be accounted for.

Likewise, color images generated in CTK and saved, regardless
of format, should probably be tagged with an appropriate ICC
profile, if the format permits it.

We recently had a summit on the subject, the presentations
and the recordings of which are available at:

http://www.color.org/events/medical/presentations.xalter
http://www.color.org/events/medical/medical_summit_2013.xalter
http://www.color.org/events/medical/medical_summit_2013_abstracts.xalter
http://www.fda.gov/MedicalDevices/NewsEvents/WorkshopsConferences/ucm342138.htm

There is also a new ICC Medical Imaging Working Group:

http://www.color.org/groups/medical_imaging_wg.xalter

David

PS. I sent a similar message to the VTK list, so to the extent
that VTK were to implement color management, CTK would presumably
inherit it.

Subject: [Ctk-developers] Quazip, zlib dependency
Message-ID: <CAOVq=oNmNqP1m9Jf6C45Y+od=7tqSPanMphr5RwsGyOuV-_5xQ@mail.gmail.com>

Hi,

we discussed in December that Quazip could be used as an external project
of CTK for zip support, e.g. for the XNAT plugin. Sascha set up a CMake
file that pulls it and builds it as an external project.

It works fine on Linux and Mac, but not on Windows, because Quazip depends
on zlib that is not installed on Windows systems by default.

So the question is, how to handle this situation? Should CTK build also
zlib as an external project, or we can say that zlib must be installed on
the system?

Currently, the zip/unzip functionality of our XNAT plugin has not been
pulled up to CTK, it is done in our application. Should it be kept like
this? If yes, the question is irrelevant.

What do you suggest?

Cheers,
Miklos

Hi,

Makes sense. On windows, zlib could be superbuild by CTK. It is already
CMake'ified and available within the commontk organization. You could look
here for an example of external project:
https://github.com/Slicer/Slicer/blob/master/SuperBuild/External_zlib.cmake

Hi Jc,

I added zlib as an external project and it builds fine, but there are two
issues. The first is that QuaZip is still linked against the zlib in the
system.

The second is that I get the following error at the CTK configure step
(after zlib and QuaZip has been built).

--------------------------------------------------------------------------------------------
CMake Error at CMakeLists.txt:891 (find_package):
  By not providing "Findzlib.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "zlib", but
  CMake did not find one.

  Could not find a package configuration file provided by "zlib" with any of
  the following names:

    zlibConfig.cmake
    zlib-config.cmake

  Add the installation prefix of "zlib" to CMAKE_PREFIX_PATH or set
  "zlib_DIR" to a directory containing one of the above files.  If "zlib"
  provides a separate development package or SDK, be sure it has been
  installed.
--------------------------------------------------------------------------------------------

As I see, there is no zlibConfig.cmake in the cmake-ified project, but I
guess you can build Slicer in spite of this.

What is the trick? :)

Cheers,
Miklos

Hi Everyone -

It looks like we're getting a critical mass of attendees for the London
hackfest - remember to get your travel arrangement made and add your name
to the Attendees table on the wiki page.

If you can't be there in person but want to participate, add your name to
the table of google hangout participants.  We'll set up hangouts like we
did for the Kingston hackfest.

Cheers!

Hi all, I was working in other areas of my project and now I would like to
retake CTK. I have a simple qt+vtk+itk example. I want to add the double
slider widget. How can I cmake that? If you have an example that would be
great, I haven't found any.
Thanks

Hi Jose,

Have you looked at http://www.commontk.org/index.php/Getting_Started ?
There is a link to an example <https://github.com/commontk/Examples> of

Hi, this is a simple question. I am trying to add CTK widgets to QT
Designer as said in
http://www.slicer.org/slicerWiki/index.php/Documentation/4.1/Developers/Tutorials/QtDesignerbut
have not succeeded. I have qt built in a Build folder and then
installed in /opt/qt folder  (in ubuntu). I copied
CTK-build/bin/designer/libCTK* to /opt/qt/plugins/designer but it doesn't
work.
What can I do?

Thanks

When you are in Qt Designer, what does the "Help -> About Plugin" dialog
says? Any error message for the CTK plugins?

The plugins need the CTK libraries libCTKCore.so, libCTKWidgets.so... to be
able to load in Qt Designer.
You can copy them in /opt/qt/plugins/designer, you can create symbolic
links (should probably be the best solution here) or you can set the
LD_LIBRARY_PATH env variable.

When you get it to work (feel free to ask more questions if you are
blocked), can I ask you for a favor? Can you please update the CTK wiki
with instructions to get CTK widgets within QtDesigner? Extending the
Getting started wiki page would be a good start.

Thanks,
Julien.

Hi,

I have created a pull request for the SlicerExecutionModel that could
use review [1].  This feature, which can optionally be enabled via
CMake, adds serialization/deserialization via JSON files capabilities
to CLI's.

>From the pull request:


Motivation
----------

The ability to store, restore, and programmatically manipulate
algorithm parameters has many benefits.  The set of parameters used in
an analysis can be archived for future reference or shared for
reproducibility purposes.  A collection of parameter sets tuned for
particular types of input data can be stored and restored.  If a
standard file format with libraries easily accessible across
programming languages is used to serialize the parameters, automated
exploration of the parameter space is possible.

This branch adds command line flags to serialize and deserialize the
parameters used by the Command Line Interface (CLI) in the JSON_ file
format.

Building
--------

Check out the *ParameterSerializer* branch of this repository.  During
CMake configuration, set *SlicerExecutionModel_USE_SERIALIZER* to *ON*
and the build paths to the jsoncpp-cmake_ and ParameterSerializer_
projects with *JsonCpp_DIR* and *ParameterSerializer_DIR*.

Implementation
--------------

Two new flags will be automatically added to all CLI's:

1) --serialize <std::string>
2) --deserialize <std::string>

The *--serialize* flag specifies the path to a JSON file where all the
parameters used in the current analysis will be **archived**.  The
*--deserialize* flag specifies the path to a JSON file created by the
*--parametersarchive* in a previous execution.  Parameters from the
previous execution will then be **restored** for the current analysis.

While the layout of the JSON file reflects the self-descriptive
metadata of the CLI XML file, it also contains *Value* entries for
each parameter.

Since parameters can be specified in different ways, an order of
precedence determines which specification is used in the analysis.
This order is, from highest to lowest:

1) Command line arguments.
2) Parameters restored from the JSON file.
3) The default parameter value in the CLI XML file.

Required parameters, such as positional arguments, must always be
specified on the command line even if `--deserialize` is given.



Your feedback is welcome.

Thanks,
Matt

Hi, I am still not able to do it. I think my qtcreator was installed (I
don't remember) from debian package but built from source. When I "locate"
qtcreator appers in /usr/lib... so I copied all the CTK .so files in
/usr/lib/x86_64-linux-gnu/qtcreator/plugins/ where I can see other nokia
plugins. Is it correct?

I partially did it. I tried using
http://qt-project.org/doc/qtcreator-2.6/adding-plugins.html and I opened
/opt/qt-4.8.4/bin/qtdesigner and I could see CTK plugins. But from normal
qtcreator (/usr...) I cannot see them not load a ctk form previouly made in
qtdesigner. I am using qt creator 2.4.1, is that the problem?

I cannot see it in qtcreator, but works fine in qtdesigner and it builts
and runs correctly. I think this is enough for developing. Thanks

That's great you managed to load the CTK widgets in QtDesigner!
Can you populate the following wiki page with the steps you did to have the
widgets in the designer:
 http://www.commontk.org/index.php/CTK_In_QtDesigner

I can't really help for QtCreator as I don't personally use it. My guess is
that it might be missing dependencies. You might want to try with the
QT_PLUGIN_PATH environment variable otherwise.

Thanks,
Julien.

Subject: [Ctk-developers] Linking a shared library within a plugin
Message-ID: <CAFfsywjnDnKqbriZw1aOeprvJ-bkHC4c2Yigp__gr8uJgUdhmw@mail.gmail.com>

Hi,
we are trying to link a shared library to connect to tracker from a plugin.
We know, that the code that calls the .so library works in a test
application and also in the main method of our CTK application. After we
have added our code to the plugin and linked it to the .so library, we can
link and compile the code without errors, but we don't get a connection to
the tracker.
The cmakelists code to link the .so file in our test application is
TARGET_LINK_LIBRARIES(optoExtern ${OPTOTRAK_LIBRARY})
(${OPTOTRAK_LIBRARY} is the library path, optoExtern the project name)

The cmakelists code to link the .so file in our plugin:
ctkMacroBuildPlugin(
  NAME ${PROJECT_NAME}
  EXPORT_DIRECTIVE ${PLUGIN_export_directive}
  SRCS ${PLUGIN_SRCS}
  MOC_SRCS ${PLUGIN_MOC_SRCS}
  UI_FORMS ${PLUGIN_UI_FORMS}
  INCLUDE_DIRECTORIES ${Plugin_SOURCE_DIR}
  RESOURCES ${PLUGIN_resources}
  TARGET_LIBRARIES ${PLUGIN_target_libraries} ${OPTOTRAK_LIBRARY}
)

Has anyone an idea how to link external shared libraries within a plugin
properly?

Best regards,
Florian Ganglberger

Based on my experience ... even after setting QT_PLUGIN_PATH I couldn't
load plugin located in multiple folder using QtCreator.

On the other hand, setting QT_PLUGIN_PATH  is know to work QtDesigner

Possible hack: Manually create symlink in the expected folder

Hi Florian,
If it build without problem, did you try using a debugger to try to
understand what s wrong?

Hi,

I don't have experience with QtCreator installs from e.g. a Debian 
package, but the designer plug-ins definitely need to go in a "designer" 
subdirectory, even when copied to a system path. On my system with a 
custom QtCreator install, that would be

<qtcreator-install-path>/bin/designer

but I didn't test/verify it myself right now.

Best,
Sascha

Hi Jc,
we can't really use a debugger, since we don't have the code for the shared
library, only the header files. The methods of the shared library is
definitely called, because we get an error message that a connection to the
tracker can't be established. Can it be a problem, that the plugins are
also shared libraries? We'll write a shared library that calls the tracker
today, so we can see if the problem depends on calling the tracker-library
from a shared library or if it is ctk specific.

Additional information: As far as we know, the tracker library was written
in C (and not in C++)

Thanks for your help,
Florian

Hi Jc,
we've built a new shared library which calls our shared-tracker-library. It
works perfectly outside of our plugin and the tracker can connect. As soon
as we link the new shared library into the plugin, we have our connection
problem again. It calls the function, produces all the output, but can't
connect. So we can say that the* shared tracker library works for:*
*- a normal example program*:   example program --> shared tracker library
*- the main method of our ctk app:*   ctk app --> shared tracker library
*- called from a "normal" shared library: *   example program --> "normal"
shared library  --> shared tracker library

*and not for:*
*- the plugin* (which is a shared library): ctk plugin --> shared tracker
library
*- a call from a shared library which is called by the plugin*:  ctk
plugin --> "normal" shared library  --> shared tracker library

Actually we have no idea, why it doesn't work....

Thanks for your help,
Florian

Hi Florian,

this all sound really strange...

as you have noted already yourself, plug-ins are also just shared 
libraries, which are loaded dynamically at runtime. If I understood you 
right, in the case of linking the proprietary tracker library to the 
plug-in, the plug-in starts successfully but the tracker library reports 
a runtime error. Is that correct?

The only difference of which I can think of (compared to the working 
cases you mentioned), is that the plug-in is loaded via "dlopen" (on 
POSIX systems) using the QLibrary class. Depending on the Plugin 
Framework options

http://www.commontk.org/docs/html/structctkPluginConstants.html#a29af0cac606ca29ea8d66d342d05060e

different load hints are passed to QLibrary 
(http://qt-project.org/doc/qt-4.8/qlibrary.html#loadHints-prop). These 
load hints might affect symbol resolutions of subsequently loaded 
libraries, like your tracker library.

But if all this really relates to your actual problem is not clear to 
me, sorry.

Best,

Sascha

Hi Sascha,
we've figured out, that the tracker library uses another library for the
initialization of the connection. The problem was, that the symbols of this
library couldn't be resolved. This leads to the assumption, that the plugin
framework links correctly to a shared library, but not to shared libraries,
that are used by the first shared library.
By loading the tracker library with your
suggestion (ExportExternalSymbolsHint), it was possible to initialize our
tracker correctly! Thank you very much for your help!

For people with the same problem, this is the code to load a class from a
shared library which depends on other shared libraries (from a ctk plugin):

QLibrary library("library.so");
library.setLoadHints(QLibrary::ExportExternalSymbolsHint);
library.load();
if(library.isLoaded()){
    MyClass * c = new MyClass;
    if(c){
       // dostuff
    }
}

and for a function:

QLibrary myLib("library.so");
library.setLoadHints(QLibrary::ExportExternalSymbolsHint);
library.load();
typedef void (*MyPrototype)();
MyPrototype myFunction = (MyPrototype) myLib.resolve("mysymbol");
if (myFunction)
    myFunction();

Note, that you have to link your library.so also in the CMakeLists.txt with
target_link_libraries.

Best regards,
Florian
