Flavio,

Thanks for the example!

As I wrote to Daniel (I replied to him, instead of the list, sorry):This works, sometimes. I know get this nice error:


msDrawMap(): Image handling error. Failed to draw layer named 'topo'.
msOGRGetValues(): OGR error. Invalid field index!?!

For *some* layers. Others do seem to work...

Any ideas?

Example, if those are MapInfo Text Features (see LABELITEM and
LABELANGLEITEM):

LAYER
  NAME "Streets fro Labeling"
  TYPE ANNOTATION
  MINSCALE 0
  MAXSCALE 300
  SYMBOLSCALE 2000
  STATUS ON
  CONNECTIONTYPE OGR
  CONNECTION "..\data\streets.TAB"
  LABELITEM "OGR:LabelText"
  LABELANGLEITEM "OGR:LabelAngle"
    CLASS
      NAME "Street Labels"
      COLOR -1 -1 -1
      LABEL
        ANTIALIAS TRUE
        TYPE TRUETYPE
        FONT arial
        MINSIZE 1
        SIZE 2
        COLOR 0 0 0
      END
    END
END

Mit freundlichem Gruss / Best Regards
Flavio Hendry

Subject: [UMN_MAPSERVER-USERS] Question about Labels

Hello everyone,

It's been quite a while since I posted here, everything went pretty
smooth so far.

Now I have a small problem with labels. We have MapInfo .TAB files,
which are converted from AutoCAD drawings (meaning everything is in
one
layer).
When I open one of these files in MapInfo, I can see labels on some
places. When I draw the map with MapServer, I see only the
(poly)lines.

So, I added an extra layer of type Annotation. This, by default,
doesn't
show me any layers. So I need to add LABELITEM, but I have no idea
what
layers need to be labeled. Also, this changes with every file that's
being drawn.

Does anyone know how to tell MapServer to draw labels "The MapInfo"
way?


My current layer definition:


LAYER
        NAME topo
        MINSCALE 1
        MAXSCALE 3000
        STATUS ON
        Type LINE
        CONNECTIONTYPE OGR
        CONNECTION "e:\topo.tab"
        STYLEITEM "AUTO"
        Class
        End #CLASS
End #LAYER
LAYER
        NAME topo
        MINSCALE 1
        MAXSCALE 3000
        LABELMAXSCALE 50000
        STATUS ON
        Type ANNOTATION
        CONNECTIONTYPE OGR
        CONNECTION "e:\topo.tab"
        CLASS
                LABEL
                        COLOR 100 0 0
                        POSITION LR
                        SIZE MEDIUM
                END #label
        END #CLASS
End #LAYER

Any help would be greatly appreciated!

With kind regards,
