Halftone
Stipple
Pointillism: dots placed by density, positions drawn from the seed.
Controls
- cell
- Side of one cell in source pixels. Dots are counted per cell, so a larger cell scatters them wider
- density
- How much ink the picture gets overall. Low leaves even the shadows sparse, with paper showing through
- dot size
- Changes the grain, not the tone: fewer large dots carry the same ink as many small ones
- jitter
- How far a dot may stray from the middle of its cell. At zero the scatter hardens into a grid
- contrast
- A number from -1 to 1, 0 by default.
- ink
- A colour, #000000 by default.
- paper
- A colour, #ffffff by default.
- invert
- On or off, off by default.
