public class OMSpline
extends OMPoly

A splined OMPoly. With RENDERTYPE_LATLON mode, spline is computed on geographic locations, and then projected. Very few changes from OMPoly source code, just needed to calculate the spline before projecting in generate(). Look for HACK in source code ...

Constructor Detail

OMSpline

public OMSpline()

Default constructor.

OMSpline

public OMSpline(double[] llPoints,
                int units,
                int lType)

Create an OMSpline from a list of float lat/lon pairs.

NOTES:

• llPoints array is converted into radians IN PLACE for more efficient handling internally if it's not already in radians! For even better performance, you should send us an array already in radians format!
• If you want the curve to be connected (as a potato), you need to ensure that the first and last coordinate pairs are the same.

Parameters:

llPoints - array of lat/lon points, arranged lat, lon, lat, lon, etc.

units - radians or decimal degrees. Use OMGraphic.RADIANS or OMGraphic.DECIMAL_DEGREES

lType - line type, from a list defined in OMGraphic.

OMSpline

public OMSpline(double[] llPoints,
                int units,
                int lType,
                int nsegs)

Create an OMSpline from a list of float lat/lon pairs.

NOTES:

• llPoints array is converted into radians IN PLACE for more efficient handling internally if it's not already in radians! For even better performance, you should send us an array already in radians format!
• If you want the curve to be connected (as a potato), you need to ensure that the first and last coordinate pairs are the same.

Parameters:

llPoints - array of lat/lon points, arranged lat, lon, lat, lon, etc.

units - radians or decimal degrees. Use OMGraphic.RADIANS or OMGraphic.DECIMAL_DEGREES

lType - line type, from a list defined in OMGraphic.

nsegs - number of segment points (only for LINETYPE_GREATCIRCLE or LINETYPE_RHUMB line types, and if < 1, this value is generated internally)

OMSpline

public OMSpline(int[] xypoints)

Create an OMSpline from a list of xy pairs. If you want the curve to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

xypoints - array of x/y points, arranged x, y, x, y, etc.

OMSpline

public OMSpline(int[] xPoints,
                int[] yPoints)

Create an x/y OMSpline. If you want the curve to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

xPoints - int[] of x coordinates

yPoints - int[] of y coordinates

OMSpline

public OMSpline(double latPoint,
                double lonPoint,
                int[] xypoints,
                int cMode)

Create an x/y OMSpline at an offset from lat/lon. If you want the curve to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

latPoint - latitude in decimal degrees

lonPoint - longitude in decimal degrees

xypoints - int[] of x,y pairs

cMode - offset coordinate mode

OMSpline

public OMSpline(double latPoint,
                double lonPoint,
                int[] xPoints,
                int[] yPoints,
                int cMode)

Create an x/y OMSpline at an offset from lat/lon. If you want the curve to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

latPoint - latitude in decimal degrees

lonPoint - longitude in decimal degrees

xPoints - int[] of x coordinates

yPoints - int[] of y coordinates

cMode - offset coordinate mode
