public AWTColorbarImageGenerator(ColorMapper mapper,
                                 ITickProvider provider,
                                 ITickRenderer renderer)

Method Detail

toImage

public BufferedImage toImage(int width,
                             int height)

Specified by:

toImage in interface AWTImageGenerator

toImage

public BufferedImage toImage(int width,
                             int height,
                             int barWidth)

Renders the AWTColorbarImageGenerator to an image.

drawBarContour

public void drawBarContour(int height,
                           int barWidth,
                           Graphics2D graphic)

Draw a bar border. Keep a space of half text height between the top of image and top of colorbar (same for bottom) to ensure a tick label at max or min position would not be cut at image border. The text size is given by AWTAbstractImageGenerator.setFont(org.jzy3d.painters.Font)

Parameters:

height -

barWidth -

graphic -

drawBarColors

Draw a bar content using the provided color mapper.

Parameters:

height -

barWidth -

graphic -

drawTextAnnotations

public void drawTextAnnotations(int height,
                                int barWidth,
                                Graphics2D graphic)

getPixelScale

public Coord2d getPixelScale()

setPixelScale

public void setPixelScale(Coord2d pixelScale)

getPreferedWidth

public int getPreferedWidth(IPainter painter)

Compute the optimal image width to contain the text as defined by the tick provided and renderer.

getPreferedWidth
