Stitch Maker — le convertisseur
The engine: a photo goes in, a cross-stitch chart comes out — DMC thread palette, symbols and a printable pattern. This is where all the colour work happens.

Fiche de réalisation
Stitch Maker — le convertisseur
Reducing several million shades to the few hundred threads actually sold is a problem of perception, not arithmetic: comparing colours in RGB turns faces green.
What I do there
- Colour matching in CIELab: the DMC palette is converted once, then each shade in the image finds its thread by perceptual distance rather than RGB distance
- A canonical JSON pattern — grid, palette, symbols — the single source behind the preview, the printable file and progress tracking
- PDF pattern laid out to the conventions Pattern Keeper expects, a format reverse-engineered and documented
- Cost announced before starting: derived from the requested size and colour count, reserved, then debited under a lock so it can never be charged twice
- Conversion handled outside the request, with credits refunded automatically on failure
