An encapsulation of a font; i.e. a set of glyphs that may be assembled together by a TextNode to represent a string of text.

|
const TextGlyph | getGlyph (int character) |
| Gets the glyph associated with the given character code, as well as an optional scaling parameter that should be applied to the glyph's geometry and advance parameters. Returns the glyph on success. On failure, it may still return a printable glyph, or it may return NULL. More...
|
|
float | getLineHeight () |
| Returns the number of units high each line of text is. More...
|
|
float | getSpaceAdvance () |
| Returns the number of units wide a space is. More...
|
|
bool | isValid () |
| Returns true if the font is valid and ready to use, false otherwise. More...
|
|
TextFont | makeCopy () |
|
| setLineHeight (float line_height) |
| Changes the number of units high each line of text is. More...
|
|
| setSpaceAdvance (float space_advance) |
| Changes the number of units wide a space is. More...

|
| write (Ostream out, int indent_level) |

Public Member Functions inherited from TypedObject |
TypeHandle | getType () |
| Derived classes should override this function to return get_class_type(). More...
|
|
int | getTypeIndex () |
| Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More...
|
|
bool | isExactType (TypeHandle handle) |
| Returns true if the current object is the indicated type exactly. More...
|
|
bool | isOfType (TypeHandle handle) |
| Returns true if the current object is or derives from the indicated type. More...
|
|
Public Member Functions inherited from ReferenceCount |
int | getRefCount () |
| Returns the current reference count. More...
|
|
| ref () |
| Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More...
|
|
bool | testRefCountIntegrity () |
| Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | testRefCountNonzero () |
| Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | unref () |
| Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...
|
|
Public Member Functions inherited from Namable |
| __init__ (const Namable copy) |
|
| __init__ (str initial_name) |
|
| clearName () |
| Resets the Namable's name to empty. More...
|
|
str | getName () |
|
bool | hasName () |
| Returns true if the Namable has a nonempty name set, false if the name is empty. More...
|
|
Namable | operator= (const Namable other) |
|
| output (Ostream out) |
| Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this. More...
|
|
| setName (str name) |
