data: &'a [u8]

Implementations

impl<'a> Table<'a>

pub fn parse(data: &'a [u8]) -> Option<Self>

Parses a table from raw data.

pub fn weight(&self) -> Weight

Returns weight class.

pub fn width(&self) -> Width

Returns face width.

pub fn permissions(&self) -> Option<Permissions>

Returns face permissions.

Returns None in case of a malformed value.

pub fn is_subsetting_allowed(&self) -> bool

Checks if the face allows embedding a subset, further restricted by Self::permissions.

pub fn is_outline_embedding_allowed(&self) -> bool

Checks if the face allows outline data to be embedded.

If false, only bitmaps may be embedded in accordance with Self::permissions.

If the font contains no bitmaps and this flag is not set, it implies no embedding is allowed.

pub fn subscript_metrics(&self) -> ScriptMetrics

Returns subscript metrics.

pub fn superscript_metrics(&self) -> ScriptMetrics

Returns superscript metrics.

pub fn strikeout_metrics(&self) -> LineMetrics

Returns strikeout metrics.

pub fn unicode_ranges(&self) -> UnicodeRanges

Returns Unicode ranges.

fn fs_selection(&self) -> u16

pub fn style(&self) -> Style

Returns style.

pub fn is_bold(&self) -> bool

Checks if face is bold.

Do not confuse with Weight::Bold.

pub fn use_typographic_metrics(&self) -> bool

Checks if typographic metrics should be used.

pub fn typographic_ascender(&self) -> i16

Returns typographic ascender.

pub fn typographic_descender(&self) -> i16

Returns typographic descender.

pub fn typographic_line_gap(&self) -> i16

Returns typographic line gap.

pub fn windows_ascender(&self) -> i16

Returns Windows ascender.

pub fn windows_descender(&self) -> i16

Returns Windows descender.

pub fn x_height(&self) -> Option<i16>

Returns x height.

Returns None version is < 2.

pub fn capital_height(&self) -> Option<i16>
