Interested in options in drawing 1 bit per pixel images from slice geometry

When you say “outer” contour, does this imply there is also an “inner” contour?

I’m not sure if it fits your requirements, but VTK has a class called vtkPolyDataToImageStencil that slices polydata and generates a stack of binary images. However,

  1. It uses a simple inside/outside check: if the pixel is on the “inside” side the contour, it’s on, and if it’s on the “outside” side, it’s off. There is no percentage calculation.
  2. The output data (vtkImageStencilData) isn’t 1 BPP, it’s actually a run-length compression of a 1BPP image. A custom class would be needed to write it out to a TIFF.
