use system fonts to export pdf without copy them in font extension

[thierry_gesteam]

Hi,

Using font extension (to export pdf)  involve adding jar containing fonts in the application.

This one become big with few fonts.

If systems running application using jasper have already the fonts, this is a crazzy duplicates !

On Windows, system have "standard" fonts (all machine have them)

So, is there a way to use directly these system fonts without copy them in font extension ?

in iReport ?

in jasper application ?

(jasperreport 4.0.2, windows XP, 7... )

Thanks a lot

Hi,

Actually, the fonts themselves are not required as part of the font extension jar. But you have to properly set the path to the font files existing on the Windows machine in the font extension xml file.

Thanks sanda,

 

I suppose i can't use system variable in the path. But the font folder path is not constant on all systems.

So, it seem impossible to distribute an application using system font without coping them in the jar. :-(

Hi,

This portability requirement was the reason font extensions were introduced for.
In the case you need dynamic path definitions try to consider a dynamic font extension approach.

First, create a CustomFontExtensionsRegistry class (which implements net.sf.jasperreports.extensions.ExtensionsRegistry) with a customized getExtensions() method. There you can instantiate and load all your needed FontFamily objects using system path variables.
Second, create a CustomFontExtensionsRegistryFactory class (which implements net.sf.jasperreports.extensions.ExtensionsRegistryFactory) to instantiate a CustomFontExtensionsRegistry object.
Third, in the jasperreports_extension.properties file set the custom registry factory class:

net.sf.jasperreports.extension.registry.factory.custom.font.families=<your_package_here>.CustomFontExtensionsRegistryFactory

Finally, make sure your custom classes are in the app classpath.

Hope this helps,
