[ITK] pixeltype define and template lost in python warped ITK

[Bradley Lowekamp]

Hello,

2) I believe that is the error message when the the filter hasn't been instantiated with that template argument. Poke around itk.BinaryImageToLabelMapFilter's dict interface, some method along the lines 'keys()' should give you a list of the types that have been compiled and can be created.

hope this helps,
Brad

Then I take itk.Image.F3, then it get a range of '-3.40282346639e+38  3.40282346639e+38' . The grey value of my image is 0-9000 . How could I read it proprietorially?
