[udig-devel] What glyph is this? Hi Moovida

[Jody Garnett]

You can have any size you want ... the layer view scales things down to 
16x16 (or else the SWT widget starts to look stupid). The legend map 
graphic ... well I imagine we can make it do whatever you want (but I 
recommend scaling things to similar width - some WMS servers have very 
odd ideas about what would make a good graphic).

Cheers,
Jody
