Font size differs on Windows and Linux machines

Eugene Podshivalov
Hi all,
I had a style created in Windows envrionment and then copied the file to Linux server.
Although the style file is identical on both machines the labels on WMS tiles on Linux are rendered bigger than on Windows.

It is SansSerif font-family.

Does anyone know the reason?

Regards,
Eugene

Re: Font size differs on Windows and Linux machines

Hi,
I might be wrong, but believe that "Sans Serif" is not an actual specific font, but just a name that 
is best matched to whatever sans serif font is available. From the Java documentation:

-------------

Java SE defines the following five logical font families:

  • Dialog
  • DialogInput
  • Monospaced
  • Serif
  • SansSerif
These fonts are available on any Java platform and can be thought of as aliases for some underlying font that has the properties implied by its name. A Serif font is a font similar to Times New Roman, which is commonly used in print. A Sans Serif font is more typical for onscreen use.

These fonts can be customized for the locale of the user. In addition these fonts support the widest range of code points (Unicode characters).

-------------

I would use the same physical font instead (there are a lot out there that are open source and can be freely installed across platforms), e.g. Google's Noto or Vera Sans.

If that's not the (only) issue, there might also be platform specific differences, for example I believe OpenJDK on Linux uses whatever FreeType library version is available on system, while Oracle JDK on Windows might be using a different library (unsure, you might want to check).

Cheers
Andrea

Re: Font size differs on Windows and Linux machines

Hi Andrea,
Both environments have Oracle JRE installed. I've just compared the font previews in the Geoserver web interface and they do differ
The first group is from Windows and the second one is from Linux

So most likely you are right thinking that JVM is using system fonts, rather than the default Java fonts.

Thanks,
Eugene
