Manual/Graph/Global Style

There are two sets of style features to affect the look of the knot: Knot Display and Knot Style.

Knot Display

The style options in Knot Display affect the entire graph, and they affect how the graph is displayed but its shape is not altered. These features are those that can be changed on an exported SVG without changing the path control points.

Colors

Depending on the design there may be multiple ropes that make the knot, specifying multiple colors will cycle the defined colors when drawing each rope. If only a single color is defined, the entire knot will have that color. Knotter also supports automatic coloring that assigns a distinct color to each rope in the knot, this may be useful to study the topology of that knot.

• 

  A knot with a single color

• 

  The same knot with two user defined color

• 

  The same knot with automatic coloring

Width

The width is the thickness of the rope tied in the knot.

• 

  Width 30px

• 

  Width 5px

Joint Style

If the knot style results in some sharp angles, this affects how they are displayed.

• 

  Bevel

• 

  Miter

• 

  Round

Knot Style

The options in Knot Style instead affect the shape itself. Their exact meaning depends on the edge type and cusp shape. Every feature in Knot Style can be configured on a per-node basis via the Selection Style dialog.

Curve

Size of the curve control handles, its behaviour depends on the edge type. In general, it controls the way a ropes approaches the center of an edge and the cusp point.

Gap

Distance between the ends of a loop then a rope passes under another rope. It may change meaning for different edge types.

Angle

Minimum angle between edges for which a cusp shall be drawn.

Distance

Distance of the cusp point from the node position.

Style

The style used to draw a cusp.
