[mapserver-users] Legend difference in 5.6.1 and 6.4.1 (mapserver)

[Weisbender, Eric]

Hello List,

With my legend font I am having the exact same problem on the exact same version of MapServer.  In the mean time I have reverted back to BITMAP font but would like to continue using TRUETYPE.  I have also tried multiple variation of Legend definition and am currently copying my old .ttf files from our previous server.  Any insight to this issue is greatly appreciated.

Thanks,

Eric Weisbender

J?rg,

looks like this is a minefield :(

Strange enough, using bitmap fonts the class names don't get truncated, but then I don't have the beloved German umlauts. This sure enough looks like a miscalculation of the space the average letter of a proportional font needs and so the space allocated for the class name is too small.

Don't know why it worked in 5.6.1 but broke in the transition to 6.4.1
