A typeface represents a size-independent font.
This base class is abstract, but calling createSystemTypefaceFor() will return a platform-specific subclass that can be used.
The CustomTypeface subclass allow you to build your own typeface, and to load and save it in the Juce typeface format.
Normally you should never need to deal directly with Typeface objects - the Font class does everything you typically need for rendering text.

Creates a new system typeface.

|
virtual |
Returns true if this typeface can be used to render the specified font.
When called, the font will already have been checked to make sure that its name and style flags match the typeface.
| virtual float Typeface::getAscent |
( |
| ) |
const |
|
pure virtual |
Returns the ascent of the font, as a proportion of its height.
The height is considered to always be normalised as 1.0, so this will be a value less that 1.0, indicating the proportion of the font that lies above its baseline.
Implemented in CustomTypeface.
| virtual float Typeface::getDescent |

const |
|
pure virtual |
Returns the descent of the font, as a proportion of its height.
The height is considered to always be normalised as 1.0, so this will be a value less that 1.0, indicating the proportion of the font that lies below its baseline.
Implemented in CustomTypeface.
| virtual float Typeface::getHeightToPointsFactor |

Returns the value by which you should multiply a juce font-height value to convert it to the equivalent point-size.
Implemented in CustomTypeface.
| virtual float Typeface::getStringWidth |
( |
const String & |
text | ) |
|
|
pure virtual |
Measures the width of a line of text.
The distance returned is based on the font having an normalised height of 1.0. You should never need to call this directly! Use Font::getStringWidth() instead!
Implemented in CustomTypeface.

Converts a line of text into its glyph numbers and their positions.
The distances returned are based on the font having an normalised height of 1.0. You should never need to call this directly! Use Font::getGlyphPositions() instead!

The path returned will be normalised to a font height of 1.0.

Returns a new EdgeTable that contains the path for the givem glyph, with the specified transform applied.
