Jan 2007: I. Morozov - it seems that in GMT version 4, the position of the color bar is specified by the lower-left corner of the plot, and not by its center. Changes made to preserve the old convention.

Module description:

GMT interface

An interface for GMT (Generic Mapping Tools) programs. GMT allows plotting plots and geographic maps in a variety of projections.

GMT accepts images built by preceding calls to IMAGE, converts them to PpstScript, and optionally displays the resulting file by calling a PostScript viewer.

Wherever possible, the commands are identical to those used by tool PLOTMTV.

GMT performs all operations during the EOF phase.
