Method Detail

glyphId

public int glyphId(int character)

Description copied from class: CMap

Gets the glyph id for the character code provided. The character code provided must be in the encoding used by the cmap table.

Specified by:

glyphId in class CMap

Parameters:

character - character value using the encoding of the cmap table

Returns:

glyph id for the character code

retrieveGlyphId

public int retrieveGlyphId(int segment,
                           int startCode,
                           int character)

Lower level glyph code retrieval that requires processing the Format 4 segments to use.

Parameters:

segment - the cmap segment

startCode - the start code for the segment

character - the character to be looked up

Returns:

the glyph id for the character; CMapTable.NOTDEF if not found

getSegCount

public int getSegCount()

Gets the count of the number of segments in this cmap.

Returns:

the number of segments

startCode

public int startCode(int segment)

Gets the start code for a segment.

Parameters:

segment - the segment in the look up table

Returns:

the start code for the segment

endCode

public int endCode(int segment)

Gets the end code for a segment.

Parameters:

segment - the segment in the look up table

Returns:

the end code for the segment

idDelta

public int idDelta(int segment)

Gets the id delta for a segment.

Parameters:

segment - the segment in the look up table

Returns:

the id delta for the segment

idRangeOffset

public int idRangeOffset(int segment)

Gets the id range offset for a segment.

Parameters:

segment - the segment in the look up table

Returns:

the id range offset for the segment

idRangeOffsetLocation

public int idRangeOffsetLocation(int segment)

Get the location of the id range offset for a segment.

Parameters:

segment - the segment in the look up table

Returns:

the location of the id range offset for the segment

language

public int language()

Description copied from class: CMap

Gets the language of the cmap. Note on the language field in 'cmap' subtables: The language field must be set to zero for all cmap subtables whose platform IDs are other than Macintosh (platform ID 1). For cmap subtables whose platform IDs are Macintosh, set this field to the Macintosh language ID of the cmap subtable plus one, or to zero if the cmap subtable is not language-specific. For example, a Mac OS Turkish cmap subtable must set this field to 18, since the Macintosh language ID for Turkish is 17. A Mac OS Roman cmap subtable must set this field to 0, since Mac OS Roman is not a language-specific encoding.

Specified by:

language in class CMap

Returns:

the language id

iterator

public java.util.Iterator<java.lang.Integer> iterator()
