Class TinyFont

java.lang.Object

public final class TinyFont

extends java.lang.Object

The TinyFont class defines a collection of glyphs together with the information necessary to use those glyphs.

The TinyFont includes the information necessary to map characters to glyphs, to determine the size of glyph areas and to position the glyph area.

The characteristics and attributes of TinyFont correspond closely to the SVG fonts. Various font metrics, such as advance values and baseline locations, and the glyph outlines themselves, are expressed in units that are relative to an abstract square whose height is the intended distance between lines of type in the same type size.

This square is called the EM square and it is the design grid on which the glyph outlines are defined. The value of the units-per-em attribute on the TinyFont specifies how many units the EM square is divided into. Common values are, for example, 1000 (Type 1) and 2048 (TrueType, TrueType GX and Open-Type).

The design grid for TinyFont fonts, along with the initial coordinate system for the glyphs, has the y-axis pointing upward for consistency with accepted industry practice for many popular font formats.
