Two dimensional size object.
Specializes Diff2D for the specification of a 2-dimensional extent, in contrast to a point or position (for the latter use Point2D).
#include <vigra/diff2d.hxx>
Namespace: vigra
| Size2D | ( | ) |
Default Constructor. Init point at position (0,0)
| Size2D | ( | int | width, |
| int | height | ||
| ) |
Construct point at given position.
| int width | ( | ) | const |
Query the width.
| int height | ( | ) | const |
Query the height.
| void setWidth | ( | int | w | ) |
Change the width.
| void setHeight | ( | int | h | ) |
Change the height.
| int area | ( | ) | const |
Returns width()*height(), the area of a rectangle of this size.
| Size2D operator- | ( | ) | const |
Unary negation.
