Struct figures::DisplayScale

pub struct DisplayScale<T> { /* fields omitted */ }

Scaling ratios for Scaled and Displayable.

Implementations

impl<T: Mul<T, Output = T> + Copy> DisplayScale<T>

pub fn dpi_scale(&self) -> Scale<T, Points, Pixels>

Returns the scale between Pixels and Points.

pub fn additional_scale(&self) -> Scale<T, Scaled, Points>

Returns the scale between Points and Scaled.

pub fn total_scale(&self) -> Scale<T, Scaled, Pixels>

Returns the scale between Pixels and Scaled.

pub fn set_additional_scale(&mut self, scale: Scale<T, Scaled, Points>)

Sets the scale factor between Points and Scaled.

pub fn set_dpi_scale(&mut self, scale: Scale<T, Points, Pixels>)

Sets the scale factor between Pixels and Points.

impl<T: Mul<T, Output = T> + Copy> DisplayScale<T>

pub fn new(
    dpi: Scale<T, Points, Pixels>,
    additional_scaling: Scale<T, Scaled, Points>
) -> Self

Returns a new instance with the two scales provided.

• dpi: This scale represents the scaling between Pixels and Points. It should be set to the system configured user interface scaling, if possible. In general, this scale shouldn’t be something an end-user manually configures.
• additional_scaling: This scale represents the scaling between Points and Scaled. This is an additional layer of scaling on top of the dpi scaling. It is intended to be used to provide a way for applications to allow end-users to configure an application-specific zoom setting.
