I have a problem with the left polygon on the image at http://www.jgrass.org/cgi-bin/moin.cgi/HowItIsGoingWithVisad?action=show but I believe it is a winding rule problem somewhere. It draws the polygon outside the shape instead of inside. I see in the mailinglist archives that it is only possible to create a buffered image of the size of the screen throught the getImage method. Is that true? No way to create custom ones that take into consideration the current resolution of the visualized data?
