RoundingRadius

RoundingRadius

is an option for Rectangle, Framed and related functions that specifies the radius of the circle to use in rendering rounded corners.

Details

  • The radius specification can have the following forms:
  • rapply radius r to all corners
    {rx,ry}specify different rounding radii in the and directions
    {spec,rules}use rules to override the default specification spec for specific corners
  • rules can be used to specify different radii for specific corners. A rule specification can be of the form {sidex,sidey}spec, where sidex can be Left or Right, and sidey can be Top or Bottom. A rule can also be specified as sidespec, which will set the radii for both corners of the given side.
  • In graphics, the radius can be specified as follows:
  • rdistance r in ordinary graphics coordinates
    Scaled[s], ImageScaled[s]fraction s of the size of the graphic
    Offset[d]d printer's points
  • For constructs such as Framed, RoundingRadius->r always specifies the radius in absolute printer's points.
  • RoundingRadius->0 specifies non-rounded corners.
  • The effective radius used for any corner is limited to the half-length of each adjacent side.

Basic Examples  (2)

A round rectangle:

Wolfram Language code: Graphics[Rectangle[{0, 0}, {2, 1}, RoundingRadius -> 0.3]]

An object with rounded frame:

Wolfram Language code: Framed[1 / x + y + z, RoundingRadius -> 10]

Scope  (10)

Specify round corners:

Wolfram Language code: Table[Graphics[Rectangle[{0, 0}, {2, 1}, RoundingRadius -> m], PlotLabel -> m], {m, {0, .1, 2, .5}}]
Wolfram Language code: Table[Framed[Graphics3D[Sphere[{0, 0, 0}], ImageSize -> Tiny, PlotLabel -> m], RoundingRadius -> m], {m, {0, 10, 20, 50}}]

Differently styled round rectangle edges:

Wolfram Language code: {Graphics[{Pink, Rectangle[{0, 0}, {1, 1}, RoundingRadius -> 0.3]}], Graphics[{EdgeForm[Thick], Pink, Rectangle[{0, 0}, {1, 1}, RoundingRadius -> 0.3]}], Graphics[{EdgeForm[Dashed], Pink, Rectangle[{0, 0}, {1, 1}, RoundingRadius -> 0.3]}], Graphics[{EdgeForm[Directive[Thick, Dashed, Blue]], Pink, Rectangle[{0, 0}, {1, 1}, RoundingRadius -> 0.3]}]}

Specify different rounding radii in the and directions:

Wolfram Language code: Graphics[Rectangle[{0, 0}, {1, 1}, RoundingRadius -> {0.3, 0.5}]]

Specify different rounding values for different corners:

Wolfram Language code: Graphics[Rectangle[{0, 0}, {1, 1}, RoundingRadius -> {0, {Left, Top} -> .1}]]
Wolfram Language code: Framed["abc", RoundingRadius -> {0, {Left, Top} -> 15, {Right, Bottom} -> 5}]

Override both corners on the left side:

Wolfram Language code: Graphics[Rectangle[{0, 0}, {1, 1}, RoundingRadius -> {0, Left -> .1}]]
Wolfram Language code: Framed["abc", RoundingRadius -> {0, Left -> 10}]

The effective radius used for any corner is limited to the half-length of each adjacent side:

Wolfram Language code: Graphics[Rectangle[{0, 0}, {1, 1}, RoundingRadius -> 1]]

For Framed, RoundingRadius->r always specifies the radius in absolute printer's points:

Wolfram Language code: Framed[Graphics3D[Sphere[{0, 0, 0}], ImageSize -> Tiny], RoundingRadius -> {50, 10}]

Use Scaled coordinates and Scaled rounding radius:

Wolfram Language code: Graphics[Rectangle[Scaled[{0, .4}], Scaled[{1, .6}], RoundingRadius -> Scaled[.1]], Frame -> True, PlotRange -> {{0, 10}, {0, 10}}]

Use ImageScaled coordinates and ImageScaled rounding radius:

Wolfram Language code: Graphics[Rectangle[ImageScaled[{0, .4}], ImageScaled[{1, .6}], RoundingRadius -> ImageScaled[.1]], Frame -> True, PlotRange -> {{0, 10}, {0, 10}}]

Use Offset coordinates and Offset rounding radius:

Wolfram Language code: Graphics[Rectangle[Offset[{10, 20}, {0, 0}], Offset[{-10, -20}, {1, 1}], RoundingRadius -> Offset[{50, 10}]], Frame -> True]
