Truetype font rendering changes?

Johan Forsman
Hello All:

I am in the process of migrating from MapServer 5.4 (FGS95 on Linux) to MapServer 6 (MS4W3 on Windows Server 2008 R2). 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.

I would really appreciate any suggestions or pointers where to investigate.

Thanks!

Johan,

Have you tried "cairopng" as an alternative to AGG?

Regards,

Donald

Thank you for the suggestion however I regret to report that there is no discernible difference in the appearance of the text when using cairopng in the Windows environment. 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.

Thanks,
Johan.

RE: Truetype font rendering changes?

Johan Forsman
No. Unfortunately none of the sites are accessible from the outside. The best I can do are screenshots.

I attached two examples from the same Linux server. One is from the FGS95 (MS54) environment and the other (MS60) is under the "main" system environment. Both samples are of Arial Narrow 7 point, and the image is rendered using the following output format:

OUTPUTFORMAT
    NAME 'agg_q'
    DRIVER AGG/PNG
    IMAGEMODE RGB
    FORMATOPTION "QUANTIZE_FORCE=ON"
    FORMATOPTION "QUANTIZE_DITHER=OFF"
    FORMATOPTION "QUANTIZE_COLORS=256"
END

I freely confess to not knowing much about the various output formats. This one I picked from the list some time long ago. I tried other formats also, both 8- and 24-bit and both the AGG and Cairo drivers, but I have not noticed any clear differences.

Thanks for any suggestions and I'll be glad to collect additional information if needed.

Johan.

It looks like the effective size of the text has changed. What happens if you play with the font size in 6.0 and increase it a bit?

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.

Hello Johan,

I have created bug #4308
https://github.com/mapserver/mapserver/issues/4308
and put a link to your tar file on my server.

Thank you for taking the time to create a simple test case, I'm sure
this will accelerate getting it resolved.
