[mapserver-users] Square Edges Using labelpoly

[Lime, Steve D (MNIT)]

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
