Struct pdf::FontRef

pub struct FontRef {
    // some fields omitted
}

A font ready to be used in a TextObject.

The way to get FontRef is to call Canvas::get_font with a FontSource. In PDF terms, a FontSource is a font dictionary, and a FontRef is a name registered with a font source in the page resources, like /F1.

Methods

impl FontRef

fn new(n: usize, encoding: Encoding, metrics: Arc<FontMetrics>) -> FontRef

fn get_encoding(&self) -> Encoding

fn get_width(&self, size: f32, text: &str) -> f32

Get the width of the given text in this font at given size.

fn get_width_raw(&self, text: &str) -> u32

Get the width of the given text in thousands of unit of text space. This unit is what is used in some places internally in pdf files and in some methods on a TextObject.
