Method Detail

placePixels

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

Paints the pixels of a pixel iterator in a given colour at a given 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 the pixels of the RgbImage buffer.

Parameters:

xoff - X offset

yoff - Y offset

pixer - clipped pixel iterator, not null

color - painting colour
