firstRequest

protected abstract void firstRequest(FontTable.Entry e,
                                     boolean embed,
                                     java.lang.String embedAs)
                              throws java.io.IOException

Called whenever a specific font is used for the first time. Subclasses may use this method to include the font instantly. This method may change the value of the reference by calling e.setReference(String) e.g. if it wants to substitute the font by a standard font that can be addressed under a name different from the generated one.

Throws:

java.io.IOException

createFontReference

protected abstract java.lang.String createFontReference(java.awt.Font f)

Creates a unique reference to address this font.

                                      java.lang.String embedAs)

Returns a name for this font that can be used in the document. A new name is generated if the font was not used yet. For different fontsizes the same name is returned.

normalize

public static void normalize(java.util.Map attributes)

creates a normalized attribute map, e.g. java.awt.Font[family=Dialog,name=dialog.bold,style=plain,size=20] becomes java.awt.Font[family=Dialog,name=Dialog,style=bold,size=20]
