Enum ImageAutoScale 

pub enum ImageAutoScale {
    Pixel,
    Factor,
    Density,
}

Image auto scale mode.

Images can be auto scaled to display a a size normalized across screens.

Variants

Pixel

Don’t auto scale, image is sized by pixel size.

Note that most widgets are scaled by the screen factor (DIP units), so the image will appear to have different sizes depending on the screen.

Factor

Image is scaled by the screen scale factor, similar to DIP unit.

This is the default, it makes the image appear to have the same proportional size as other widgets independent of the screen that is displaying it.

Density

Image is scaled by the physical size metadata of the image and the screen with the intent of displaying at the print size.

Trait Implementations

impl Clone for ImageAutoScale

fn clone(&self) -> ImageAutoScale

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageAutoScale

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageAutoScale

fn default() -> ImageAutoScale

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImageAutoScale

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<bool> for ImageAutoScale

fn from(factor: bool) -> Self

Converts to this type from the input type.

impl IntoVar<ImageAutoScale> for bool

fn into_var(self) -> Var<ImageAutoScale>

impl PartialEq for ImageAutoScale

fn eq(&self, other: &ImageAutoScale) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ImageAutoScale

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
