Re: Digikam-devel Digest, Vol 58, Issue 81

Hi again.

Don't implement your own image loader - accept loaded image data.

Okay. Is that a Dimg ?
 

What is the configuration data for which you accept a directory? Which options
are set there, and from whom? Or is this where the training data is stored?

 
The configDir is a directory in which libface currently looks for the libface.xml file - that's the one which stores the training data.

I also see a hardcoded path to opencv installation, which is something which
will break in real-life...

Then I guess I'll tell libface to look for a configuration file in the config directory, which will store the opencv path. If you could tell me how to find where opencv is located in a system, that would be great.

We will want a nice Qt-based layer, but I dont see any problems right now why
this shouldn't be possible on-top.

 
Sure.

But please bear with me, I don't have time to code for at least 5 days...

Regards,

Use pkg-config. There are cmake macros for this.

In the simplest case (and API agnostic) it is a uchar* pointer with a given
width, height, in a defined pixel format (RGBA or BGRA).
I assume you'll have to allocate and IPImage and copy the data in any case.

All right then.

As Johannes said, you already use CMake, which can do this for you.
See the CMakeLists.txt files of kipi-plugins and the removeredeyes kipi
plugins for an example.

No hurry. Take your time.
