[mapserver-users] Legend size problem in GetLegendGraphic request

[Lime, Steve D (DNR)]

We could always size symbols relative to the KEYSIZE but if you do that then relative differences between wide and narrow lines or large and small markers would be lost. If units are in pixels then one could compute a global scaling factor across all layers so that differences are preserved. Doesn't help with non-pixel units.

Thx Steve,

Shouldn't the request somehow take into account the KEYSIZE, that is always in pixels?

Anyway, I have reported this (before your email) as a bug: http://trac.osgeo.org/mapserver/ticket/4177

In the mean time, yes I could use KEYIMAGE, I just wanted to avoid it. Or I can make my points circles and use pixels for SIZEUNITS
