Enum gstreamer_video::VideoAlphaMode

#[non_exhaustive]
pub enum VideoAlphaMode {
    Copy,
    Set,
    Mult,
}

Different alpha modes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Copy

When input and output have alpha, it will be copied. When the input has no alpha, alpha will be set to GST_VIDEO_CONVERTER_OPT_ALPHA_VALUE

Set

set all alpha to GST_VIDEO_CONVERTER_OPT_ALPHA_VALUE

Mult

multiply all alpha with GST_VIDEO_CONVERTER_OPT_ALPHA_VALUE. When the input format has no alpha but the output format has, the alpha value will be set to GST_VIDEO_CONVERTER_OPT_ALPHA_VALUE

Formats the value using the given formatter.

impl From<VideoAlphaMode> for Value

fn from(v: VideoAlphaMode) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for VideoAlphaMode

type Checker = GenericValueTypeChecker<VideoAlphaMode>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for VideoAlphaMode

impl Ord for VideoAlphaMode

fn cmp(&self, other: &VideoAlphaMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

impl PartialEq for VideoAlphaMode

fn eq(&self, other: &VideoAlphaMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
