struct | ContainerDeletePolicy< HintingParams > |
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.
A handy typedef for a pointer to a typeface.

virtual |
Destructor.
void Typeface::applyVerticalHintingTransform | ( | float | fontHeight, |
Path & | path | ||
) |
Makes an attempt at performing a good overall distortion that will scale a font of the given size to align vertically with the pixel grid. The path should be an unscaled (i.e. normalised to height of 1.0) path for a glyph.
|
static |
Clears any fonts that are currently cached in memory.
|
static |
Creates a new system typeface.
|
static |
Attempts to create a font from some raw font file data (e.g. a TTF or OTF file image). The system will take its own internal copy of the data, so you can free the block once this method has returned.
|
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 WindowsTypeface, AndroidTypeface, and CustomTypeface.
|
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 WindowsTypeface, AndroidTypeface, and CustomTypeface.
|
virtual |
Returns a new EdgeTable that contains the path for the givem glyph, with the specified transform applied.
Reimplemented in AndroidTypeface, and CustomTypeface.
|
staticprotected |
|
pure virtual |
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!
Implemented in WindowsTypeface, AndroidTypeface, and CustomTypeface.
|
pure virtual |
Returns the value by which you should multiply a juce font-height value to convert it to the equivalent point-size.
Implemented in WindowsTypeface, AndroidTypeface, and CustomTypeface.
Returns the font family of the typeface.
Returns the outline for a glyph. The path returned will be normalised to a font height of 1.0.
Implemented in WindowsTypeface, AndroidTypeface, and CustomTypeface.
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 WindowsTypeface, AndroidTypeface, and CustomTypeface.
Returns the font style of the typeface.
|
inlinevirtual |
Returns true if the typeface uses hinting.
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.
On some platforms, this allows a specific path to be scanned. Currently only available when using FreeType.
|
static |
Changes the number of fonts that are cached in memory.
