GrayLevel
GrayLevel
[
level
]
is a graphics directive which specifies the gray-level intensity with which objects that follow should be displayed.
GrayLevel
[
g
,
a
]
specifies opacity
a
.
MORE INFORMATION
The gray level must be a number between
0
and
1
.
»
0
represents black;
1
represents white.
On display devices with no native gray-level capability, dither patterns are typically used.
For 3D surfaces, explicit
GrayLevel
directives define surface colors; the final shading depends on lighting.
In
GrayLevel
[
g
,
a
]
,
a
is an "alpha channel" used to specify opacity.
GrayLevel
[
g
,
a
]
is equivalent to
{GrayLevel[
g
],
Opacity
[
a
]}
.
»
If no opacity has been specified,
GrayLevel
[
g
]
is equivalent to
GrayLevel
[
g
, 1]
.
Style
[
expr
, GrayLevel[
...
]]
specifies that
expr
should be displayed with the specified gray level.
