Enum Density 

#[non_exhaustive]
pub enum Density {
    Auto {
        page_size: u32,
    },
    Fixed {
        texels_per_unit: f32,
        page_size: Option<u32>,
    },
}

How texel density and page size are chosen.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

The highest density at which everything fits one page_size × page_size page. The page is then cropped to the rows actually used, so Atlas::height may be less than page_size. If the charts can’t share one page at any density (very many charts, or padding too large for the page), several pages are used at a lower density.

Fields

page_size: u32

Page width (and maximum height) in texels; > 2 × padding.

Fixed

A fixed density, for consistent texel size across separately unwrapped atlases (how engines size lightmaps).

Fields

texels_per_unit: f32

Texels per world unit. Must be finite and > 0.

page_size: Option<u32>

None: one page that grows to fit (cropped to its content). Some(size): as many size × size pages as needed; fails with Error::ChartTooLarge if a chart can’t fit one.
