Wolfram: Graphics Directive

What is Graphics Directive

Graphics Directives are things like color, thickness. They control the style and rendering of Graphics Primitive .

Here are commonly used graphics directives:

• Red Green Blue Hue GrayLevel etc.
• Opacity
• PointSize
• Thickness
• Dashed
• more

• Wolfram: Opacity (Transparency)

• EdgeForm FaceForm
• AmbientLight PointLight DirectionalLight SpotLight
• more

How to Apply Graphics Directive

Put directives in a list, preceding primitives. They have effect on the subsequent graphics primitives. e.g.

{Red, Thick, Circle[]}

Example

Graphics[{Red, Circle[ ]} , Axes -> True ]

Graphics[{Red, Circle[ ], Line[{{0,0},{1,1}}] }, Axes -> True ]

Example

Graphics[{Red, Line[{{0,0},{1,1}}], Blue, Thick, Line[{{0,0},{1,2}}] }, Axes -> True ]

Grouping Graphics Directives

you can group several graphics directives as a single entity.

Directive. Group Graphics Directives

Directive

Group several graphics directive into one. e.g.

Directive[Red, Thick] or Directive[{Red, Thick}]

• Directive

Graphics[{
Directive[Red, Thick],
Line[{{0,0},{1,2}}]
},
Axes -> True ]

Style. Group Directives and Primitives

Style[prim, directive1, directive1, etc]

example

Style[Circle[], Red, Thick]

• Style
