Method Detail

placePixels

protected abstract void placePixels(int xoff,
                                    int yoff,
                                    double dz,
                                    Pixer pixer,
                                    Color color)

Paints the pixels of a pixel iterator in a given colour at a given 3d position. Subclasses implement this method to perform the actual pixel compositing. The supplied pixer will already have been clipped, so implementations don't need to worry about checking the positions are within the bounds of this paper. Implementations can (and usually should) use the RgbPaperType.RgbPaper.getPixelIndex(int, int, uk.ac.starlink.ttools.plot2.Pixer) method to address pixels of the RgbImage buffer.

Parameters:

xoff - X graphics offset

yoff - Y graphics offset

dz - depth coordinate, lower value means closer to viewer

pixer - clipped pixel iterator, not null

color - painting colour
