Implementations§
source§impl<'a> Hhea<'a>
impl<'a> Hhea<'a>
sourcepub fn version(&self) -> MajorMinor
pub fn version(&self) -> MajorMinor
The major/minor version (1, 0)
sourcepub fn line_gap(&self) -> FWord
pub fn line_gap(&self) -> FWord
Typographic line gap. Negative LineGap values are treated as zero in some legacy platform implementations.
sourcepub fn advance_width_max(&self) -> UfWord
pub fn advance_width_max(&self) -> UfWord
Maximum advance width value in ‘hmtx’ table.
sourcepub fn min_left_side_bearing(&self) -> FWord
pub fn min_left_side_bearing(&self) -> FWord
Minimum left sidebearing value in ‘hmtx’ table for glyphs with contours (empty glyphs should be ignored).
sourcepub fn min_right_side_bearing(&self) -> FWord
pub fn min_right_side_bearing(&self) -> FWord
Minimum right sidebearing value; calculated as min(aw - (lsb + xMax - xMin)) for glyphs with contours (empty glyphs should be ignored).
sourcepub fn x_max_extent(&self) -> FWord
pub fn x_max_extent(&self) -> FWord
Max(lsb + (xMax-xMin))
sourcepub fn caret_slope_rise(&self) -> i16
pub fn caret_slope_rise(&self) -> i16
Used to calculate the slope of the cursor (rise/run); 1 for vertical caret, 0 for horizontal.
sourcepub fn caret_slope_run(&self) -> i16
pub fn caret_slope_run(&self) -> i16
0 for vertical caret, 1 for horizontal.
sourcepub fn caret_offset(&self) -> i16
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
sourcepub fn metric_data_format(&self) -> i16
pub fn metric_data_format(&self) -> i16
0 for current format.
sourcepub fn number_of_long_metrics(&self) -> u16
pub fn number_of_long_metrics(&self) -> u16
Number of LongMetric entries in ‘hmtx’/‘vmtx’ table
