[MapServer-users] Looking for Examples of COMPOSITE

[Lars Schylberg]

Hi Bob,

I have an example how to use COMPOSITE and blur effects on a line and 
other objects that I presented at FOSS4G last year in Italy.

https://github.com/LarsSchy/FOSS4G-2022/blob/main/layer_comp2.map.

The example can be run with map2img.

The presentation is here:

Have fun / Lars Schylberg

You could also add transparency to your outline color. > > > On 8/3/23
