Public Member Functions | |
vtkImageStencilRaster (const int wholeExtent[2]) | |
Create a raster with the specified whole y extent. | |
~vtkImageStencilRaster () | |
Destructor. | |
void | PrepareForNewData (const int allocateExtent[2]=nullptr) |
Reset the raster to its original state, but keep the same whole extent. | |
void | 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. | |

Insert a line into the raster, given the two end points. | |
Protected Member Functions | |
void | PrepareExtent (int ymin, int ymax) |
Ensure that the raster is initialized for the specified range of y values, which must be within the Extent. | |

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.
