Method Detail

getEncodingTable

public CharTable getEncodingTable()

Description copied from class: FontTable

Returns a default CharTable to be used for normal text (not Symbol or Dingbats).

Specified by:

getEncodingTable in class FontTable

firstRequest

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

Description copied from class: FontTable

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.

Specified by:

firstRequest in class FontTable

Throws:

java.io.IOException

substituteFont

protected java.awt.Font substituteFont(java.awt.Font font)

removes any transformation and superscript, changes the names to PS font name

Specified by:

substituteFont in class FontTable

Parameters:

font -

Returns:

derived font

createFontReference

protected java.lang.String createFontReference(java.awt.Font font)

Uses the font name as a reference. Whitespace is stripped. The font style (italic/bold) is added as a suffix delimited by a dash. Uses normalize(java.util.Map)

Specified by:

createFontReference in class FontTable

normalize

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

Replaces TextAttribute.FAMILY by values of replaceFonts. Whitespace is family name stripped. When a font created using the result of this method the transformation would be: java.awt.Font[family=SansSerif,name=SansSerif,style=plain,size=30]
will result to:
java.awt.Font[family=SansSerif,name=Helvetica,style=plain,size=30]

Uses FontTable.normalize(java.util.Map) first.

Parameters:

attributes - with font name to change
