Constructor Detail

FanCompress.FloatCompress

public FanCompress.FloatCompress(double[] array)

Construct a FanCompress object which deals in floats.

Parameters:

array - float[] array of coordinate pairs.

Method Detail

next_point

public boolean next_point(FanCompress.FanPoint p)

Get the next point.

Specified by:

next_point in class FanCompress

Parameters:

p - FanPoint

Returns:

boolean false if no more points.

save_point

public void save_point(double x,
                       double y)

Save coordinates. This routine coalesces adjacent points which have the same coordinates.

Specified by:

save_point in class FanCompress

Parameters:

x - coordinate

y - coordinate

set_coalesce_points

public void set_coalesce_points(double epsilon)

Save only unique coordinates. If several points are the same, then coalesce them into one point.

Specified by:

set_coalesce_points in class FanCompress

Parameters:

epsilon - threshold used to determine uniqueness of coordinates.

getArray

public double[] getArray()

Return a copy of the internal array. Invoke this method after running fan_compress() on this object.

Returns:

float[]
