DESCRIPTION

This script converts a chess-position in FEN syntax into an image in .jpg or .png or .eps format.

It incorporates the same code as makes up the chess.ps PostScript library,
and feeds the result into gs to convert into .jpg or .png format.

OPTIONS

-f

The board will be displayed Flipped, ie: from Black's point of view.

-w 700

This option sets the Width in pixels of the .jpg or .png image, or the width in points of .eps files. Widths less than about 400 may produce unsightly moire effects on the dark squares. The default width is 450

-v

Prints the Version
