[Insight-developers] PNG unsupported in modular ITK

[Xiaoxiao Liu]

Hi David,
  Sorry for the confusion.
  In your case, Luis's solutions are sufficient for now. Let me know if you
have problems in any of the options he provided.
  It makes  sense to enable common image formats by default (not just for
the test driver), as it used to be.  Note that we haven't use
 "CMake/EnablePreregisteredImageIOFactories.cmake"  yet in modularized ITK.
We will be working on it.

  My explanation by saying "If your testing code uses the test driver and
specifies "ITK-TestKernel" in your module dependency list, it should run
smoothly. " is only valid for testing in your own module.
(I was assuming you had created your own module and wanted to test the PNG
IO through test driver.)  You can ignore for now.  We will elaborate in our
wiki page later to show examples.
