Trait printpdf::types::plugins::graphics::two_dimensional::font::FontData

pub trait FontData: FontDataClone + Debug {
    pub fn font_metrics(&self) -> FontMetrics;
    pub fn glyph_id(&self, c: char) -> Option<u16>;
    pub fn glyph_ids(&self) -> HashMap<u16, char>;
    pub fn glyph_metrics(&self, glyph_id: u16) -> Option<GlyphMetrics>;
}

Provides access to font metrics.

Per default, printpdf uses rusttype to extract the font data. You can implement this trait for other types if you want to use a different font backend.

Required methods

pub fn font_metrics(&self) -> FontMetrics

Returns the unscaled metrics for this font.

pub fn glyph_id(&self, c: char) -> Option<u16>

Returns the glyph id for a Unicode character if it is present in this font.

pub fn glyph_ids(&self) -> HashMap<u16, char>

Returns a mapping from glyph IDs to Unicode characters for all supported characters.

pub fn glyph_metrics(&self, glyph_id: u16) -> Option<GlyphMetrics>

Returns the glyph metrics for a glyph of this font, if available.
