addFont static void FontPool::add_font(string const &filename, TextFont *font); Description: Adds the indicated already-loaded font to the pool. The font will always replace any previously-loaded font in the pool that had the same filename. |
garbageCollect static int FontPool::garbage_collect(void); Description: Releases only those fonts in the pool that have a reference count of exactly 1; i.e. only those fonts that are not being used outside of the pool. Returns the number of fonts released. |
hasFont static bool FontPool::has_font(string const &filename); These functions take string parameters instead of Filenames because that's somewhat more convenient to the scripting language. Filename: fontPool.I Created by: drose (31Jan03) PANDA 3D SOFTWARE Copyright (c) Carnegie Mellon University. All rights reserved. All use of this software is subject to the terms of the revised BSD license. You should have received a copy of this license along with this source code in a file named "LICENSE." Description: Returns true if the font has ever been loaded, false otherwise. |
listContents static void FontPool::list_contents(ostream &out); Description: Lists the contents of the font pool to the indicated output stream. |
loadFont static TextFont *FontPool::load_font(string const &filename); Description: Loads the given filename up into a font, if it has not already been loaded, and returns the new font. If a font with the same filename was previously loaded, returns that one instead. If the font file cannot be found, returns NULL. |
releaseAllFonts static void FontPool::release_all_fonts(void); Description: Releases all fonts in the pool and restores the pool to the empty state. |
releaseFont static void FontPool::release_font(string const &filename); Description: Removes the indicated font from the pool, indicating it will never be loaded again; the font may then be freed. If this function is never called, a reference count will be maintained on every font every loaded, and fonts will never be freed. |
verifyFont static bool FontPool::verify_font(string const &filename); These functions take string parameters instead of Filenames because that's somewhat more convenient to the scripting language. Description: Loads the given filename up into a font, if it has not already been loaded, and returns true to indicate success, or false to indicate failure. If this returns true, it is guaranteed that a subsequent call to load_font() with the same font name will return a valid Font pointer. |
write static void FontPool::write(ostream &out); Description: Lists the contents of the font pool to the indicated output stream. |
