Constructor Detail

TTFTableLOCA

public TTFTableLOCA(TTFOffsetTableRecord dirEntry)

Constructor.

Parameters:

dirEntry - The parent table directory entry.

Method Detail

parse

public static TTFTableLOCA parse(TTFOffsetTableRecord dirEntry,
                                 RandomAccessInput raInput,
                                 boolean isLongFormat,
                                 int numberOfGlyphs,
                                 TTFTableHMTX hmtx)
                          throws IOException

Reads the "loca" table.

Parameters:

dirEntry - The parent table directory entry.

raInput - The input which is being parsed.

isLongFormat - Indicates whether the long format (true) or the short format (false) should be used. This information is derived from the "head" table.

numberOfGlyphs - The number of glyph entries to be parsed. This information is derived from the "maxp" table.

hmtx - The horizontal metrics ("hmtx") table.

Returns:

The parsed instance.

Throws:

IOException - For I/O Error.

getTableTag

public String getTableTag()

Return the 4-character name of this table, for example, "post" or "glyf".

Returns:

The name of this table.

lastOffset

public long lastOffset()

Returns the last offset value in the table. Note that this offset points to no glyph, but exists only for purposes of computing the size of the last valid item.

Returns:

The last offset value in the table.
