Method Detail

parse

public TrueTypeFont parse(RandomAccessRead randomAccessRead)
                   throws java.io.IOException

Parse a RandomAccessRead and return a TrueType font.

Parameters:

randomAccessRead - The RandomAccessREad to be read from. It will be closed before returning.

Returns:

A TrueType font.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

parseEmbedded

public TrueTypeFont parseEmbedded(java.io.InputStream inputStream)
                           throws java.io.IOException

Parse an input stream and return a TrueType font that is to be embedded.

Parameters:

inputStream - The TTF data stream to parse from. It will be closed before returning.

Returns:

A TrueType font.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

parseTableHeaders

public FontHeaders parseTableHeaders(RandomAccessRead randomAccessRead)
                              throws java.io.IOException

Parse a RandomAccessRead and return a TrueType font.

Parameters:

randomAccessRead - The RandomAccessREad to be read from. It will be closed before returning.

Returns:

TrueType font headers.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

createFontWithTables

private TrueTypeFont createFontWithTables(TTFDataStream raf)
                                   throws java.io.IOException

Parse a file and get a true type font.

Parameters:

raf - The TTF file.

Returns:

A TrueType font.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

parse

TrueTypeFont parse(TTFDataStream raf)
            throws java.io.IOException

Throws:

java.io.IOException

newFont

TrueTypeFont newFont(TTFDataStream raf)

parseTables

private void parseTables(TrueTypeFont font)
                  throws java.io.IOException

Parse all tables and check if all needed tables are present.

Parameters:

font - the TrueTypeFont instance holding the parsed data.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

parseTableHeaders

FontHeaders parseTableHeaders(TTFDataStream raf)
                       throws java.io.IOException

Based on #parseTables(). Parse all table headers and check if all needed tables are present. This method can be optimized further by skipping unused portions inside each individual table parser

Parameters:

font - the TrueTypeFont instance holding the parsed data.

Throws:

java.io.IOException - If there is an error parsing the TrueType font.

allowCFF

protected boolean allowCFF()

readTableDirectory

private TTFTable readTableDirectory(TTFDataStream raf)
                             throws java.io.IOException

Throws:

java.io.IOException

readTable

protected TTFTable readTable(java.lang.String tag)
