enum | { Auto = -1, Nice = -2, NoThreads = 0 } |
Option base class for blockwise algorithms.
Attaches blockshape to ParallelOptions.
Shape const& getBlockShape | ( | ) | const |
Retrieve block shape as a std::vector.
If the returned vector is empty, a default block shape should be used. If the returned vector has length 1, square blocks of size getBlockShape()[0]
should be used.
TinyVector<MultiArrayIndex, N> getBlockShapeN | ( | ) | const |
Retrieve block shape as a fixed-size vector.
Default shape specifications are appropriately expanded. An exception is raised if the stored shape's length is incompatible with dimension N
.
BlockwiseOptions& blockShape | ( | const Shape & | blockShape | ) |
Specify block shape as a std::vector of appropriate length. If blockShape.size() == 0
, the default shape is used. If blockShape.size() == 1
, square blocks of size blockShape[0]
are used.
Default: Use square blocks with side length VIGRA_DEFAULT_BLOCK_SHAPE
.
BlockwiseOptions& blockShape | ( | const TinyVector< T, N > & | blockShape | ) |
Specify block shape by a fixed-size shape object.
BlockwiseOptions& blockShape | ( | MultiArrayIndex | blockShape | ) |
Specify square block shape by its side length.
