DashedStrokePattern

A stroke pattern of alternating dashes and gaps, defined by segments.

Inherits: StrokePattern

Properties

  • pattern_fit - Determines how this stroke pattern should be fit to a line when their lengths are not equal or multiples.
  • segments - A list of even length with a minimum of 2, in the form of [a₁, b₁, (a₂, b₂, ...)], where a should be the length of segments in 'units', and b the length of the space after each segment in units.

segments: list[Number]

A list of even length with a minimum of 2, in the form of [a₁, b₁, (a₂, b₂, ...)], where a should be the length of segments in 'units', and b the length of the space after each segment in units. Both values must be strictly positive.

'Units' refers to pixels, unless the pattern has been scaled due to the pattern_fit being flet_map.PatternFit.SCALE_UP.

If more than two items are specified, then each segments will alternate/iterate through the values.

For example, [50, 10, 10, 10] will cause:

  • a segment of length 50px
  • followed by a space of 10px
  • followed by a segment of length 10px
  • followed by a space of 10px
  • followed by a segment of length of 50px
  • followed by a space of 10px
  • and so on ...

Raises:

  • ValueError - If the list does not contain at least two items, or if its length is not even.
