Expand description

CBLC — Color Bitmap Location Table

Fields§

§major_version: u16

Major version of this table.

2 for EBLC, 3, for CBLC

§minor_version: u16

Minor version of this table.

§bitmap_sizes: Vec<BitmapSize<'a>>

Array of “strikes” available for this font.

Implementations§

Source §

impl<'a> CBLCTable<'a>

Source

pub fn find_strike( &self, glyph_id: u16, target_ppem: u8, max_bit_depth: BitDepth, ) -> Option<MatchingStrike<'_, 'a>>

Find a strike matching the supplied criteria.

glyph_id is the glyph to lookup.
target_ppem is the desired size. If an exact match can’t be found the nearest one will be returned, favouring being oversize vs. undersized.
max_bit_depth is the maximum accepted bit depth of the bitmap to return. If you accept all bit depths then use BitDepth::ThirtyTwo.
