Class ClasspathFontPeer
java.lang.Objectgnu.java.awt.peer.ClasspathFontPeer
- All Implemented Interfaces:
- java.awt.peer.FontPeer
- public abstract class ClasspathFontPeer
- extends java.lang.Object
- implements java.awt.peer.FontPeer
- extends java.lang.Object
A peer for fonts that are used inside Classpath. The purpose of this interface is to abstract from platform-specific font handling in the Classpath implementation of java.awt.Font and related classes.
State kept by the peer: a peer is generated for each Font
object in the default implementation. If you wish to share peers between
fonts, you will need to subclass both ClasspathFontPeer and
ClasspathToolKit.
Thread Safety: Methods of this interface may be called
from arbitrary threads at any time. Implementations of the
ClasspathFontPeer interface are required to perform
the necessary synchronization.

getGlyphName
public abstract java.lang.String getGlyphName(java.awt.Font font, int glyphIndex)
- Returns a name for the specified glyph. This is useful for
generating PostScript or PDF files that embed some glyphs of a
font. If the implementation follows glyph naming conventions
specified by Adobe, search engines can extract the original text
from the generated PostScript and PDF files.
This method is currently not used by GNU Classpath. However, it would be very useful for someone wishing to write a good PostScript or PDF stream provider for the
javax.printpackage.Names are not unique: Under some rare circumstances, the same name can be returned for different glyphs. It is therefore recommended that printer drivers check whether the same name has already been returned for antoher glyph, and make the name unique by adding the string ".alt" followed by the glyph index.
This situation would occur for an OpenType or TrueType font that has a
posttable of format 3 and provides a mapping from glyph IDs to Unicode sequences through aZapftable. If the same sequence of Unicode codepoints leads to different glyphs (depending on contextual position, for example, or on typographic sophistication level), the same name would get synthesized for those glyphs. To avoid this, the font peer would have to go through the names of all glyphs, which would make this operation very inefficient with large fonts.
