[]Struct gfx_hal::window::CompositeAlpha

pub struct CompositeAlpha { /* fields omitted */ }

Specifies how the alpha channel of the images should be handled during compositing.

Methods

impl CompositeAlpha

pub const OPAQUE: CompositeAlpha

The alpha channel, if it exists, of the images is ignored in the compositing process. Instead, the image is treated as if it has a constant alpha of 1.0.

pub const PREMULTIPLIED: CompositeAlpha

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are expected to already be multiplied by the alpha channel by the application.

pub const POSTMULTIPLIED: CompositeAlpha

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are not expected to already be multiplied by the alpha channel by the application; instead, the compositor will multiply the non-alpha channels of the image by the alpha channel during compositing.

pub const INHERIT: CompositeAlpha

The way in which the presentation engine treats the alpha channel in the images is unknown to gfx-hal. Instead, the application is responsible for setting the composite alpha blending mode using native window system commands. If the application does not set the blending mode using native window system commands, then a platform-specific default will be used.

pub const fn empty() -> CompositeAlpha

Returns an empty set of flags

pub const fn all() -> CompositeAlpha

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<CompositeAlpha>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> CompositeAlpha

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: CompositeAlpha) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: CompositeAlpha) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: CompositeAlpha)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CompositeAlpha)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CompositeAlpha)

Toggles the specified flags in-place.

pub fn set(&mut self, other: CompositeAlpha, value: bool)

Inserts or removes the specified flags depending on the passed value.
