D2D1_LINE_JOIN enumeration (d2d1.h)

  • Article

Describes the shape that joins two lines or segments.

Syntax

typedef enum D2D1_LINE_JOIN {
  D2D1_LINE_JOIN_MITER = 0,
  D2D1_LINE_JOIN_BEVEL = 1,
  D2D1_LINE_JOIN_ROUND = 2,
  D2D1_LINE_JOIN_MITER_OR_BEVEL = 3,
  D2D1_LINE_JOIN_FORCE_DWORD = 0xffffffff
} ;

Constants

 
D2D1_LINE_JOIN_MITER
Value: 0
Regular angular vertices.
D2D1_LINE_JOIN_BEVEL
Value: 1
Beveled vertices.
D2D1_LINE_JOIN_ROUND
Value: 2
Rounded vertices.
D2D1_LINE_JOIN_MITER_OR_BEVEL
Value: 3
Regular angular vertices unless the join would extend beyond the miter limit; otherwise, beveled vertices.
D2D1_LINE_JOIN_FORCE_DWORD
Value: 0xffffffff

Remarks

A miter limit affects how sharp miter joins are allowed to be. If the line join style is D2D1_LINE_JOIN_MITER_OR_BEVEL, then the join will be mitered with regular angular vertices if it doesn't extend beyond the miter limit; otherwise, the line join will be beveled.

The following illustration shows different line join settings for the same stroked path geometry.
