Constructor Detail

RGBBuffer

protected RGBBuffer()

Simple constructor to avoid memory allocations.

RGBBuffer

public RGBBuffer(int sizeX1,
         int sizeX2)

Creates a new 3-band buffer.

Parameters:

sizeX1 - The number of pixels on the X1-axis. This is the X-axis in the case of an XY-plane or XZ-plane. Otherwise it is the Z-axis — ZY-plane.

sizeX2 - The number of pixels on the X2-axis. This is the Y-axis in the case of an XY-plane or ZY-plane. Otherwise it is the Z-axis — XZ-plane.
