[mapserver-users] Square Edges Using labelpoly

[Lime, Steve D (MNIT)]

It's an issue with 6.4, I don't have a 7.0 build handy. I'll try it and see. Thomas refactored a bunch of the labeling code in 7.0 so maybe it's not an issue.

The two styles suggestion worked. Thank you both for your help!

Steve,

Do you know if this is still an issue with the current release of mapserver? I am running 6.0.3 so I am curious to know if this issue still exists. If so, would you like me to raise a ticket for this?

Regards,

Zach

Seems to be the combination of the fill and the outline that forces the rounded outline. Here's a test:

  1) Outline, LINEJOIN MITER, LINECAP SQUARE: http://maps1.dnr.state.mn.us/cgi-bin/mapserv64?map=/usr/local/mapserver/apps/test/labelpoly/test1.map&mode=map
  2) Fill and outline, LINEJOIN MITER, LINECAP SQUARE: http://maps1.dnr.state.mn.us/cgi-bin/mapserv64?map=/usr/local/mapserver/apps/test/labelpoly/test2.map&mode=map

Besides seemingly not respecting the LINEJOIN/LINECAP values, the label polygon doesn't include the baseline decent of the lower case y. Hmmm...

Sure seems like a bug...

However, you can work around it. Just use two styles. One to draw the outline and one to fill... (see mapfile below)

  3) Two styles, outline uses LINEJOIN MITER, LINECAP SQUARE: http://maps1.dnr.state.mn.us/cgi-bin/mapserv64?map=/usr/local/mapserver/apps/test/labelpoly/test3.map&mode=map

Håvard,

Thanks for your help. Unfortunately, the polygon did not change when specifying "LINEJOIN miter" (see below) and still has curved edges. Any other ideas?
        STYLE
          ANGLE 0
          COLOR 149 149 149
          GEOMTRANSFORM "labelpoly"
          OFFSET 0 0
          OUTLINECOLOR 149 149 149
          WIDTH 22
          LINEJOIN miter
        END # STYLE

Regards,

Zach

LINEJOIN miter
in the STYLE element should work also for labelpoly see http://mapserver.org/mapfile/style.html

LABEL
   STYLE
     GEOMTRANSFORM labelpoly
     OUTLINECOLOR 255 0 0
     WIDTH 4
     LINEJOIN miter
   END # Style
...
END # Label
