Enum zng::image::ImageFit

pub enum ImageFit {
    None,
    Fill,
    Contain,
    Cover,
    ScaleDown,
}

Image layout mode.

This layout mode can be set to all images inside a widget using img_fit, the image_presenter uses this value to calculate the image final size.

The image desired size is its original size, either in pixels or DIPs after cropping and scaling.

Variants

None

The image original size is preserved, the image is clipped if larger then the final size.

Fill

The image is resized to fill the final size, the aspect-ratio is not preserved.

Contain

The image is resized to fit the final size, preserving the aspect-ratio.

Cover

The image is resized to fill the final size while preserving the aspect-ratio. If the aspect ratio of the final size differs from the image, it is clipped.

ScaleDown

If the image is smaller then the final size applies the None layout, if its larger applies the Contain layout.

Trait Implementations

impl Clone for ImageFit

fn clone(&self) -> ImageFit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageFit

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ImageFit

fn deserialize<__D>( __deserializer: __D, ) -> Result<ImageFit, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ImageFit

fn eq(&self, other: &ImageFit) -> 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 ImageFit

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
