Enum gfx_hal::image::Filter

[−] Show declaration

pub enum Filter {
    Nearest,
    Linear,
}

[−] Expand description

How to filter the image when sampling. They correspond to increasing levels of quality, but also cost.

Variants

Nearest

[−] Expand description

Selects a single texel from the current mip level and uses its value.

Mip filtering selects the filtered value from one level.

Linear

[−] Expand description

Selects multiple texels and calculates the value via multivariate interpolation.

• 1D: Linear interpolation
• 2D/Cube: Bilinear interpolation
• 3D: Trilinear interpolation
