Defines lower and upper valid indices.
Is part of the basic characteristic of each Data instance. Encapsulates a start and end index. Size and Dimension are directly extracted from Extent.
Extent | ( | ) |
default constructor
initialize with Size
The extent will go from -(size-1)/2 to (size-1)/2 for odd sizes, and from -(size/2-1) to size/2 for even images
not explicit on purpose, facilitates easier creation code
bool Contains | ( | const Point & | p | ) | const |
Returns true if the given point is within extent.
bool Contains | ( | const Extent & | e | ) | const |
Returns true if the given exten is within extent.
