I want to convert some Mapinfo styles to Mapserver.
Here, I found some examples on how to make symbols. But I don't understand how it works.

For example a dashed line:

 NAME "mapinfo-pen-73"
 TYPE vector
 FILLED true
  5 25
  25 30
  45 30
  35 25
END # Points

And i get my dashed line.

What does the POINTS block mean? I can't find any explanation, how to write POINTS by self. Where i can find documentation?


After i'd readed @user30184 and @Andreas answers i'm steal dont understand POINTS block.

I'm looking on my example in map:

enter image description here

i see dashed line.
If POINTS it is a polygons shape it's look like:

enter image description here

This moment dont clear for me. Why shape form different with dashed like form?

Im missed with Y axe. But anyway shape form very strange.

    Points means Shape here. The given coordinate pairs (Points) form a shaped area, which represents the symbol. Inside a map layer you can then use this symble and color it, size it or whatever by binding it to an feature/attribute. Mar 12, 2018 at 14:49
  • I think that this description is quite good: mapplus.ch/neapoljs-dojo/v2.5.2/wmcm/help/MapServer/… The tricky part is that the symbol coordinate system is upside down.

How to construct symbols for MapServer is explained in the document that you have been reading. http://www.mapserver.org/mapfile/symbology/construction.html.

How to use POINTS is written rather unclearly

For symbols of TYPE vector and ellipse the shape of the symbol by setting X and Y values in a local two dimensional coordinate system with X values increasing to the right and Y values increasing downwards. The coordinates defining the symbol is listed in the POINTS parameter, which is explicitly ended using END. Negative values should not be used.

Example should clarify the usage. Let's make an unfilled triangle symbol with corners at coordinates (0 0), (2 0), and (2 1).

enter image description here

  NAME "triangle"
  TYPE vector
    0 0
    2 0
    2 1
    0 0
