Package com.luciad.view.lightspeed.label

Class TLspLabelPlacement

java.lang.Object

com.luciad.view.lightspeed.label.TLspLabelPlacement

public class TLspLabelPlacement
extends Object

A label placement defines a location of a label. This location is specified by an ALspLabelLocation and label bounds.

The label bounds is a rotated rectangle expressed in view coordinates (pixels), see illustration.

A TLspLabelPlacement is always created for a specific TLspLabelID, which is also stored inside this class.

Since:

2012.0

Creates a new label placement for the given label, with the given location, visibility and rotated bounds (in view coordinates).

Parameters:

aId - the label.

aLocation - the location.

aVisible - the visibility.

aX - the x coordinate of the upper left corner of the bounds, in view coordinates.

aY - the y coordinate of the upper left corner of the bounds, in view coordinates.

aWidth - the width of the bounds, in view coordinates.

aHeight - the height of the bounds, in view coordinates.

aRotation - the rotation of the bounds, given in radians, clockwise and with 0 radians at 3 o'clock.
