Enum ImageScalingAlgorithm 

pub enum ImageScalingAlgorithm {
    Auto,
    Smooth,
    Pixelated,
}

Defines how images should be scaled when rendered.

Variants

Auto

The image is scaled using Catmull-Rom interpolation. This is balanced for speed and quality.

Smooth

The image is scaled using Lanczos3 resampling. This provides high-quality scaling but may be slower.

Pixelated

The image is scaled using nearest neighbor interpolation, which is suitable for pixel art or images where sharp edges are desired.

Trait Implementations

impl Clone for ImageScalingAlgorithm

fn clone(&self) -> ImageScalingAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ImageScalingAlgorithm

impl Debug for ImageScalingAlgorithm

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

Formats the value using the given formatter.

impl Default for ImageScalingAlgorithm

fn default() -> ImageScalingAlgorithm

Returns the “default value” for a type.

impl From<ImageScalingAlgorithm> for FilterType

fn from(algorithm: ImageScalingAlgorithm) -> Self

Converts to this type from the input type.

impl<'i> FromCss<'i> for ImageScalingAlgorithm

const VALID_TOKENS: &'static [CssToken]

Returns the list of valid CSS tokens for this type.

fn from_css(input: &mut Parser<'i, '_>) -> ParseResult<'i, Self>

Parses the type from a Parser instance.

fn from_str(source: &'i str) -> ParseResult<'i, Self>

where Self: Sized,

Helper function to parse the type from a string.

const EXPECT_MESSAGE: CssExpectedMessage = CssExpectedMessage::OneValue

Message template used when building parse errors for this type.

impl PartialEq for ImageScalingAlgorithm

fn eq(&self, other: &ImageScalingAlgorithm) -> 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 StructuralPartialEq for ImageScalingAlgorithm

impl ToCss for ImageScalingAlgorithm

fn to_css<W: Write>(&self, dest: &mut W) -> Result

Write the CSS representation of this value into dest.
