Struct SDL_BlendFactor

Help

#[repr(transparent)]
pub struct SDL_BlendFactor(pub i32);

Available on crate feature dep_sdl3 only.

Expand description

The normalized factor used to multiply pixel components.

The blend factors are multiplied with the pixels from a drawing operation (src) and the pixels from the render target (dst) before the blend operation. The comma-separated factors listed above are always applied in the component order red, green, blue, and alpha.

§Availability

This enum is available since SDL 3.2.0.
