Public Member Functions | |
Frame () | |
Default constructor. | |
Frame (double xMin, double yMin, double xMax, double yMax) | |
this one is dangerous: you may swap the 2 middle arguments. | |
Frame (const Point &lowerLeft, const Point &upperRight) | |
typical use: Frame(Point(xmin,ymin),Point(xmax,ymax)) | |
double | getWidth () const |
size along x axis | |
double | getHeight () const |
size along y axis | |
Point | getCenter () const |
Center of the frame. | |
Frame | operator* (const Frame &right) const |
intersection of Frame's. | |
Frame & | operator*= (const Frame &right) |
intersection of Frame's | |
Frame | operator+ (const Frame &right) const |
union of Frames | |
Frame & | operator+= (const Frame &right) |
union of Frames | |
void | cutMargin (double marginSize) |
shrinks the frame (if marginSize>0), enlarges it (if marginSize<0). | |
void | cutMargin (double marginX, double marginY) |
shrinks the frame (if marginSize>0), enlarges it (if marginSize<0). | |
bool | operator== (const Frame &right) const |
necessary for comparisons (!= is defined from this one implicitely) | |
bool | operator!= (const Frame &right) const |
comparison | |
Frame | rescale (double factor) const |
rescale it. The center does not move. | |
double | getArea () const |
bool | inFrame (double x, double y) const |
inside? | |
bool | inFrame (const Point &point) const |
same as above | |
double | minDistToEdges (const Point &point) const |
distance to closest boundary. | |
void | print (std::ostream &out) const |
Public Attributes | |
double | xMin {} |
coordinate of boundary. | |
double | xMax {} |
double | yMin {} |
double | yMax {} |

rectangle with sides parallel to axes.
when Frame's are used to define subparts of images, xMin and xMax refer to the first and last pixels in the subimage
