Enum SurfaceType 

pub enum SurfaceType {
    SRgb,
    LinearRgb,
    AlphaOnly,
}

Types of pixel data in a ImageSurface.

Variants

SRgb

The pixel data is in the sRGB color space.

LinearRgb

The pixel data is in the linear sRGB color space.

AlphaOnly

The pixel data is alpha-only (contains meaningful data only in the alpha channel).

A number of methods are optimized for alpha-only surfaces. For example, linearization and unlinearization have no effect for alpha-only surfaces.

Implementations

impl SurfaceType

pub fn combine(self, other: SurfaceType) -> SurfaceType

Combines surface types

If combining two alpha-only surfaces, the result is alpha-only. If one is alpha-only, the result is the other. If none is alpha-only, the types should be the same.

Panics

Panics if the surface types are not alpha-only and differ.

Trait Implementations

impl Clone for SurfaceType

fn clone(&self) -> SurfaceType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurfaceType

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

Formats the value using the given formatter.

impl From<ColorInterpolationFilters> for SurfaceType

fn from(c: ColorInterpolationFilters) -> Self

Converts to this type from the input type.

impl Hash for SurfaceType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SurfaceType

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