Declaration

TJoinStyle = (jsMiter, jsBevel, jsRound, jsRoundEx, jsSquare);
TJoinStyles = set of TJoinStyle;

Description

TJoinStyle defines how corner vertices between adjacent polyline segments are joined during stroke outline generation in routines such as BuildPolyPolyLine, PolylineFS, and PolyPolylineFS.

Enum Values

Value	Description	Example
jsMiter	Outer edges are extended to intersect at a sharp point. If the angle of the corner is very sharp and exceeds MiterLimit, the join falls back to a bevel join.
jsBevel	Corners are cut flat perpendicular to the vertex bisector.
jsRound	Convex joins are rounded using circular arc approximation.
jsRoundEx	Both convex and concave joins are rounded. Convex join rounding depth is controlled by MiterLimit.
jsSquare	Corners are extended outwards by half the stroke width with flat square caps.
