Interface Positionable

All Known Implementing Classes:
  Font, LazyFont, MultiByteFont

    public interface Positionable

Optional interface which indicates that glyph positioning is supported and, if supported, can perform positioning.

This work was originally authored by Glenn Adams (gadams@apache.org).

Method Summary
`int[][]` `performPositioning(java.lang.CharSequence cs, java.lang.String script, java.lang.String language)` Perform glyph positioning using an implied font size.
`int[][]` `performPositioning(java.lang.CharSequence cs, java.lang.String script, java.lang.String language, int fontSize)` Perform glyph positioning.
`boolean` `performsPositioning()` Determines if font performs glyph positioning.

Method Detail

### performsPositioning

    boolean performsPositioning()

  Determines if font performs glyph positioning.

  Returns:
    true if performs positioning

### performPositioning

    int[][] performPositioning(java.lang.CharSequence cs,
                               java.lang.String script,
                               java.lang.String language,
                               int fontSize)

  Perform glyph positioning.

  Parameters:
    `cs` - character sequence to map to position offsets (advancement adjustments)
    `script` - a script identifier
    `language` - a language identifier
    `fontSize` - font size
  Returns:
    array (sequence) of 4-tuples of placement [PX,PY] and advance [AX,AY] adjustments, in that order, with one 4-tuple for each element of glyph sequence, or null if no non-zero adjustment applies

### performPositioning

    int[][] performPositioning(java.lang.CharSequence cs,
                               java.lang.String script,
                               java.lang.String language)

  Perform glyph positioning using an implied font size.

  Parameters:
    `cs` - character sequence to map to position offsets (advancement adjustments)
    `script` - a script identifier
    `language` - a language identifier
  Returns:
    array (sequence) of 4-tuples of placement [PX,PY] and advance [AX,AY] adjustments, in that order, with one 4-tuple for each element of glyph sequence, or null if no non-zero adjustment applies
