## org.biojava.bio.gui.sequence
Interface PairwiseRenderContext

All Superinterfaces:
  SequenceRenderContext, SwingConstants

All Known Implementing Classes:
  PairwiseSequencePanel, SubPairwiseRenderContext

    public interface PairwiseRenderContext

extends SequenceRenderContext

`PairwiseRenderContext` encapsulates information required for the rendering of a pair of sequences. No assumption is made as to whether the sequences are to be rendered in different directions (as in a dotplot) or in the same direction; this is left to the implementation. The leading and trailing borders refer to the primary sequence only.

Method Detail

### getSecondaryDirection

    int getSecondaryDirection()

  `getSecondaryDirection` returns the direction in which the secondary sequence is rendered. This may be either HORIZONTAL or VERTICAL.

  Returns:
    an `int`.

### getSecondarySymbols

    SymbolList getSecondarySymbols()

  `getSecondarySymbols` returns the symbols of the secondary sequence.

  Returns:
    a `SymbolList`.

### getSecondaryFeatures

    FeatureHolder getSecondaryFeatures()

  `getSecondaryFeatures` returns the features on the secondary sequence.

  Returns:
    a `FeatureHolder`.

### getSecondaryRange

    RangeLocation getSecondaryRange()

  `getSecondaryRange` returns the range of the secondary sequence currently rendered.

  Returns:
    a `RangeLocation`.

### secondarySequenceToGraphics

    double secondarySequenceToGraphics(int sequencePos)

  `secondarySequenceToGraphics` converts a sequence coordinate on the secondary sequence to a graphical position.

  Parameters:
    `sequencePos` - an `int`.
  Returns:
    a `double`.

### graphicsToSecondarySequence

    int graphicsToSecondarySequence(double graphicsPos)

  `graphicsToSecondarySequence` converts a graphical position to a sequence coordinate on the secondary sequence.

  Parameters:
    `graphicsPos` - a `double`.
  Returns:
    an `int`.

### graphicsToSecondarySequence

    int graphicsToSecondarySequence(Point point)

  `graphicsToSecondarySequence` converts a graphical position to a secondary sequence index.

  Parameters:
    `point` - a `Point`.
  Returns:
    an `int`.
