Member Function Documentation

virtual void itk::OctreeBase::BuildFromBuffer ( const void *  buffer,
const int  xsize,
const int  ysize,
const int  zsize 
) [pure virtual]

Build an Octree from an Image's pixel buffer.

Method needed for ImageIO class, which has no handle on image, just the pixel buffer.

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual const char* itk::OctreeBase::GetColorTable ( ) const [pure virtual]

Get the ColorTable Pointer

Returns color table pointer for this tree.

Each Octree has an array of char whose size = the number of color table entries. Each Node in the Octree points either to 8 sub-nodes, or into the ColorTable; The color table isn't actually used to hold data; it simply provides a range of unique addresses that are distinct from the address of any valid subtree.

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual int itk::OctreeBase::GetColorTableSize ( ) const [pure virtual]

Get the size of the Color Table

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual unsigned int itk::OctreeBase::GetDepth ( ) [pure virtual]

Get tree depth.

Depth represents x, for the smallest 2^x >= largest image dimension

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual OctreeNode* itk::OctreeBase::GetTree ( ) [pure virtual]

Get the actual tree base

Returns the tree, or 0 if the Octree isn't built yet

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual unsigned int itk::OctreeBase::GetWidth ( ) [pure virtual]

Get tree width.

Width == smallest 2^x >= largest image dimension i.e. 2^Depth == Width

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual void itk::OctreeBase::SetDepth ( unsigned int  depth) [pure virtual]

Set the depth, e.g. when reading tree from a file.

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.

virtual void itk::OctreeBase::SetWidth ( unsigned int  width) [pure virtual]

Set width, e.g. when reading from a file.

Implemented in itk::Octree< TPixel, ColorTableSize, MappingFunctionType >.
