Enum TileMode 

pub enum TileMode {
    Clamp,
    Repeat,
    Decal,
    Mirror,
}

What happens outside an image’s own bounds.

Variants

Clamp

Hold the edge pixel. The usual choice for drawing an image once.

Repeat

Repeat the image, tiling the plane.

Decal

Draw nothing outside the image.

Distinct from clamping in the only case that matters: a shape larger than the image it is filled with. Clamping smears the border across the remainder, which reads as a rendering fault rather than as a choice.

Mirror

Repeat, reversing every other copy.

What repeating is for when the two ends do not match. A ramp tiled by TileMode::Repeat jumps from its last color back to its first at every period, and that discontinuity is a visible seam; reflecting each alternate copy joins end to end and leaves none. The period is twice as long, since a copy and its reflection make one.
