Struct pdf::FontRef
[−]
[src]
pub struct FontRef { /* 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 everything needed to build a font dictionary, while a FontRef is the name that can be used in a page stream to use a font. Calling Canvas::get_font will make sure the font dictionary is created in the file, associate it with a name in the page resources and return a FontRef representing that name.
The serif
variable in
the TextObject example is a FontRef.
Methods
impl FontRef
[src]
fn get_encoding(&self) -> Encoding
Get the encoding used by the referenced font.
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.
