Class Kern

java.lang.Object
  extended by org.apache.batik.gvt.font.Kern

public class Kern
extends Object

The Kern class describes an entry in the "kerning table". It provides a kerning value to be used when laying out characters side by side. It may be used for either horizontal or vertical kerning.


Constructor Summary
Kern(int[] firstGlyphCodes, int[] secondGlyphCodes, UnicodeRange[] firstUnicodeRanges, UnicodeRange[] secondUnicodeRanges, float adjustValue)
          Creates a Kern object with the given glyph arrays and kerning value.
 
Method Summary
 float getAdjustValue()
          Returns the kerning adjustment value for this kerning entry (a positive value means the space between characters should decrease).
 boolean matchesFirstGlyph(int glyphCode, char glyphUnicode)
          Returns true if the specified glyph is one of the glyphs considered as first by this kerning entry.
 boolean matchesFirstGlyph(int glyphCode, String glyphUnicode)
          Returns true if the specified glyph is one of the glyphs considered as first by this kerning entry.
 boolean matchesSecondGlyph(int glyphCode, char glyphUnicode)
          Returns true if the specified glyph is one of the glyphs considered as second by this kerning entry.
 boolean matchesSecondGlyph(int glyphCode, String glyphUnicode)
          Returns true if the specified glyph is one of the glyphs considered as second by this kerning entry.

Constructor Detail

Kern

public Kern(int[] firstGlyphCodes,
            int[] secondGlyphCodes,
            UnicodeRange[] firstUnicodeRanges,
            UnicodeRange[] secondUnicodeRanges,
            float adjustValue)
Creates a Kern object with the given glyph arrays and kerning value. The first and second sets of glyphs for this kerning entry consist of the union of glyphs in the glyph code arrays and the unicode ranges.

Parameters:
firstGlyphCodes - An array of glyph codes that are part of the first set of glyphs in this kerning entry.
secondGlyphCodes - An array of glyph codes that are part of the second set of glyphs in this kerning entry.
firstUnicodeRanges - An array of unicode ranges that are part of the first set of glyphs in this kerning entry.
secondUnicodeRanges - An array of unicode ranges that are part of the second set of glyphs in this kerning entry.
adjustValue - The kerning adjustment (positive value means the space between glyphs should decrease).
Method Detail

matchesFirstGlyph

public boolean matchesFirstGlyph(int glyphCode,
                                 String glyphUnicode)

Parameters:
glyphCode - The id of the glyph to test.
glyphUnicode - The unicode value of the glyph to test.
Returns:
True if this glyph is in the list of first glyphs for the kerning entry

matchesSecondGlyph

public boolean matchesSecondGlyph(int glyphCode,
                                  String glyphUnicode)

Parameters:
glyphCode - The id of the glyph to test.
glyphUnicode - The unicode value of the glyph to test.
Returns:
True if this glyph is in the list of second glyphs for the kerning entry

getAdjustValue

public float getAdjustValue()
Returns the kerning adjustment value for this kerning entry (a positive value means the space between characters should decrease).

Returns:
