Circle packing
Circles packed by tone: smaller where the image is darker.
Controls
- min radius
- The smallest circle allowed. Together with the largest it sets how far tone can stretch the grain
- max radius
- The largest circle allowed
- attempts
- How many candidates are tried. The density knob and the whole cost of a frame in one
- spacing
- Gap between circles. At zero they touch
- tone
- Which end gets the small tight circles: the shadows, the way ink behaves, or the highlights, for glowing work on dark
- stroke
- Draws rings instead of discs — the same packing, outlined
- contrast
- A number from -1 to 1, 0 by default.
- background
- A colour, #000000 by default.
