A rounded rectangle is drawn as a border. If the image does not exist, the card is constructed as follows. 2) a white pixmap of full cardsize is created. The width and height are taken from the Cards.conf file (1st line) and default to 79x123. 3) The default card background, taken from Background.xpm, is centered in the pixmap. 4) Rank and small suit symbols are drawn into the pixmap. 5) If a center picture does exist (filename "(rank).(suit).pic.xpm"), it is centered in the card. Otherwise, the card is filled with suit symbols. 6) A rounded rectangle is drawn as card border. For pictures (Jack to King), the procedure in 5) is slightly different, as the center pictures have to be mirrored and drawn twice. The cards may be configured by the Cards.conf file. This file is optional and may end after any line.
