Struct SubstFont 

pub struct SubstFont {
    pub charset: Charset,
    pub italic_angle: i32,
    pub is_builtin_generic: bool,
    /* private fields */
}

The record a substitution produces.

weight and weight_cjk are Option where PDFium overloads 0 to mean “the face’s natural weight” (D12). The sentinel is real behavior — it makes the embolden level 0 and the Multiple-Master axis take its default — so the mapping back to 0 happens at the two places the arithmetic needs it, not silently at construction.

Fields

charset: Charset

The charset the face was chosen for.

italic_angle: i32

The synthetic italic angle, in degrees. Negative slants right.

is_builtin_generic: bool

Whether this is one of the two built-in Multiple-Master generics, which suppresses artificial emboldening entirely — the design space handles weight properly, so dilating on top would double-count it.

Implementations

impl SubstFont

pub fn raw_weight(&self) -> i32
