OptimizeLevel

docs.rs
Enumin image_optimizerfastly 0.13.1View source
pub enum OptimizeLevel {
    Low = 1,
    Medium = 2,
    High = 3,
}

The optimize parameter automatically applies optimal quality compression to produce an output image with as much visual fidelity as possible, while minimizing the file size.

Variants

Low

= 1

Output image quality will be similar to the input image quality.

Medium

= 2

More optimization is allowed, while attempting to preserve the visual quality of the input image.

High

= 3

Minor visual artifacts may be visible. This produces the smallest file.
