### 6.14. Bevel

#### 6.14.1. Overview

图 17.151. Applying example for the Bevel filter

From top to bottom, without bevel, “Chamfer” bevel, and “Bump” bevel.

This filter adds a bevel to the layer. This filter works best when there are transparent areas around a colored shape.

  These options are described in 第 2 节 “Common Features”.

Bevel Type

  You can choose between the following bevel types: Chamfer (the default) and Bump.

  Chamfer

    Simulates lighting of chamfered 3D-edges. Chamfered edges are sloped edges between two faces of an object.

  Bump

    Makes a 3D effect by adding an emboss effect on top of a blur.

Blend Mode

  Several blend modes can be chosen here to adjust the effect. The first one, None, is for when you intend to set a blend mode for the layer in GIMP.

Distance Map Setting

  Only available for Chamfer. There are three choices that each change the structure of the chamfer. Experiment to see what works best for your image.

  Euclidean

    The distance is a straight line.

  Manhattan

    The distance is the sum of the one-dimensional distances along the X and Y axes.

  Chebyshev

    The distance is the maximum of the one-dimensional distances along the X and Y axes.

Radius

  Only available for Bump. This determines the size of the softening for the bump.

Elevation

  This controls the elevation angle of the bevel.

Depth

  This controls the emboss depth; i.e. how deep and detailed the bevel will be.

Light Angle

  This controls the angle of the light source illuminating and shading the bevel.
