Method Detail

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)

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

Parameters:: surface - sky surface
Returns:: tile renderer

paintBins

public static void paintBins(java.awt.Graphics g,
                             BinList.Result binResult,
                             SkySurface surface,
                             SkyPixer skyPixer,
                             Shader shader,
                             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; surface - plot surface; skyPixer - maps sky positions to HEALPix indices; shader - colour shading; scaler - value scaling
