## com.bbn.openmap.proj
Interface EqualArc

All Superinterfaces:
  Projection, java.io.Serializable

All Known Implementing Classes:
  CADRG, LLXY

public interface EqualArc
extends Projection

A designator interface to let layers know that a Projection is an Equal Arc projection, meaning that the variations in latitide and longitude are constant.

Method Summary
`double` `getXPixConstant()` Returns the x pixel constant of the projection.
`double` `getYPixConstant()` Returns the y pixel constant of the projection.

Method Detail

### getXPixConstant

    public double getXPixConstant()

  Returns the x pixel constant of the projection. This was calcuated when the projection was created. Represents the number of pixels around the earth (360 degrees).

### getYPixConstant

    public double getYPixConstant()

  Returns the y pixel constant of the projection. This was calcuated when the projection was created. Represents the number of pixels from 0 to 90 degrees.
