Remarks
Determines how the strokes with dash patterns and other patterns (tiled pictures, placement effects) are handled at the end points of the line geometry's segments. If more than one pattern exists (for example, a dashed simple stroke, a hash stroke, and a marker stroke) then the longest pattern's length is affected directly by this option and the rest of the stroke patterns are resized proportionately to match.
