Fonts
The Fonts collection contains Font objects representing fonts used to display text features. Access to collection items is possible both by name and by internal number. An internal number is generated when a font is added to the library. Continuity of font numbers is not guaranteed. Persistence of the font internal number is guaranteed until its reorganization that is performed by the GDBEngine::CompactSharedLibrary method with the mode == gdbCompactNoKeepISN.
