It should use the current CPU's endianness if you specify

   image.endian(NativeEndian);

The big endian format is used by default because at one time virtually 
all DPX files were big endian and there was substantial software which 
did not know how to parse little endian.

I agree that it would be nice if image.endian() returned the 
endianness of the file which was just read.
