Implementations

impl<'a> Vhea<'a>

pub fn version(&self) -> Version16Dot16

The major/minor version (1, 1)

pub fn ascender(&self) -> FWord

Typographic ascent.

pub fn descender(&self) -> FWord

Typographic descent.

pub fn line_gap(&self) -> FWord

Typographic line gap. Negative LineGap values are treated as zero in some legacy platform implementations.

pub fn advance_height_max(&self) -> UfWord

Maximum advance height value in ‘vmtx’ table.

pub fn min_top_side_bearing(&self) -> FWord

Minimum top sidebearing value in ‘vmtx’ table for glyphs with contours (empty glyphs should be ignored).

pub fn min_bottom_side_bearing(&self) -> FWord

Minimum bottom sidebearing value

pub fn y_max_extent(&self) -> FWord

Defined as max( tsb + (yMax-yMin)).

pub fn caret_slope_rise(&self) -> i16

Used to calculate the slope of the cursor (rise/run); 1 for vertical caret, 0 for horizontal.

pub fn caret_slope_run(&self) -> i16

0 for vertical caret, 1 for horizontal.

pub fn caret_offset(&self) -> i16

The amount by which a slanted highlight on a glyph needs to be shifted to produce the best appearance. Set to 0 for non-slanted fonts

pub fn metric_data_format(&self) -> i16

0 for current format.

pub fn number_of_long_ver_metrics(&self) -> u16

Number of LongMetric entries in ‘hmtx’/‘vmtx’ table
