Named vectorized comparison functions | |
Note that these return CoordinateExpr, not bool. Unlike most arithmetic and assignment operators, scalar interoperability is provided for comparisons; expressions like if (all(point.gt(0))) ... are both ubiquitous and easy to interpret. | |
CoordinateExpr< N > | eq (Point< T, N > const &other) const |
CoordinateExpr< N > | eq (T scalar) const |
CoordinateExpr< N > | ne (Point< T, N > const &other) const |
CoordinateExpr< N > | ne (T scalar) const |
CoordinateExpr< N > | lt (Point< T, N > const &other) const |
CoordinateExpr< N > | lt (T scalar) const |
CoordinateExpr< N > | le (Point< T, N > const &other) const |
CoordinateExpr< N > | le (T scalar) const |
CoordinateExpr< N > | gt (Point< T, N > const &other) const |
CoordinateExpr< N > | gt (T scalar) const |
CoordinateExpr< N > | ge (Point< T, N > const &other) const |
CoordinateExpr< N > | ge (T scalar) const |
Arithmetic operators | |
No scalar interoperability is provided for Point arithmetic operations. | |
Extent< T, N > | operator- (Point< T, N > const &other) const |
Point< T, N > | operator- (Extent< T, N > const &other) const |
Point< T, N > | operator+ (Extent< T, N > const &other) const |
Point< T, N > & | operator+= (Extent< T, N > const &other) |
Point< T, N > & | operator-= (Extent< T, N > const &other) |

Explicit converting constructor.
Converting from floating point to integer rounds to the nearest integer instead of truncating. This ensures that a floating-point pixel coordinate converts to the coordinate of the pixel it lies on (assuming the floating point origin is the center of the first pixel).

Return a fixed-size Eigen representation of the coordinate object.
The fact that this returns by const reference rather than by value should not be considered part of the API; this is merely an optimization enabled by the implementation.
