Struct BitmapStrikes

pub struct BitmapStrikes<'a>(StrikesKind<'a>);

Set of strikes, each containing embedded bitmaps of a single size.

Tuple Fields

0: StrikesKind<'a>

Implementations

impl<'a> BitmapStrikes<'a>

pub fn new(font: &FontRef<'a>) -> Self

Creates a new BitmapStrikes for the given font.

This will prefer sbix, CBDT, and CBLC formats in that order.

To select a specific format, use with_format.

pub fn with_format(font: &FontRef<'a>, format: BitmapFormat) -> Option<Self>

Creates a new BitmapStrikes for the given font and format.

Returns None if the requested format is not available.

pub fn format(&self) -> Option<BitmapFormat>

Returns the format representing the underlying table for this set of strikes.

pub fn len(&self) -> usize

Returns the number of available strikes.

pub fn is_empty(&self) -> bool

Returns true if there are no available strikes.

pub fn get(&self, index: usize) -> Option<BitmapStrike<'a>>

Returns the strike at the given index.

pub fn glyph_for_size( &self, size: Size, glyph_id: GlyphId, ) -> Option<BitmapGlyph<'a>>

Returns the best matching glyph for the given size and glyph identifier.

In this case, “best” means a glyph of the exact size, nearest larger size, or nearest smaller size, in that order.

pub fn iter(&self) -> impl Iterator<Item = BitmapStrike<'a>> + 'a + Clone

Returns an iterator over all available strikes.

Trait Implementations

impl<'a> Clone for BitmapStrikes<'a>

fn clone(&self) -> BitmapStrikes<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
