Methods of FreetypeFont:

Methods of Namable:

getFontPixelSize
int FreetypeFont::get_font_pixel_size(void) const;

Description: This is used to report whether the requested pixel size is being only approximated by a fixed-pixel-size font. This returns 0 in the normal case, in which a scalable font is used, or the fixed-pixel-size font has exactly the requested pixel size.
If this returns non-zero, it is the pixel size of the font that we are using to approximate our desired size.

getLineHeight
float FreetypeFont::get_line_height(void) const;

Description: Returns the number of units high each line of text is.

getNativeAntialias
bool FreetypeFont::get_native_antialias(void) const;

Description: Returns whether Freetype's built-in antialias mode is enabled. See set_native_antialias().

getPixelSize
float FreetypeFont::get_pixel_size(void) const;

Description: Returns the size of the font in pixels, as it appears in the texture.

getPixelsPerUnit
float FreetypeFont::get_pixels_per_unit(void) const;

Description: Returns the resolution of the texture map. See set_pixels_per_unit().

getPointSize
float FreetypeFont::get_point_size(void) const;

Description: Returns the point size of the font.

getPointsPerInch
static float FreetypeFont::get_points_per_inch(void);

Description: Returns the number of points in one inch. This is a universal typographic convention.

getPointsPerUnit
static float FreetypeFont::get_points_per_unit(void);

Description: Returns the point size of the font that is one Panda unit high. This is an arbitrary Panda convention for text, and is set to 10.0.

getScaleFactor
float FreetypeFont::get_scale_factor(void) const;

Description: Returns the antialiasing scale factor. See set_scale_factor().

getSpaceAdvance
float FreetypeFont::get_space_advance(void) const;

Description: Returns the number of units wide a space is.

setNativeAntialias
void FreetypeFont::set_native_antialias(bool native_antialias);

Description: Sets whether the Freetype library's built-in antialias mode is enabled. There are two unrelated ways to achieve antialiasing: with Freetype's native antialias mode, and with the use of a scale_factor greater than one. By default, both modes are enabled.
At low resolutions, some fonts may do better with one mode or the other. In general, Freetype's native antialiasing will produce less blurry results, but may introduce more artifacts.

setPixelSize
bool FreetypeFont::set_pixel_size(float pixel_size);

Description: Computes the appropriate pixels_per_unit value to set the size of the font in the texture to the indicated number of pixels. This is just another way to specify pixels_per_unit().

setPixelsPerUnit
bool FreetypeFont::set_pixels_per_unit(float pixels_per_unit);

Description: Set the resolution of the texture map, and hence the clarity of the resulting font. This sets the number of pixels in the texture map that are used for each onscreen unit.
Setting this number larger results in an easier to read font, but at the cost of more texture memory.
This should only be called before any characters have been requested out of the font, or immediately after calling clear().

setPointSize
bool FreetypeFont::set_point_size(float point_size);

Description: Sets the point size of the font. This controls the apparent size of the font onscreen. By convention, a 10 point font is about 1 screen unit high.
This should only be called before any characters have been requested out of the font, or immediately after calling clear().

setScaleFactor
bool FreetypeFont::set_scale_factor(float scale_factor);

Description: Sets the factor by which the font is rendered larger by the FreeType library before being filtered down to its actual size in the texture as specified by set_pixels_per_unit(). This may be set to a number larger than 1.0 to improve the font's antialiasing (since FreeType doesn't really do a swell job of antialiasing by itself). There is some performance implication for setting this different than 1.0.
This should only be called before any characters have been requested out of the font, or immediately after calling clear().

clearName
void Namable::clear_name(void);

Description: Resets the Namable's name to empty.

getClassType
static TypeHandle Namable::get_class_type(void);

Undocumented function.

getName
string const &Namable::get_name(void) const;

Description:

hasName
bool Namable::has_name(void) const;

Description: Returns true if the Namable has a nonempty name set, false if the name is empty.

operator =
Namable &Namable::operator =(Namable const &other);

Description:

output
void Namable::output(ostream &out) const;

In the absence of any definition to the contrary, outputting a Namable will write out its name.
Description: Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

setName
void Namable::set_name(string const &name);

Description:
