DropShadowing

DropShadowing[]

is a twodimensional directive specifying that graphics objects are to be drawn with an additional blurred offset image.

DropShadowing[{dx,dy}]

uses an absolute offset {dx,dy}.

DropShadowing[{dx,dy},r]

applies a blur effect with radius r.

DropShadowing[{dx,dy},r,col]

uses the specified color col for the blurred offset image.

Apply a drop shadow effect to text:

Plot curves with shadows:

Show a map of the US with drop shadow:

Scope  (15)

Basic Uses  (7)

Apply drop shadow to graphics primitives:

Apply drop shadow to Text:

Apply drop shadow to a plot:

Apply drop shadow to a chart:

Style a geometric region:

Show a schematic outline map:

Summary box:

Specifications  (8)

DropShadowEffect with no arguments draws a translucent shadow to the bottom left of the object:

Specify the offset of the shadow relative to the original object:

Use a custom shadow blur radius:

The shadow color is set to GrayLevel[0,1/3] by default:

Set the shadow color explicitly:

Set the color to Inherited to use the FaceForm color of the original object with half opacity:

DropShadowEffect works with shadow colors with opacity:

Use the FaceForm color of the original object with a custom opacity:

Set the blur radius while using the default values for offset and color:

This is equivalent to only giving the blur radius:

Set the shadow color while using the default values for offset and blur:

This is equivalent to only giving the color:

The shadow offset and blur radius are specified in printer's points by default:

Use an ImageScaled offset and radius:

Applications  (11)

Basic Applications  (1)

Show the shadow offset and blur radius:

Offset the shadow to the right:

Blur the shadow using various radii:

Offset to the lower left with a large blur radius:

Shadow Effects  (3)

Simulate 3D depth in a 2D graphic:

Larger values for the offset and blur radius correspond to greater depth:

Create a glow effect by using no offset with a large blur radius:

Approximate a thin outline by using multiple drop shadows:

Graphics  (3)

Apply drop shadow to graphics primitives:

Apply drop shadow to Text:

Apply drop shadow to a GraphicsComplex:

Visualization  (4)

Plot curves with drop shadows:

Style bar charts:

Style vector plots:

Style parametric plots:

Properties & Relations  (2)

Drop shadow effects can also be produced using image processing functions:

The equivalent effect using DropShadowing:

Graphics primitives can be duplicated and offset using Offset to simulate an exact shadow:

Possible Issues  (1)

Drop shadows are drawn in the order in which their corresponding objects are defined in Graphics:

Interactive Examples  (1)

Adjust the drop shadow offset, blur radius and color on a plot:

Neat Examples  (2)

Add depth to overlapping polygons:
