EdgeForm

EdgeForm[g]

is a graphics directive that specifies that edges of polygons and other filled graphics objects are to be drawn using the graphics directive or list of directives g.

Details

  • EdgeForm[] draws no edges.
  • EdgeForm works in both 2D and 3D.
  • Color, opacity, thickness, and dashing directives can be used in EdgeForm.
  • JoinForm can be used to specify how edge segments are joined.
  • EdgeForm applies to Polygon, Disk and Rectangle objects.
  • EdgeForm does not affect the rendering of Line objects.
  • In Graphics, the default is to draw no edges.
  • In Graphics3D, the default is to draw edges around every polygon.
  • No lines are ever drawn at edges formed by one polygon intersecting another.

Basic Examples  (1)

Specify the style of edges and faces:

Wolfram Language code: Graphics[{EdgeForm[{Thick, Blue}], FaceForm[Pink], Disk[]}]
Wolfram Language code: Graphics3D[{EdgeForm[{Thick, Blue}], FaceForm[Pink], Cuboid[]}, Boxed -> False]

Scope  (5)

Directive Specification  (4)

Edges with different thickness:

Wolfram Language code: Table[Graphics[{EdgeForm[Thickness[t]], LightGray, Rectangle[]}], {t, {Tiny, Small, Medium, Large}}]

Edges with different dashing:

Wolfram Language code: Table[Graphics[{EdgeForm[Dashing[d]], LightGray, Rectangle[]}], {d, {Tiny, Small, Medium, Large}}]

Edges with different color:

Wolfram Language code: Table[Graphics[{EdgeForm[c], LightGray, Rectangle[]}], {c, {Red, Green, Blue, Yellow}}]

Edges with several styles changed:

Wolfram Language code: Graphics[{EdgeForm[Directive[Thick, Dashed, Blue]], LightGray, Rectangle[]}]

Primitives Affected  (1)

Affected primitives:

Wolfram Language code: Graphics[{EdgeForm[{Blue, Thick}], LightGray, Rectangle[]}]
Wolfram Language code: Graphics[{EdgeForm[{Blue, Thick}], LightGray, Polygon[{{0, 0}, {1 / 2, 1}, {1, 0}}]}]
Wolfram Language code: Graphics3D[{EdgeForm[{Blue, Thick}], Cylinder[]}, Lighting -> "Neutral"]
Wolfram Language code: Graphics3D[{EdgeForm[{Blue, Thick}], Polygon[{{1, 0, 0}, {0, 0, 1}, {1, 1, 1}}]}, Lighting -> "Neutral"]
