Default constructor - used when there is no palette specified

 public PaletteRecord(Record t) 
{
           
    super(t);
    initialized = false;
    dirty = false;
    read = true;
}

Constructor

Parameters:

t - the raw bytes

 public RGB getColourRGB(Colour c) 
{
    // Only colours on the standard palette with values 8-64 are acceptable
    int pos = c.getValue() - 8;
    if (pos <  0 || pos  >= numColours)
    {
      return c.getDefaultRGB();
    }
    if (!initialized)
    {
      initialize();
    }
    return rgbColours[pos];
}

Gets the colour RGB from the palette

 public byte[] getData() 
{
    // Palette was read in, but has not been changed
    if (read && !dirty)
    {
      return getRecord().getData();
    }
    byte[] data = new byte[numColours * 4 + 2];
    int pos = 0;
    // Set the number of records
    IntegerHelper.getTwoBytes(numColours, data, pos);
    // Set the rgb content
    for (int i = 0; i <  numColours; i++)
    {
      pos = i * 4 + 2;
      data[pos]     = (byte) rgbColours[i].getRed();
      data[pos + 1] = (byte) rgbColours[i].getGreen();
      data[pos + 2] = (byte) rgbColours[i].getBlue();
    }
    return data;
}

Accessor for the binary data - used when copying

 public boolean isDirty() 
{
    return dirty;
}

Accessor for the dirty flag, which indicates if this palette has been modified

 public  void setColourRGB(Colour c,
    int r,
    int g,
    int b) 
{
    // Only colours on the standard palette with values 8-64 are acceptable
    int pos = c.getValue() - 8;
    if (pos <  0 || pos  >= numColours)
    {
      return;
    }
    if (!initialized)
    {
      initialize();
    }
    // Force the colours into the range 0-255
    r = setValueRange(r, 0, 0xff);
    g = setValueRange(g, 0, 0xff);
    b = setValueRange(b, 0, 0xff);
    rgbColours[pos] = new RGB(r, g, b);
    // Indicate that the palette has been modified
    dirty = true;
}

Sets the RGB value for the specified colour for this workbook
