1.116.1 Instance variables

path <- closed: bool

If @on, the first and last points are connected.

Defaults: @off

path <- fill: colour|{foreground,background}*

Colour used to fill the interior of the path. To determine the interior, the Even-Odd-Rule is used.

Defaults: @nil (not filled)

path <- interpolation: chain*

When kind is smooth, this is a chain of interpolated points. The interpolation is recomputed each time the path has been modified and needs to be painted. See also graphical->request_compute.

See also

path-kind

path <- intervals: 0..100

The number of interpolation-points between each two successive specified points.

Defaults: Resource defined (10).

path <- kind: {poly,smooth}

Determines whether the line is smooth or a collection of line-segments (poly). For smooth path objects, the number of interpolated points is determined by path<->intervals and the chain object holding all interpolated points is available in path<-interpolation.

Defaults: poly (line segments).

path-interpolation

path <- mark: image*

When not @nil, each point of the path is marked using this image. Note that interpolation-points are not marked.

Defaults: @nil

path <- offset: point

Offset to origin. This offset is added to the location of the path<-points of the path if the path is painted. See also path->reference and path->relative_move.

path <- points: chain

Chain of points the line-segments goes through (control-points). The send-method validates and possibly converts all members of the argument chain to be instances of class point and raises the error unexpected_type on failure. On successs, it replaces the path<-points chain of the path with the argument. The argument thus becomes a part of the path object. See also path->initialise.

path <- radius: int

Rounding radius for the corners of poly lines. Not yet implemented.

Defaults: 0 (non-rounded corners).
