Enum sdl2::render::BlendMode

#[repr(i32)]
pub enum BlendMode {
    None = 0,
    Blend = 1,
    Add = 2,
    Mod = 4,
    Mul = 8,
    Invalid = 2_147_483_647,
}

Blend mode for Canvas, Texture or Surface.

Variants

None = 0

no blending (replace destination with source).

Blend = 1

Alpha blending

dstRGB = (srcRGB * srcA) + (dstRGB * (1-srcA))

dstA = srcA + (dstA * (1-srcA))

Add = 2

Additive blending

dstRGB = (srcRGB * srcA) + dstRGB

dstA = dstA (keep original alpha)

Mod = 4

Color modulate

dstRGB = srcRGB * dstRGB

Mul = 8

Color multiply

Invalid = 2_147_483_647

Invalid blending mode (indicates error)

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl Hash for BlendMode

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 BlendMode

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

impl TryFrom<u32> for BlendMode

type Error = ()

The type returned in the event of a conversion error.

fn try_from(n: u32) -> Result<Self, Self::Error>

Performs the conversion.
