Enum ImageDownscale 

pub enum ImageDownscale {
    Fit(PxSize),
    Fill(PxSize),
}

Defines how an image is downscaled after decoding.

The image aspect ratio is preserved in both modes, the image is not upscaled, if it already fits the size constraints if will not be resized.

Variants

Fit(PxSize)

Image is downscaled so that both dimensions fit inside the size.

Fill(PxSize)

Image is downscaled so that at least one dimension fits inside the size.

Implementations

impl ImageDownscale

pub fn resize_dimensions(self, source_size: PxSize) -> PxSize

Compute the expected final size if the downscale is applied on an image of source_size.

Trait Implementations

impl Clone for ImageDownscale

fn clone(&self) -> ImageDownscale

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageDownscale

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ImageDownscale

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

fn from(fit: Px) -> Self

Fit splat

impl From<Size2D<Px, Px>> for ImageDownscale

fn from(fit: PxSize) -> Self

impl IntoVar<ImageDownscale> for PxSize

fn into_var(self) -> Var<ImageDownscale>

impl IntoVar<Option<ImageDownscale>> for ImageDownscale

fn into_var(self) -> Var<Option<ImageDownscale>>

impl PartialEq for ImageDownscale

fn eq(&self, other: &ImageDownscale) -> 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.
