Method Details

getDataBuffer

protected abstract byte[] getDataBuffer()

Subclasses should provide a handle to a raw byte buffer

Returns:

Raw byte buffer for output data

getDataBufferOffset

protected abstract int getDataBufferOffset()

Offset into raw byte buffer where color data is written

Returns:

Offset into raw byte buffer for color data

updateDataBuffer

protected LXBufferOutput updateDataBuffer(int[] colors,
 LXOutput.GammaTable glut,
 double brightness)

Helper for subclasses to copy a list of points into the data buffer at a specified offset. For many subclasses which wrap RGB buffers, onSend() will be a simple call to this method with the right parameters.

Parameters:

colors - Array of color values

glut - Look-up tables for gamma-corrected brightness values by brightness

brightness - Master brightness

Returns:
