Constructor Detail

ESRIPointRecord

public ESRIPointRecord(double x,
                       double y)

Initializes this point from the given point.

Parameters:

x - the x coordinate

y - the y coordinate

ESRIPointRecord

public ESRIPointRecord(byte[] b,
                       int off)
                throws java.io.IOException

Initialize a point record from the given buffer.

Parameters:

b - the buffer

off - the offset into the buffer where the data starts

ESRIPointRecord

public ESRIPointRecord(byte[] b,
                       int off,
                       javax.swing.ImageIcon imageIcon)
                throws java.io.IOException

Initialize a point record from the given buffer.

Parameters:
