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

impl<'a> CBLCTable<'a>

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.
