PLAYABLE PIXELS · LIVE SPACE HEAT · NO UPLOAD

Play with a living sticker sheet.

Drag, resize and rotate real pixels on the sheet. Watch space and overlap feedback live; run preflight only when you want exact PDF/SVG evidence.

Pointer tilt and the inspection lens are visual digital-sheet aids. Arrow keys move the selected sticker. F toggles focus view and Escape exits it. Physical cutter fit is not assessed.

METHOD

What is actually computed

  1. Exact container boundaries reject animation, trailing payload, SVG/HTML polyglots and oversized decode surfaces.
  2. Marching squares traces raster alpha; deterministic simplification and bounded offsets expose islands, holes and narrow features.
  3. MaxRects and row packers use fixed tie breaks. The PDF page box uses exact mm-to-point conversion; decoded pixels are re-encoded without source metadata.

BOUNDARY

A digital preflight, not a cutter promise

The PDF and SVG include no registration or sensor marks. They are not Cricut-ready, Silhouette-ready, vendor-certified or proof that a printer/cutter/material will work. Official vendor software can rescale externally saved PDFs and uses machine-dependent, non-rectangular cuttable areas; rebuild those constraints there and test physically.
