## org.apache.fop.afp.fonts
Class AbstractOutlineFont

    java.lang.Object
      org.apache.fop.fonts.Typeface
          org.apache.fop.afp.fonts.AFPFont
              org.apache.fop.afp.fonts.AbstractOutlineFont

All Implemented Interfaces:
  FontMetrics

Direct Known Subclasses:
  DoubleByteFont, OutlineFont

    public abstract class AbstractOutlineFont

extends AFPFont

A font defined as a set of lines and curves as opposed to a bitmap font. An outline font can be scaled to any size and otherwise transformed more easily than a bitmap font, and with more attractive results.

Field Summary
`protected CharacterSet` | `charSet` The character set for this font

`eventListener, NOT_FOUND`

Constructor Summary
`AbstractOutlineFont(java.lang.String name, boolean embeddable, CharacterSet charSet, AFPEventProducer eventProducer)` Constructor for an outline font.

Method Summary
`int` | `getAscender(int size)` The ascender is the part of a lowercase letter that extends above the "x-height" (the height of the letter "x"), such as "d", "t", or "h".
`int` | `getCapHeight(int size)` Obtains the height of capital letters for the specified point size.
`CharacterSet` | `getCharacterSet()` Get the character set metrics.
`CharacterSet` | `getCharacterSet(int size)` Get the character set metrics.
`int` | `getDescender(int size)` The descender is the part of a lowercase letter that extends below the base line, such as "g", "j", or "p".
`java.lang.String` | `getEncodingName()` Get the encoding of the font.
`int` | `getUnderlinePosition(int size)` Returns the distance from the baseline to the center of the underline (negative value indicates below baseline).
`int` | `getUnderlineThickness(int size)` Returns the thickness of the underline.
`int` | `getXHeight(int size)` The "x-height" (the height of the letter "x").
`boolean` | `hasChar(char c)` Determines whether this font contains a particular character/glyph.
`char` | `mapChar(char c)` Map a Unicode character to a code point in the font.
