Enum tetra::graphics::BlendOperation

pub enum BlendOperation {
    Add,
    Subtract,
    ReverseSubtract,
    Min,
    Max,
}

Defines a formula for blending two color or alpha values.

Variants

Add

Blends by adding the source and the destination together.

(srcValue * srcBlendFactor) + (dstValue * dstBlendFactor)

Subtract

Blends by subtracting the destination from the source.

(srcValue * srcBlendFactor) - (dstValue * dstBlendFactor)

ReverseSubtract

Blends by subtracting the source from the destination.

(dstValue * dstBlendFactor) - (srcValue * srcBlendFactor)

Min

Blends by picking the minimum of the source and destination.

min((srcValue * srcBlendFactor), (dstValue * dstBlendFactor))

Max

Blends by picking the maximum of the source and destination.

max((srcValue * srcBlendFactor), (dstValue * dstBlendFactor))

Trait Implementations

impl Clone for BlendOperation

fn clone(&self) -> BlendOperation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendOperation

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

Formats the value using the given formatter.

impl PartialEq<BlendOperation> for BlendOperation

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