[mapserver-users] OGR - ArcInfo Coverage Help

[Lowell Filak]

Currently the routine in the wiki only reads in the first and last definition point for the text and creates a two-point line based on that. It can definitely be modified to read in all the points but currently would not be rendered using all of them. By using a truetype font and angle auto the text should follow the line.
