Where can I find a map from font font face names to filenames?

Question

I'm trying to write a Java program that finds the TTF for a font face given its name. For example, inputting "Times New Roman" on my Windows machine would return the path "C:\Windows\Fonts\times.ttf".

Most other font face names are abbreviated in a similar manner in the name of their TTF file. Is there a standard somewhere that I can use to map font face names to corresponding TTF filenames predictably?

Answer 1

Remember that the name of the font is defined within the contents of the font file, so there's no reason there should be any relation with the name of the font file itself.

In Windows XP the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts lists all the permanent installed system fonts. You can enumerate this list of font files, opening each one in turn and if it is a ttf you can get the checkSumAdjustment from its head table. Build a list of items, each item containing a pair of values - the font file name and the checksum value.

Then when you later realize a font, call GetFontData on it and read the head table and find the checkSumAdjustment for that font. Then look it up in the list you made earlier.
