Geo::ShapeFile::Point - Geo::ShapeFile utility class.
use Geo::ShapeFile::Point; use Geo::ShapeFile; my $point = Geo::ShapeFile::Point->new(X => 12345, Y => 54321);
This is a utility class, used by Geo::ShapeFile.
This is a utility class, used by Geo::ShapeFile to represent point data, you should see the Geo::ShapeFile documentation for more information.
Nothing.
This module uses overloaded operators to allow you to use == or eq to compare two point objects. By default points are considered to be equal only if their X, Y, Z, and M attributes are equal. If you want to exclude the Z or M attributes when comparing, you should use comp_includes_z or comp_includes_m when importing the object. Note that you must do this before you load the Geo::ShapeFile module, or it will pass it's own arguments to import, and you will get the default behavior:
DO: use Geo::ShapeFile::Point comp_includes_m => 0, comp_includes_z => 0; use Geo::ShapeFile; DONT: use Geo::ShapeFile; use Geo::ShapeFile::Point comp_includes_m => 0, comp_includes_z => 0; (Geo::ShapeFile already imported Point for you, so it has no effect here)
Creates a new Geo::ShapeFile::Point object, takes a hash consisting of X, Y, Z, and/or M values to be assigned to the point.
Set/retrieve the X, Y, Z, or M values for this object.
Get the X, Y, Z, or M values for this object. Slightly faster than the dual purpose set/retrieve methods so good for heavy usage parts of your code.
These methods are provided for compatibility with Geo::ShapeFile::Shape, but for points simply return the X, Y, Z, or M coordinates as appropriate.
Returns the distance between this point and the specified point. Only considers the two-dimensional distance. Z and M values are ignored.
Returns the bearing (in degrees from north) from this point to some other point. Returns 0 if the two points are in the same location.
