Polyline annotation line thickness

iznally — Sun, 02 Dec 2012 12:17:26 GMT

Hi all,

I'm stucked with the line thickness of polylines (annotate functions polyline and polycont). There seem to be just the choice between extremely thin (size=1) and thick (size=2). Using decimal values doesn't return an error, but has no effect either. As per the online documentation these are pixel values and the unit cannot be changed. But the line with size 2 is definitely more than two pixels thick...?

I'm using this function to accentuate particular state borders on my map.

Thanks in advance for any advice!

I usually go with lighter & darker colors for the 2 borders, rather than thin/thicker lines.

Here's an example from my book:

Thanks Robert! Yes thats a possibility, but I would really like to keep them in the same color - there's no option for a more differentiated size setting?

We can adjust thin/thickness of the polygon annotation or polyline annotation when we call and program the annotation creating component by adjusting the methods of ”fill As AnnotationBrush, shadow As AnnotationBrush, shadowX As Single, shadowY As Single“. By the way, annotation line or shadow color also are adjustable.
