[ITK-dev] WarpImageFilter wrong output

[haratron]

Hello and happy new year,

I'm using the WarpImageFilter from here:
http://www.itk.org/Wiki/ITK/Examples/Registration/WarpImageFilter

I have original.png that I'm using as the movingImage and I'm creating
another one ("empty" image filled with white color, size 1800x1800) that is
the fixedImage.

The problem is that a blank image filled with black is created instead of
the warped image that is expected.

My full WarpImageFilter.cxx file (includes changes from the original
example code):

What am I doing wrong?

John
