Method Details

setGammaTable

@Deprecated
public void setGammaTable(byte[][] gammaLut)

Deprecated.

Assigns a custom gamma table to the output

Parameters:

gammaLut - Two-dimensional array lookup of gamma curve for each precomputed brightness [0-255][0-255]

setGammaTable

public void setGammaTable(LXOutput.GammaTable gammaLut)

Assigns a custom gamma table to the output

Parameters:

gammaLut - Gamma lookup tables

setGammaDelegate

public void setGammaDelegate(LXOutput gammaDelegate)

setGroup

public void setGroup(LXOutputGroup output)

onParameterChanged

public void onParameterChanged(LXParameter p)

Description copied from class: LXComponent

Subclasses are free to override this if desired. It will automatically fire for any listenable parameter that is registered with this component.

Specified by:

onParameterChanged in interface LXParameterListener

Overrides:

onParameterChanged in class LXComponent

Parameters:

p - Parameter that has a value change

send

public LXOutput send(int[] colors)

Sends data to this output, applying throttle and color correction

Parameters:

colors - Array of color values

Returns:

this

send

public final LXOutput send(int[] colors,
 double brightness)

Sends data to this output at the pre-corrected brightness

Parameters:

colors - Color buffer

brightness - Brightness level from parent

Returns:

this

onSend

protected abstract void onSend(int[] colors,
 LXOutput.GammaTable glut,
 double brightness)

Subclasses implement this to send the data.

Parameters:

colors - Color values

glut - Look-up table for 0-255 brightness curves

brightness - Master brightness value

load

public void load(LX lx,
 JsonObject obj)

Description copied from class: LXComponent

Loads the LX component. Restores the ID of the component, as well as its internal and user-facing parameters. Any explicitly registered children will be automatically loaded, so long as they are direct descendants. Dynamic arrays will not be automatically loaded, this is left to subclasses to implement.

Specified by:

load in interface LXSerializable

Overrides:

load in class LXComponent

Parameters:

lx - LX instance

obj - Object to deserialize

log

public static final void log(String message)

error

public static final void error(String message)

error

public static final void error(Exception x,
 String message)
