Two dimensional point or position.
Specializes Diff2D for the specification of a 2-dimensional point or position, in contrast to an extent (for the latter use Size2D).
#include <vigra/diff2d.hxx>
Namespace: vigra
The iterator's value type: a coordinate.
the iterator's index reference type (return type of iter[diff]
)
Point2D | ( | ) |
Default Constructor. Init point at position (0,0)
int px | ( | ) | const |
Query the points' x coordinate
int py | ( | ) | const |
Query the points' y coordinate
Read point coordinate at an offset.
index_reference operator[] | ( | Diff2D const & | offset | ) | const |
Read point coordinate at an offset.
