QR mosaic
A grid of code modules with the finder patterns of a real code.
Controls
- module
- Side of one module in source pixels. Everything else is measured in it: a finder square is exactly seven modules
- markers
- The three finder squares and the timing track between them. They are what makes this a code — without them it is a threshold on a grid
- threshold
- The brightness at which a module goes dark
- dither
- Moves the threshold from module to module so a gradient survives. At zero it is one hard cut, which is what a real code has
- contrast
- A number from -1 to 1, 0 by default.
- ink
- A colour, #101010 by default.
- paper
- A colour, #f2f2f2 by default.
