Class Overview

TrueTypeFont is not called SFntFont because it is not expected to handle all types that may be housed in a such a font file. If additional types are supported later, it may make sense to create an SFnt superclass. Eg to handle sfnt-housed postscript fonts. OpenType fonts are handled by this class, and possibly should be represented by a subclass. An instance stores some information from the font file to faciliate faster access. File size, the table directory and the names of the font are the most important of these. It amounts to approx 400 bytes for a typical font. Systems with mutiple locales sometimes have up to 400 font files, and an app which loads all font files would need around 160Kbytes. So storing any more info than this would be expensive.

Public Methods

public String getFamilyName (Locale locale)

public int getFontCount ()

Returns
  • number of logical fonts. Is "1" for all but TTC files

public String getFontName (Locale locale)

public String getFullName ()

public CharToGlyphMapper getMapper ()

public String getPostscriptName ()

public void getStyleMetrics (float pointSize, float[] metrics, int offset)

The length of the metrics array must be >= offset+4, and offset must be >= 0. Typically offset is 4. This method will store the following elements in that array before returning: metrics[off+0]: strikethrough offset metrics[off+1]: strikethrough thickness metrics[off+2]: underline offset metrics[off+3]: underline thickness Note that this implementation simply returns default values; subclasses can override this method to provide more accurate values.

public boolean hasSupplementaryChars ()

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
  • a string representation of the object.
