Anti Alias Problem

[Thomas Hammerlund]

Thank you for your reply Steve.

I'm running mapserver 4.8.3 and outputting jpegs via the gdal/jpeg driver.
I'm using the gdal driver because the gd/jpeg driver output progressive
encoded jpegs(which i couldn't use).

Example layer:
LAYER
  NAME l_koku_u
  STATUS ON
  TILEINDEX "ixs/shb/50000/l_koku_u_ix"
  TILEITEM "location"
  TYPE LINE
  CLASSITEM Code
CLASS
 MAXSCALE 337000
 MINSCALE 85001
 Name style1
 EXPRESSION 'l_bbbcd'
    STYLE
      COLOR 240 184 53
      WIDTH 1
           #ANTIALIAS TRUE
    END
  END
END

I'm creating my image using perl mapscript.  my mistake, the problem is not
with the fonts but with the lines.  when I turn style antialiasing on for my
line layers perl throws an internal server error with no error message from
mapserver (or perl).

The outputformat in my mapfile looks like this:

OUTPUTFORMAT
NAME jpeg
DRIVER "GDAL/JPEG"
MIMETYPE "image/jpeg"
 IMAGEMODE RGB
FORMATOPTION "QUALITY=100"
 EXTENSION "jpg"
END

Which antialias patch are you referring to?

Thank you again,
Tom
