Class Overview

A font that is used to draw text on a page. It corresponds to a Font Resource in a PDF file. More than one page may reference the same Font object. A Font has a number of attributes, including an array of widths, the character encoding, and the font's resource name. PDF document can contain several different types of fonts and Font class represents a single, flat interface around all PDF font types. There are two main classes of fonts in PDF: simple and composite fonts. Simple fonts are Type1, TrueType, and Type3 fonts. All simple fonts have the following properties:

- Glyphs in the font are selected by single-byte character codes obtained from a string that is shown by the text-showing operators. Logically, these codes index into a table of 256 glyphs; the mapping from codes to glyphs is called the font's encoding. Each font program has a built-in encoding. Under some circumstances, the encoding can be altered by means described in Section 5.5.5 "Character Encoding" in PDF Reference Manual.

- Each glyph has a single set of metrics. Therefore simple fonts support only horizontal writing mode.

A composite font is one whose glyphs are obtained from a font like object called a CIDFont (e.g. CIDType0Font and CIDType0Font). A composite font is represented by a font dictionary whose Subtype value is Type0. The Type 0 font is known as the root font, while its associated CIDFont is called its descendant. CID-keyed fonts provide a convenient and efficient method for defining multiple-byte character encodings and fonts with a large number of glyphs. These capabilities provide great flexibility for representing text in writing systems for languages with large character sets, such as Chinese, Japanese, and Korean (CJK).

public double getDescent ()

The face's descender is the vertical distance from the baseline to the bottommost point of any glyph in the face. This field's value is a negative number expressed in the glyph coordinate system. For all font types except Type 3, the units of glyph space are one-thousandth of a unit of text space. Some font designs use a value different from 'bbox.yMin'.

Note: Only relevant for scalable formats.

If a String is not NULL, it containing the name of the glyph for the code point corresponding to the index. If it is NULL, then the name of the glyph is unchanged from that specified by the font's builtin encoding. For a Type 3 font, all glyph names will be present in the encoding array, and NULL entries correspond to un-encoded code points.

Note: the function can return only the following operators (Element::e_moveto, Element::e_lineto, Element::e_cubicto and optionaly Element::e_conicto if conics2cubics parameter is set to true.

Note: This function is not applicable to Type3 font and will throw an exception. Use GetType3GlyphStream instead.

Returns
  • true for non-CID based fonts such as Type1, TrueType, and Type3 All simple fonts have the following properties:

Logically, these codes index into a table of 256 glyphs; the mapping from codes to glyphs is called the font's encoding. Each font program has a built-in encoding. Under some circumstances, the encoding can be altered by means described in Section 5.5.5 "Character Encoding" in PDF Reference Manual. - Each glyph has a single set of metrics. Therefore simple fonts support only horizontal writing mode.
