[Insight-users] Pluggable Factories

[Luis Ibanez]

Hi Ron,

There are two ways of registering your own ImageIO factories


1) In your main.cxx file (or any file where you
    have your main() function) invoke


    ObjectFactoryBase::RegisterFactory( XYZImageIOFactory::New() );

    where XYZ is the name of your file format.

    This is completly equivalent to call:


    XYZImageIOFactory::RegisterOneFactory();

    (if you see the definition of RegisterOneFactory in
     the .h files in Insight/Code/IO, you will find that
     it simply invoke ObjectFactoryBase::RegisterFactory)




OR



2) You can have your factory be automatically registered
    by modifying the file:

            ImageIOFactory.cxx

    in the directory:

          Insight/Code/IO

    starting in line 95, you will see the other file formats.
    (of course you will have to add the XXXImageIOFactory.h
    file to the #include lines).


Regards,


     Luis
