Started at least 10 years ago in 2011 with T8977: New ipPic-Free design of PixelType, direct usage of IpPic has been removed from MITK. However, there are still a few dangling references, dead code, comments, and outdated documentation around. And of course the actually last functioning but deprecated usage of IpPic in the legacy pic IO.
IpPic or parts of it are still used by IpFunc so indirectly the library is still necessary but we should finally make the cut for direct usage.
I already replaced the last pic files in rMD MITK-Data with nrrd files. After this "task" is merged, a second commit to rMD MITK-Data must follow to remove the unused pic files. I split it this way that current Differentials still succeed to build that are not based on the latest changes.
