for the two segments are extended until they meet at an angle. If the segments meet at too sharp an angle
(such that the miter would extend from the intersection of the segments a distance greater than the product of the miter limit
value and the
border radius
), then a bevel join
(see above
) is used instead. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter line join as used in PostScript and PDF.<
