| float | minLength |
The rectangular locations are represented by its position in an image or channel, an orientation, the length at the orientation direction (maxLenght), and the length at the perpendicular direction (minLength).
The difference to lti::location is that the regions are considered rectangular. Two lengths are needed, where the orientation angle is always given for the maxLength.
You can get rectangular locations with the lti::boundingBox functor, and used them to check if objects overlap or not.

|
|
copy the other location into this rectLocation. The radius of the location will be assumed as the maxLength and minLength. |

Check if the given point can be considered within the rectLocation.

copy operator

returns the square of the distance between the borders of two locations or zero if they overlap or if one of the locations lies inside the other one.

Get the area of this location (maxLength*minLength).

|
|
operator !=
|
|
|
Comparition operator. A rectLocation is smaller than another one if its area is smaller, or in case of equal areas, if the position is smaller, i.e. if it has smaller y-coordinate, or in case of equal y-position, if it has smaller x-coordinate. |

operator ==
|
|
|
Comparition operator. A rectLocation is greater than another one if its area is greater, or in case of equal radii, if the position is greater, i.e. if it has greater y-coordinate, or in case of equal y-position, if it has greater x-coordinate. |
