Implementations

impl Viewport

pub fn new( physical_width: u32, physical_height: u32, scale_factor: f32, color_scheme: ColorScheme, ) -> Self

pub fn scale(&self) -> f32

Total scaling, computed as hidpi_scale_factor * zoom

pub fn scale_f64(&self) -> f64

Same as scale but f64 instead of f32

pub fn set_hidpi_scale(&mut self, scale: f32)

Set hidpi scale factor

pub fn zoom(&self) -> f32

Get document zoom level

pub fn set_zoom(&mut self, zoom: f32)

Set document zoom level (1.0 is unzoomed)

pub fn zoom_by(&mut self, zoom: f32)

pub fn zoom_mut(&mut self) -> &mut f32
