This structure contains all attributes required for path stroking.
Path stroking is the process of drawing a polygon with a thick
pen. The various attributes contained in this structure can be
used to customize that process.
Before performing the actual comparison, implementations will
multiply the MiterLimit with the current StrokeWidth, such
that, with phi being the angle between the two joining
segments, MiterLimit=1/sin(phi/2.0).
Array of ink on and off lengths, measured in user coordinate
space.
The first element specifies the length of the first 'on'
segment of the dashing, the second element the length of the
first 'off' segment, and so forth. Give zero elements here for
solid strokes. This array always have an even number of
elements, with zero, as usual, counting as even
here. Furthermore, each entry in this array must have a value
that is positive (or 0.0)
Array of line widths and spacings for multiple-line
strokes.
The entries here are relative to the
StrokeAttributes::StrokeWidth attribute
above, i.e. the total width of all lines and spacings will
always equal
StrokeAttributes::StrokeWidth. The first
element specifies the width of the rightmost line, when
travelling from the start point of the path to the end
point. The second element specifies the space between the
first line and the second line, and so forth. If the array
ends with a spacing, this spacing is included in the total
width of the multiple-line stroke. That is, the stroke becomes
asymmetric.
After every sub-stroke, i.e. after every line or curve segment
within a single path polygon, a shape of this type is inserted
into the stroke to glue the segments together. Please note
that distinct polygons within the path poly-polygon are not
connected, and therefore also not joined via the shape
specified here.
