## org.faceless.pdf2
Class Type1Font

    java.lang.Object
      org.faceless.pdf2.PDFFont
          org.faceless.pdf2.Type1Font

All Implemented Interfaces:
  Cloneable

    public final class Type1Font

extends PDFFont

Create a new PostScript Type 1 font. This class of font is commonly used on UNIX systems. The standard 14 fonts are a special class of Type 1 font.

Type 1 fonts give each character shape, or "glyph", a name, in the same way the PDF documents refer to glyphs by name (hardly surprising really, seeing as both Type 1 fonts and PDF documents are defined by Adobe). Because text written to the PDF via this library is specified in Unicode, Type 1 fonts need a "mapping" from Unicode character to Glyph name.

For many fonts this isn't a problem. Font's based on the latin character set (more specifically, fonts implementing a subset of the Adobe Standard Glyph List) already have their mapping defined. If the glyphs in the font have names taken from this list, no further thought needs to be given to this issue.

If not, it is necessary for the developer to supply a mapping between Unicode character and Glyph name. This is supplied as a `Map` where either the key is a `String` representing the name and the value is a `Character`, or the inverse (the key is a `Character` and the value a `String`). The former ordering is more useful for most Type 1 fonts, the latter was the only format accepted by this class prior to version 2.7.6.

Since:
  1.0

Field Detail

### AGL

    public static final Map AGL

  This `Map` represents the Adobe Standard Glyph Lists. Some fonts which claim to be encoded using the Adobe Standard Glyph mapping deviate from the list slightly. Using this Map you can easily create a slight variation on the standard mapping to pass into the Type 1 constructor. For example, lets say your font has a glyph called "hyphenminus" instead of the standard name "hyphen". You could create the font like so:

       Map mymap = new HashMap(Type1Font.AGL);
       mymap.put("hyphenminus", new Character('-'));
       PDFFont myfont = new Type1Font(afmfile, pfbfile, mymap);

  Since:
    2.1

Constructor Detail

### Type1Font

    public Type1Font(InputStream afm,
                     InputStream pfb)
              throws IOException

  Create a new Type 1 font, using the standard Adobe mapping from unicode to glyph name.

  Parameters:
    `afm` - The `.afm` (Adobe Font Metrics) file specifying the metrics for this font
    `pfb` - The `.pfb` or `.pfa` file containing the glyph shapes to be embedded in the PDF. If the font is not to be embedded, this should be null.
  Throws:
    `IOException` - If the `.afm` or .pfb InputStream can't be read or parsed

### Type1Font

    public Type1Font(InputStream afm,
                     InputStream pfb,
                     Map mapping)
              throws IOException

  Create a new Type 1 font, using a user defined mapping from unicode to glyph name. The font can be embedded, which ensures that your viewers will see exactly the font you specified, at the cost of increasing the file size. If a font is not embedded and the viewer does not have the same font installed, the viewing software will substitute an "appropriate" font.

  Parameters:
    `afm` - The `.afm` (Adobe Font Metrics) file specifying the metrics for this font
    `pfb` - The `.pfb` or `.pfa` file containing the glyph shapes to be embedded in the PDF. If the font is not to be embedded, this should be null.
    `mapping` - The mapping between unicode and glyph name, as described inu the class header above. A value of `null` uses the Adobe Standard Glyph List
  Throws:
    `IOException` - If the `.afm` or .pfb file can't be read or parsed

Method Detail

### getDefaultLeading

    public float getDefaultLeading()

  Description copied from class: `PDFFont`

  Get the default leading for this font - the preferred distance between two successive baselines of text. Values are a ratio of the font size, and are typically between 1 and 1.3

  Note that the values of the different spacing-between-lines methods have changed - in versions 1.0.4 and earlier this routine normally returned 1 and the spacing was set by the `PDFStyle.setTextLineSpacing(float)` method. Since 1.1, the values for these two methods are effectively reversed. See the relevant method comments in the `PDFStyle` class for more information.

  Specified by:
    `getDefaultLeading` in class `PDFFont`

### getSubscriptPosition

    public float getSubscriptPosition()

  Description copied from class: `PDFFont`

  Get the recommended position of a sub-script version of this font, as a proportion of the sub-scripted font size. Value is almost always zero or negative.

  For some fonts (like CJK or barcode fonts) where there is no concept of super or subscript, this value is entirely arbitrary.

  Specified by:
    `getSubscriptPosition` in class `PDFFont`

### getSuperscriptPosition

    public float getSuperscriptPosition()

  Description copied from class: `PDFFont`

  Get the recommended position of a super-script version of this font, as a proportion of the sub-scripted font size. Value is always positive.

  For some fonts (like CJK or barcode fonts) where there is no concept of super or subscript, this value is entirely arbitrary.

  Specified by:
    `getSuperscriptPosition` in class `PDFFont`

### getSubscriptSize

    public float getSubscriptSize()

  Description copied from class: `PDFFont`

  Get the recommended size of a super/sub script version of this font, as a proportion of the normal font size. Typical value is around 0.6.

  For some fonts (like CJK or barcode fonts) where there is no concept of super or subscript, this value is entirely arbitrary.

  Specified by:
    `getSubscriptSize` in class `PDFFont`

### getStrikeoutThickness

    public float getStrikeoutThickness()

  Description copied from class: `PDFFont`
  Get the strikeout thickness, as a proportion of the font size.

### getUnderlineThickness

    public float getUnderlineThickness()

  Description copied from class: `PDFFont`
  Get the underline thickness, as a proportion of the font size.

    `getUnderlineThickness` in class `PDFFont`

### getUnderlinePosition

    public float getUnderlinePosition()

  Description copied from class: `PDFFont`
  Get the underline position, as a proportion of the font size. Like the `getDescender()` method, the returned value is almost always negative, indicating below the baseline.

  Specified by:
    `getUnderlinePosition` in class `PDFFont`

### getAscender

    public float getAscender()

  Description copied from class: `PDFFont`
  Get the Ascender for the font (the maximum height above the baseline the font extends), as a proportion of the point size.

  Specified by:
    `getAscender` in class `PDFFont`

### getDescender

    public float getDescender()

  Description copied from class: `PDFFont`
  Get the Descender for the font (the maximum height below the baseline the font extends), as a proportion of the point size. The returned value is usually negative.

  Specified by:
    `getDescender` in class `PDFFont`

### getXHeight

    public float getXHeight()

  Description copied from class: `PDFFont`
