问题
I have some ttf fonts installed on system.
I get that list using
GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames()
This is not only ttf fonts but all fonts I guess. Eventually if I use:
Font.decode(fontName)
I can get awt.Font instance.
As far as I know Font is not connected to actual PhysicalFont, so how can I retrieve either ttf font file, or byte data from that ttf file for a font from that list or from awt.Font ? I am trying to retrieve a physical font data or anything similar. That data should be somewhere right?
The reason I need it is to eventually use with libGDX FreeTypeFontGenerator in order to generate BitmapFont
This has to work on windows, osx and linux.
回答1:
It isn't possible. The best you can do is using reflection, but it will only work with an Oracle JRE and accesses a private API so may break with any new Oracle release.
You could probably write a native lib to enumerate the fonts and their files.

As @NateS pointed out, it appears what I want to achieve is not exactly possible.
So I will just share the solution I used in my case for now:
Which is this class: FontManager.java
This allows to pre-cache existing ttf files in known system locations based on your system, and then make a Map for fontName->fontFile type of connection. this then goes to preferences, and is loaded on next run.
Known issues are
- awt.Font has a known bug that is not able to read some ttf font family names on osx systems (mainly some arabic and chinese fonts)
- Did not test on Linux, will probably fail.
- First run might be slow if you have many fonts.
It would be ideal to write a native lib, but time is of an essence...
