FontPool¶

from acron.core import FontPool

class FontPool¶

Bases:

This is the preferred interface for loading fonts for the TextNode system. It is similar to ModelPool and TexturePool in that it unifies references to the same filename.

static add_font()¶: 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.

static garbage_collect()¶: 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.

static has_font()¶: Returns true if the font has ever been loaded, false otherwise.

static list_contents()¶: Lists the contents of the font pool to the indicated output stream.

static load_font()¶: 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.

static release_all_fonts()¶: Releases all fonts in the pool and restores the pool to the empty state.

static release_font()¶: 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 ever loaded, and fonts will never be freed.

static verify_font()¶: 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.

static write()¶: Lists the contents of the font pool to the indicated output stream.
