Class GlyphPaper

Method Details

• glyphPixels

  public abstract void glyphPixels(Pixer pixer)

  For each glyph painted on this paper, a pixer will be passed to this method that iterates over all the pixels within this paper's bounds. The supplied pixer will not contain any pixels outside the plot bounds.

  Parameters:

  pixer - pixel iterator

• getPaperType

  public GlyphPaper.GlyphPaperType getPaperType()

  Returns a partial PaperType implementation to use with this object. The returned value is private to this paper instance.

  Specified by:

  getPaperType in interface Paper

  Returns:

  paper type

• canMerge

  public boolean canMerge()

  Returns false. Use of this paper type is expected to be parallel already, so parallelising paint operations is not necessary.

  Specified by:

  canMerge in interface Paper

  Returns:

  true iff sheet split/merge is supported

• createSheet

  public Paper createSheet()

  Description copied from interface: Paper

  Returns a blank Paper instance that is compatible with this one. That essentially means an instance like this but with nothing yet painted on it.

  May only be invoked if Paper.canMerge() returns true.

  Specified by:

  createSheet in interface Paper

  Returns:

  new compatible paper instance

• mergeSheet

  public void mergeSheet(Paper other)

  Description copied from interface: Paper

  Merges the contents of a compatible paper instance with this one. The supplied sheet is assumed to have been created by an earlier invocation of Paper.createSheet() on this instance or on a compatible instance.

  The effect is as if everything that has been painted to the supplied sheet will now be painted on this one.

  This is intended for use in parallelising painting of a large number of 2D or 3D Glyphs. Merging papers on which Decals have been placed may or may not work.

  May only be invoked if Paper.canMerge() returns true.

  Specified by:

  mergeSheet in interface Paper

  Parameters:

  other - compatible paper instance
