Glynn: > What's wrong with r, d and c? see examples in above URL. (but wait 'til tomorrow; right now the server's down due to electrical work in the building) IIRC r and d's method of drawing polylines gives fuzzy results. > g should only be used if none of the others can be made to work. IIRC c is very close, AFAICT it is just the two white lines at the edges of the map which are a problem. > To get rid of the problem with render=l drawing beyond the edge of the > region, d.vect needs to set the raster clip window (R_set_window()) to > match the region (D_setup() sets it to match the frame), but it needs > to be set back afterwards (D_setup(0) should suffice). Does that cure the incorrect polygon filling too? (1/2 way down in above URL) Is 'l' the absolute favorite, or is it a case of choosing the best compromise from several near equals? In the quality vs. time tradeoff we must have minimum standards for both variables. I wouldn't mind the other methods if the above issues could be fixed. Right now I think they fail the minimum quality test. > Also: > > 1. d.vect uses the same rendering mode for both fills and strokes, > which isn't necessarily desirable. > > 2.

In what cases would you want clipped to be anything other than a full mask? displaying a solid boundary line when there is not one there is dangerous.
