/FontFamily — the font family name.

§flags: u32

/Flags — a collection of boolean attributes (see flag constants).

§font_b_box: Option<[f64; 4]>

/FontBBox — bounding box for all glyphs [llx lly urx ury].

§italic_angle: f64

/ItalicAngle — angle in degrees counter-clockwise from vertical.

§ascent: f64

/Ascent — maximum height above the baseline.

§descent: f64

/Descent — maximum depth below the baseline (typically negative).

§cap_height: Option<f64>

/CapHeight — top of flat capital letters.

/MaxWidth — maximum glyph width.

§missing_width: Option<f64>

/MissingWidth — width to use for undefined character codes.

§leading: Option<f64>

/Leading — desired spacing between lines of text.

§font_file_ref: Option<IndirectRef>

/FontFile — reference to embedded Type1 font program.

Implementations§

Source §

impl FontDescriptor

Source

pub const FIXED_PITCH: u32 = 1

All glyphs have the same width.

Source

pub const SERIF: u32

Glyphs have serifs.

Source

pub const SYMBOLIC: u32

Font uses a symbol character set.

Source

pub const SCRIPT: u32

Glyphs resemble cursive handwriting.

Source

pub const NONSYMBOLIC: u32

Font uses a standard (non-symbol) character set.

Source

pub const ITALIC: u32

Glyphs have dominant slant.

Source

pub const ALL_CAP: u32

No lowercase letters; small letters rendered as small capitals.

Source

pub const SMALL_CAP: u32

Lowercase letters rendered as smaller versions of uppercase.

Source

pub const FORCE_BOLD: u32

Bold glyphs shall be painted with extra thickness at small sizes.

Source

pub fn has_flag(&self, flag: u32) -> bool

Check whether the given flag bit is set.

Source

pub fn is_fixed_pitch(&self) -> bool

Returns true if the font is fixed-pitch.

Source

pub fn is_symbolic(&self) -> bool

Returns true if the font is symbolic.

Source

pub fn is_italic(&self) -> bool

Returns true if the font is italic.
