Method: HexaPDF::Content::LineDashPattern.normalize

Defined in:

lib/hexapdf/content/graphics_state.rb

.normalize(array, phase = 0) ⇒ Object

:call-seq:

LineDashPattern.normalize(line_dash_pattern)         -> line_dash_pattern
LineDashPattern.normalize(array, phase = 0)          -> LineDashPattern.new(array, phase)
LineDashPattern.normalize(number, phase = 0)         -> LineDashPattern.new([number], phase)
LineDashPattern.normalize(0)                         -> LineDashPattern.new

Returns the arguments normalized to a valid LineDashPattern instance.

If array is 0, the default line dash pattern representing a solid line will be used. If it is a single number, it will be converted into an array holding that number.
