Class FontIncluder

java.lang.Object
  org.freehep.graphicsio.font.FontIncluder

Direct Known Subclasses:

FontEmbedder, PDFFontIncluder

public abstract class FontIncluder

extends Object

Instances of this class write the information into documents (ps or pdf) that is necessary in order to include or embed fonts. In order to guarantee a time-invariant interface the main methods to implement by subclasses includeFont takes no arguments. All necessary data should be available by getter methods which can easily be added.
The abstract methods are called in the following order:

• openIncludeFont
• writeEncoding
• closeIncludeFont
