DensityStyle
public DensityStyle(DensityStyle.Channel channel)
Constructs a new style which plots in a given colour channel.- Parameters:
channel
- colour channel
-
-
Method Detail
-
setShader
public void setShader(Shader shader)
Sets the shader to use in indexed (non-RGB) mode. This should be an absolute shader.- Parameters:
shader
- shader
-
getShader
public Shader getShader()
Returns the shader to use in indexed (non-RGB) mode. This should be an absolute shader.- Returns:
- shader
-
levelBits
public int levelBits(byte level)
Defines how the style looks. This converts an unsigned byte value (that is a value in the range 0-255 got by doingvalue=0x000000ff&level
) to a bitmask which can be OR-ed with an existing integer to give a 32-type ARGB colour value.- Parameters:
level
- unsigned byte value- Returns:
- ORable bit mask for modifying a colour value
-
isRGB
protected abstract boolean isRGB()
Indicates whether the plotting is currently to be treated as three-channel RGB plotting or as single-channel intensity plotting.- Returns:
- true iff plotting is currently three-channel
