Methods
No description
Old style constructor
Calculates distance between a point ad a lined defined by the two points passed in argument.
Project the point from "in" projection (1st argument) to "out" projection (2nd argument). Returns MS_SUCCESS/MS_FAILURE.
Set X,Y coordinate values.
Set X,Y,Z coordinate values.

final float
distanceToLine(pointObj $p1, pointObj $p2)
Calculates distance between a point ad a lined defined by the two points passed in argument.
final float
distanceToPoint(pointObj $poPoint)
Calculates distance between two points.
final float
distanceToShape(shapeObj $shape)
Calculates the minimum distance between a point and a shape.
final int
draw(mapObj $map, layerObj $layer, imageObj $img, int $class_index, string $text)
Draws the individual point using layer. The class_index is used to classify the point based on the classes defined for the layer.
The text string is used to annotate the point. (Optional) Returns MS_SUCCESS/MS_FAILURE.
final int
project(projectionObj $in, projectionObj $out)
Project the point from "in" projection (1st argument) to "out" projection (2nd argument). Returns MS_SUCCESS/MS_FAILURE.
final int
setXY(float $x, float $y, float $m)
Set X,Y coordinate values.
.. note:: the 3rd parameter m is used for measured shape files only. It is not mandatory.
final int
setXYZ(float $x, float $y, float $z, float $m)
Set X,Y,Z coordinate values.
.. note:: the 4th parameter m is used for measured shape files only. It is not mandatory.
