Interface Coordinates

All Known Subinterfaces:

WorldCoordinates

All Known Implementing Classes:

ImageCoords, WorldCoords

public interface Coordinates

Abstract interface for coordinates. This interface defines the common methods for all image coordinate systems used.

Method Summary

double	dist(Coordinates pos) Return the distance between this position and the given one in the standard units of the coordinate system being used (arcmin for WorldCoords, pixels for ImageCoords, ...).
java.lang.String	getCoordinateSystemName() Returns the name of the coordinate system as a string.
double	getX() return the X coordinate as a double
double	getY() return the Y coordinate as a double
java.lang.String	toString() Return the coordinates as a string.

Method Detail

getCoordinateSystemName

dist

double dist(Coordinates pos)

Return the distance between this position and the given one in the standard units of the coordinate system being used (arcmin for WorldCoords, pixels for ImageCoords, ...).

Parameters:

pos - The other point.

Returns:

The distance to the given point.

getX

double getX()

return the X coordinate as a double

getY
