Constructor & Destructor Documentation
◆ FontManager()
| FontManager::FontManager | ( | void * | free_type_library = NULL | ) |
Constructor: uses the given FT_Library handle otherwise will initialize and use its own FT_Library.
Definition at line 42 of file FontManager.cpp.
References vl::Log::error(), mFreeTypeLibrary, NULL, and VL_TRAP.
◆ ~FontManager()
| FontManager::~FontManager | ( | ) |
Destructor: releases all fonts and disposes the FT_Library if not NULL.
If you don't want the FontManager to dispose the associated FT_Library then call setFreeTypeLibrary(NULL) before the FontManager is destroyed.
Definition at line 58 of file FontManager.cpp.
References mFreeTypeLibrary, NULL, and releaseAllFonts().
