Class SVGFontElem

java.lang.Object
  com.tinyline.svg.SVGNode

public class SVGFontElem
extends SVGNode

The SVGFontElem class implements the 'font' element.

The 'font' element defines an SVG font. The SVGFontElem consists of a collection of SVGGlyphElems together with the information necessary to use those glyphs.

The SVGFontElem 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 SVGFontElem correspond 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 SVGFontElem 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 SVGFontElem 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.
