Description copied from class: FontEmbedder

Writes the character widths to the file.

Specified by:

writeWidths in class FontEmbedder

Throws:

IOException

writeEncoding

protected void writeEncoding(CharTable t)
                      throws IOException

Description copied from class: FontIncluder

Writes the encoding table to the file.

openIncludeFont

protected void openIncludeFont()
                        throws IOException

Description copied from class: FontIncluder

Writes the given information about the font into the file. When this method is called all getXXX() are guaranteed to return reasonable values.

Specified by:

openIncludeFont in class FontIncluder

Throws:

IOException

closeIncludeFont

protected void closeIncludeFont()

Description copied from class: FontIncluder

Does nothing, but can be implemented by subclasses if necessary.

Overrides:

closeIncludeFont in class FontIncluder

openGlyphs

protected void openGlyphs()
                   throws IOException

Description copied from class: FontEmbedder

Called before the glyph loop starts. Does nothing by default but can be implemented.

Overrides:

openGlyphs in class FontEmbedder

Throws:

IOException

closeGlyphs

protected void closeGlyphs()
                    throws IOException

Description copied from class: FontEmbedder

Called after the glyph loop ends. Does nothing by default but can be implemented.

Overrides:

closeGlyphs in class FontEmbedder

Throws:

IOException

closeEmbedFont

protected void writeGlyph(String characterName,
                          Shape glyph,
                          GlyphMetrics glyphMetrics)
                   throws IOException

Description copied from class: FontEmbedder

Writes a single glyph to the file. A null value for glyphMetrics indicates the undefined character. In this case the value of unicodeName equals the value of NOTDEF (=.notdef).

writeGlyph in class FontEmbedder

Parameters:

characterName - the character's name according to the unicode standard

glyph - the shape that represents this glyph

glyphMetrics - the metrics of this glyph

Throws:

IOException

getAsciiLength

public int getAsciiLength()

Returns the length of the ascii portion of the output.

getEncryptedLength

public int getEncryptedLength()

Returns the length of the encrypted portion of the output.
