Method Detail
-
getOriginalGlyphIndex
int getOriginalGlyphIndex(int index)
Returns the original index of the glyph inside the (non-subset) font's glyph list. This index can be used to access the character width information, for example.- Parameters:
index
- the subset index (character selector) to access the glyph- Returns:
- the original index (or -1 if no glyph index is available for the subset index)
-
getUnicode
int getUnicode(int index)
Returns the Unicode value for a subset index (character selector). If there's no such Unicode value, the "NOT A CHARACTER" (0xFFFF) is returned.- Parameters:
index
- the subset index (character selector)- Returns:
- the Unicode value or "NOT A CHARACTER" (0xFFFF)
-
getUnicodeFromGID
char getUnicodeFromGID(int glyphIndex)
Gets the unicode character from the original font glyph index- Parameters:
glyphIndex
- The original glyph index of the character in the font- Returns:
- The character represented by the passed GID
-
getGIDFromChar
int getGIDFromChar(char ch)
Returns the glyph index from the original font from a character- Parameters:
ch
- The character- Returns:
- The glyph index in the original font.
-
mapChar
int mapChar(int glyphIndex, char unicode)
Maps a character to a character selector for a font subset. If the character isn't in the subset, yet, it is added and a new character selector returned. Otherwise, the already allocated character selector is returned from the existing map/subset.- Parameters:
glyphIndex
- the glyph index of the characterunicode
- the Unicode index of the character- Returns:
- the subset index
-
mapCodePoint
int mapCodePoint(int glyphIndex, int codePoint)
Maps a character to a character selector for a font subset. If the character isn't in the subset yet, it is added and a new character selector returned. Otherwise, the already allocated character selector is returned from the existing map/subset.- Parameters:
glyphIndex
- the glyph index of the charactercodePoint
- the Unicode index of the character- Returns:
- the subset index
-
getGlyphs
java.util.Map<java.lang.Integer,java.lang.Integer> getGlyphs()
Returns an unmodifiable Map of the font subset. It maps from glyph index to character selector (i.e. the subset index in this case).- Returns:
- Map Map<Integer, Integer> of the font subset
-
getChars
char[] getChars()
Returns a char array containing all Unicode characters that are in the subset.- Returns:
- a char array with all used Unicode characters
-
getNumberOfGlyphs
int getNumberOfGlyphs()
Returns the number of glyphs in the subset.- Returns:
- the number of glyphs in the subset
-
getGlyphIndices
java.util.BitSet getGlyphIndices()
Returns a BitSet with bits set for each available glyph index in the subset.- Returns:
- a BitSet indicating available glyph indices
-
getWidths
int[] getWidths()
Return the array of widths.This is used to get an array for inserting in an output format. It should not be used for lookup.
- Returns:
- an array of widths
