• extendAuxRange

  public abstract void extendAuxRange​(Range range,
                                      BinList.Result binResult)

  Modifies the range of aux values found within a given surface.

  Parameters:

  range - range object to be modified

  binResult - tile bin contents

• renderBins

  public abstract void renderBins​(java.awt.Graphics g,
                                  BinList.Result binResult,
                                  Shader shader,
                                  Scaler scaler)

  Performs the rendering of a prepared bin list on a graphics surface.

  Parameters:

  g - graphics context

  binResult - histogram containing sky pixel values

  shader - colour shading

  scaler - value scaling

• createRenderer

  public static SkyTileRenderer createRenderer​(SkySurface surface,
                                               Rotation rotation,
                                               int viewLevel,
                                               double binFactor)

  Returns a SkyTileRenderer suitable for use on a given sky surface.

  Parameters:

  surface - sky surface

  rotation - view rotation state

  viewLevel - HEALPix level for view

  binFactor - factor by which all bin values should be multiplied

  Returns:

  tile renderer

• paintBins

  public static void paintBins​(java.awt.Graphics g,
                               BinList.Result binResult,
                               double binFactor,
                               SkySurface surface,
                               SkyPixer skyPixer,

                               Scaler scaler)

  Given a prepared data structure, paints the results it represents onto a graphics context appropriate for this drawing.

  Parameters:

  g - graphics context

  binResult - histogram containing sky pixel values

  binFactor - factor by which all bin values must be multiplied

  surface - plot surface

  skyPixer - maps sky positions to HEALPix indices

  shader - colour shading

  scaler - value scaling
