This is a helper class for stencil creation.
It is a raster with infinite resolution in the X direction (approximately, since it uses double precision). Lines that represent polygon edges can be drawn into this raster, and then filled given a tolerance.

| vtkImageStencilRaster::vtkImageStencilRaster | ( | const int | wholeExtent[2] | ) |
Create a raster with the specified whole y extent.
| vtkImageStencilRaster::~vtkImageStencilRaster | ( | ) |
Destructor.
| void vtkImageStencilRaster::PrepareForNewData | ( | const int | allocateExtent[2] = nullptr | ) |
Reset the raster to its original state, but keep the same whole extent.
Pre-allocate the specified 1D allocateExtent, which must be within the whole extent.
| void vtkImageStencilRaster::InsertLine | ( | const double | pt1[2], |
| const double | pt2[2] | ||
| ) |
Insert a line into the raster, given the two end points.
| void vtkImageStencilRaster::FillStencilData | ( | vtkImageStencilData * | data, |
| const int | extent[6], | ||
| int | xj = 0, |
||
| int | yj = 1 |
||
| ) |
Fill the specified extent of a vtkImageStencilData with the raster, after permuting the raster according to xj and yj.

Ensure that the raster is initialized for the specified range of y values, which must be within the Extent.

Insert an x point into the raster.
If the y value is larger than the y extent, the extent will grow automatically. The parameter i indicates which of the two internal rasters is to be used.
