32 * Abstract feature renderer interface
37 public interface FeatureRenderer
41 * Computes the feature colour for a given sequence and column position,
42 * taking into account sequence feature locations, feature colour schemes,
43 * render ordering, feature and feature group visibility, and transparency.
45 * The graphics argument should be provided if transparency is applied
46 * (getTransparency() < 1). With feature transparency, visible features are
47 * written to the graphics context and the composite colour may be read off
48 * from it. In this case, the returned feature colour is not the composite
49 * colour but that of the last feature drawn.
51 * If no transparency applies, then the graphics argument may be null, and the
52 * returned colour is the one that would be drawn for the feature.
54 * Returns null if there is no visible feature at the position.
56 * This is provided to support rendering of feature colours other than on the
57 * sequence alignment, including by structure viewers and the overview window.
58 * Note this method takes no account of whether the sequence or column is
63 * aligned column position (1..)
