[mapserver-users] Truetype font rendering changes?

[Lime, Steve D (DNR)]

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?

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.

Is that test case available someplace?

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.

Johan,

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

Regards,

Donald

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!
