Hi Jörg,
I've been playing around with the MINSCALE etc. When using an OUTLINECOLOR you
also need to set the MINWIDTH and MAXWIDTH on the SYMBOL to change sizes with
resolution. I think this is the issue you were seeing in your example.
For example to keep a constant outline width of 1 you can use the following:
STYLE
SYMBOL "circle"
SIZE 100
MAXSIZE 200
MINSIZE 12
COLOR "#F9A03F"
OUTLINECOLOR "#813405"
MINWIDTH 1
MAXWIDTH 1
END
There is a working example at https://app.mapserverstudio.net/#akyRvQvW - if
you zoom in you will notice the circles get bigger (up to 200 pixels) but the
outline width remains at 1 pixel.
