## What is Ditherdeck?

Ditherdeck is a focused ordered-dither laboratory for comparing thresholds and 2x2, 4x4, or 8x8 Bayer-style matrices against a deterministic grayscale test field.

WHAT IT DOES
- Preview a deterministic 16x16 source field with no network dependency
- Adjust the threshold continuously
- Switch among 2x2, 4x4, and 8x8 ordered matrices
- Compare geometry and packing calculations in the supporting analysis workspace

PRIVATE BY DEFAULT
No account, advertising, tracking, analytics SDK, or subscription. Workspace data stays in the app container. Imports, scans, device access, and network actions happen only when you request them.

ONE PURCHASE
The complete core tool, local workspace, records, analysis, export, and offline reference are included in the paid download.

IMPORTANT BOUNDARY
Exported bytes still require review against the exact target controller, palette order, and driver.
