Enum AlphaCtrl 

#[repr(u8)]
pub enum AlphaCtrl {
    EMBEDDED = 0,
    OVERRIDE = 1,
    MULTIPLY = 2,
    ROPS = 3,
}

Variants

EMBEDDED = 0

Indicates that the AS pixel alpha value will be used to blend the AS with PS. The ALPHA field is ignored.

OVERRIDE = 1

Indicates that the value in the ALPHA field should be used instead of the alpha values present in the input pixels.

MULTIPLY = 2

Indicates that the value in the ALPHA field should be used to scale all pixel alpha values. Each pixel alpha is multiplied by the value in the ALPHA field.

ROPS = 3

Enable ROPs. The ROP field indicates an operation to be performed on the alpha surface and PS pixels.

Implementations

impl AlphaCtrl

pub const fn from_bits(val: u8) -> AlphaCtrl

pub const fn to_bits(self) -> u8

Trait Implementations

impl Clone for AlphaCtrl

fn clone(&self) -> AlphaCtrl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlphaCtrl

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

Formats the value using the given formatter.

impl From<AlphaCtrl> for u8

fn from(val: AlphaCtrl) -> u8

Converts to this type from the input type.

impl From<u8> for AlphaCtrl

fn from(val: u8) -> AlphaCtrl

Converts to this type from the input type.

impl Ord for AlphaCtrl

fn cmp(&self, other: &AlphaCtrl) -> 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,

Restrict a value to a certain interval.

impl PartialEq for AlphaCtrl

fn eq(&self, other: &AlphaCtrl) -> 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 PartialOrd for AlphaCtrl

fn partial_cmp(&self, other: &AlphaCtrl) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

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