Method Detail

• getColorAt

  public abstract Color getColorAt(int x,
                                   int y)

  Returns the color at the specified point, or null if the point is beyond the bounds of the palette or in an area that does not indicate a color

  Parameters:

  x - - an horizontal coordinate in the coordinate space of the palette

  y - - a vertical coordinate in the coordinate space of the palette

  Returns:

  - a color or null

• getNameAt

  public abstract String getNameAt(int x,
                                   int y)

  Returns a string description of the color at the point. May be a name or a set of RGB values, but should not be longer than 30 characters. Returns null if the position is outside the bounds of the palette or has no description associated with it. Generally getNameAt() should return null from the same coordinates that getColorAt() would.

  Parameters:

  x - an horizontal coordinate in the coordinate space of the palette

  y - a vertical coordinate in the coordinate space of the palette

  Returns:

  a string describing the color at this coordinate or null
