Enum sdl2::render::BlendMode

#[repr(i32)]pub enum BlendMode {
    None,
    Blend,
    Add,
    Mod,
    Invalid,
}

Blend mode for Canvas, Texture or Surface.

Variants

None

no blending (replace destination with source).

Blend

Alpha blending

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

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

Add

Additive blending

dstRGB = (srcRGB * srcA) + dstRGB

dstA = dstA (keep original alpha)

Mod

Color modulate

dstRGB = srcRGB * dstRGB

Invalid

Invalid blending mode (indicates error)
