yes, but I would like to display special symbols (for cadastral maps), not only
circles... I don't understand relation between BOX (larger side) and symbol
scaling (in map units). So I am not sure if it is possible to find relation
between size of symbols and map units...


BTW, how to display part of circle (ARC) (90deg->270deg clockwise).

    ARC 0.25 0.75 0.75 90 270 works

    I need ARC 0.25 0.75 0.75 90 270 C (or ARC 0.25 0.75 0.75 270 90) -> I get only line...

Thanks,
	
Martin
