[mapserver-users] OGR - ArcInfo Coverage Help

[Matthew Archer]

Hi,

Converting to lines works for some texts, however:

How do i get the text to follow the line?

Unfortunately, converting to lines does not work well for 3+ point lines 
(ie curved text) and multi-row text where each row is set specifically 
(wordposition in ArcInfo).
