Truetype Font Wrapping Patch

[Bart van den Eijnden]

Hi,

can you open up a bugzilla report in the Mapserver bugzilla so this does not get lost?

Thanks.

Best regards,
Bart

Hi,

We've been using Minnesota Map Server in a live WMS service for a few
months now and we have found it to be an excellent piece of software. We
have found what seems to be a small problem though. We tried using the
WRAP command inside of LAYER to specify that a text string should wrap
to the next line when it encounters a certain symbol but for some reason
we couldn't get this to work when using truetype fonts. I had a look a
the code and it seems that the line wrapping code in the bitmap font
section wasn't in the truetype font code in mapgd.c. When I added the
code into the truetype font section, then the line wrapping command
worked fine. I've attached a patch of the fix for version 4.6.0.

This is the relevant section of the mapfile:

LAYER

    METADATA
        "wms_title" "Copyright"
        "wms_srs"   "EPSG:27700"
        "wms_extent"    "0.0 0.0 700000.0 1300000.0"
    END

    END

    END

END # End copyright
