## Revision history
|
||||
|
||||
| date | change |
|
||||
|:--|:--|
|
||||
| 2026-10-13 | Memory: layers traced within the box of their pixels and a few at a time (16 megapixel photo: 3.9 GB to 0.9 GB) |
|
||||
| 2026-10-13 | Shared edges: outlines are cut at their junctions and each piece is fitted once, the same from either side |
|
||||
| 2026-10-13 | Photos: continuous-tone images are smoothed within their tones before quantising, and stacked layers go by lightness |
|
||||
| 2026-10-13 | The palette: made of the picture's own colours, noise-made colours merged, blend pixels settled, cuts where colours differ most, colours compared in Oklab |
