Hello, Unfortunately, nobody has yet fixed Alien::FreeImage (this problem is known and why PDL does not test against PDL::IO::Image at this time) and I have not contacted the author. I might be able to help, but not immediately. Which functionality of PDL::IO::Image do you need? It may be built-in to PDL already.
