com.bbn.openmap.omGraphics.OMLine
Graphic object that represents a simple line.
The OMLine is used to create simple lines, from one point on the window to the other. If you want to have a line with several parts, use OMPoly as a polyline with no fillColor.

Create a line from lat lon points. |
|
OMLine(float lat_1,
float lon_1,
int x1,
int y1,
int x2,

int |
getNumSegs()
Get the number of segments of the lat/lon line. |
int[] |
getPts()
Get the xy values of the end points of the line in an array of ints - x1, y1, x2, y2 . |
boolean |
isPolyline()
Check to see if this line is a polyline. |
void |
