fi.luomus.commons.utils.CoordinateConverter
Converts coordinates between EUREF-FIN (ETRS-TM35FIN), Uniform (KKJ yhtenäiskoordinaatisto), natural degrees (KKJ astekoordinaatisto) and decimal coordinates (KKJ desimaalikoordinaastio). Conversion is done by calling convert() method. Before that, one type of coordinates must be set. If no source coordinates are set, an IllegalArgumentException is thrown.
jsky.coords.CoordinateConverter
This interface may be implemented by classes that display images and can convert between different coordinate systems, optionally including world coordinates. Methods are available for converting between the following coordinate systems:

Screen Coordinates

The origin (0,0) is always at the upper left corner of the window. Whole pixels are counted and no transformations are taken into account.

Canvas Coordinates

The origin (0,0) is at the upper left corner of the image. Whole pixels are counted and no transformations are taken into account.

Image Coordinates

The origin is at lower left (FITS style) after all transformations are undone. At mag 1, the origin is (1, 1), otherwise it is a fraction of a pixel (0.5, 0.5). Image coordinates correspond to the coordinates in a FITS image.

User Coordinates

The origin (0.0, 0.0) is at upper left after all transformations undone. User coordinates are like image coordinates, except that the Y axis is reversed and the origin at mag 1 is (0., 0.) instead of (1. 1).

World Coordinates

World coordinates are converted from image coordinates based on the keywords in the image header, if available.
