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

144 * change visibiilty of given group

152 * Returns features at the specified aligned column on the given sequence.
153 * Non-positional features are not included. If the column has a gap, then
154 * enclosing features are included (but not contact features).
158 * aligned column position (1..)
