[vtk-developers] vtkImageReslice - counterpart to write a slice to a volume

[Steve Pieper]

Hi Tobias -

I faced the same issue with the label map editor in slicer so I wrote a
class called vtkImageSlicePaint.  You specify a mask image data and the
corner points of it in the target label volume and it rasterizes the mask
into target volume.

It also does a couple other things that I needed, like conditionally
applying the mask depending on a threshold condition of a background
grayscale image and also conditionally on whether the label map already has
a non-zero value.

HTH,
Steve

ps.
The user documentation for the tool that uses it is here:
