[mapserver-users] Truetype font rendering changes?

[Stephen Woodbridge]

Johan,

You need to provide a simple test case if you want a developer to help 
diagnose this problem.

I would suggest creating a simple mapfile that draws a single label like 
the following. Adjust it to your needs

MAP
   SIZE 100 100
   EXTENT 100 100
   UNITS inches
   FONTSET "fontset.txt"
   IMAGETYPE ...

   OUTPUTFORMAT
     ...
   END

   LAYER
     TYPE POINT
     STATUS DEFAULT
     FEATURE
       POINTS 50 50 END
     END
     CLASS
       STYLE
         SYMBOL 0
         COLOR 0 0 0
       END
       TEXT "123"
       LABEL
         TYPE TRUETYPE
         FONT "arial-narrow"
         SIZE 7
         COLOR 0 0 0
       END
     END
   END
END

Test this on both servers. Also make sure you are using the same font 
file, ie copy it to your test example directory and create a new 
fontset.txt that only have this single font referenced in it. If you 
still get different results, then tar/zip up the test example and email 
it to Steve L or me and I will make it available as a link if you can 
post a link to it.

I have also created a test case using MS6 on the same Linux server (but outside the FGS95 environment) as my MS5.4 and the text is rendered exactly the same as on the Windows platform, with the same reduced legibility.

Most things are migrating well however I have a peculiar TrueType font rendering issue where the readability on the new system is far less than on the old system. I have attached two screenshots taken at the same scale to illustrate the issue. In these images the parish labels are Arial Bold Italic 6 pt., the interstate shields are Arial 8 pt., and US highway shields are Arial Narrow 7 pt. The TTF files and the MAP files were copied directly from the old system to the new system. I have tried with antialias on and off in the label definition and with a couple of different AGG image output formats but there are no visible differences.
