## Enumerations
enum class | AttrType { INVALID , LANGUAGE , FAMILY , STYLE , WEIGHT , VARIANT , STRETCH , SIZE , FONT_DESC , FOREGROUND , BACKGROUND , UNDERLINE , STRIKETHROUGH , RISE , SHAPE , SCALE_FACTOR , FALLBACK , LETTER_SPACING , UNDERLINE_COLOR , STRIKETHROUGH_COLOR , ABSOLUTE_SIZE , GRAVITY , GRAVITY_HINT , FONT_FEATURES , FOREGROUND_ALPHA , BACKGROUND_ALPHA , ALLOW_BREAKS , SHOW , INSERT_HYPHENS , OVERLINE , OVERLINE_COLOR }
| The Pango::AttrType distinguishes between different types of attributes. More...
enum class | Underline { NONE , SINGLE , DOUBLE , LOW , ERROR , SINGLE_LINE , DOUBLE_LINE , ERROR_LINE }
| The Pango::Underline enumeration is used to specify whether text should be underlined, and if so, the type of underlining. More...
enum class | Overline { NONE , SINGLE }
| The Pango::Overline enumeration is used to specify whether text should be overlined, and if so, the type of line. More...
enum class | ShowFlags { NONE = 0x0 , SPACES = 1 << 0 , LINE_BREAKS = 1 << 1 , IGNORABLES = 1 << 2 }
| These flags affect how Pango treats characters that are normally not visible in the output. More...
enum class | Direction { LTR , RTL , TTB_LTR , TTB_RTL , WEAK_LTR , WEAK_RTL , NEUTRAL }
| The Pango::Direction type represents a direction in the Unicode bidirectional algorithm; not every value in this enumeration makes sense for every usage of Pango::Direction; for example, the return value of pango_unichar_direction() and pango_find_base_dir() cannot be Pango::Direction::WEAK_LTR or Pango::Direction::WEAK_RTL, since every character is either neutral or has a strong direction; on the other hand Pango::Direction::NEUTRAL doesn't make sense to pass to pango_itemize_with_base_dir(). More...
enum class | GravityHint { NATURAL , STRONG , LINE }
| The Pango::GravityHint defines how horizontal scripts should behave in a vertical context. More...
enum class | Style { NORMAL , OBLIQUE , ITALIC }
| An enumeration specifying the various slant styles possible for a font. More...
enum class | Variant { NORMAL , SMALL_CAPS }
| An enumeration specifying capitalization variant of the font. More...
enum class | Stretch { ULTRA_CONDENSED , EXTRA_CONDENSED , CONDENSED , SEMI_CONDENSED , NORMAL , SEMI_EXPANDED , EXPANDED , EXTRA_EXPANDED , ULTRA_EXPANDED }
| An enumeration specifying the width of the font relative to other designs within a family. More...
enum class | FontMask { FAMILY = 1 << 0 , STYLE = 1 << 1 , VARIANT = 1 << 2 , WEIGHT = 1 << 3 , STRETCH = 1 << 4 , SIZE = 1 << 5 , GRAVITY = 1 << 6 , VARIATIONS = 1 << 7 }
| The bits in a Pango::FontMask correspond to fields in a Pango::FontDescription that have been set. More...
enum class | Gravity { SOUTH , EAST , NORTH , WEST , AUTO }
| The Pango::Gravity type represents the orientation of glyphs in a segment of text. More...
enum class | ShapeFlags { NONE = 0x0 , ROUND_POSITIONS = 1 << 0 }
| Flags influencing the shaping process. More...
enum class | Script { INVALID_CODE = -1 , COMMON , INHERITED , ARABIC , ARMENIAN , BENGALI , BOPOMOFO , CHEROKEE , COPTIC , CYRILLIC , DESERET , DEVANAGARI , ETHIOPIC , GEORGIAN , GOTHIC , GREEK , GUJARATI , GURMUKHI , HAN , HANGUL , HEBREW , HIRAGANA , KANNADA , KATAKANA , KHMER , LAO , LATIN , MALAYALAM , MONGOLIAN , MYANMAR , OGHAM , OLD_ITALIC , ORIYA , RUNIC , SINHALA , SYRIAC , TAMIL , TELUGU , THAANA , THAI , TIBETAN , CANADIAN_ABORIGINAL , YI , TAGALOG , HANUNOO , BUHID , TAGBANWA , BRAILLE , CYPRIOT , LIMBU , OSMANYA , SHAVIAN , LINEAR_B , TAI_LE , UGARITIC , NEW_TAI_LUE , BUGINESE , GLAGOLITIC , TIFINAGH , SYLOTI_NAGRI , OLD_PERSIAN , KHAROSHTHI , UNKNOWN , BALINESE , CUNEIFORM , PHOENICIAN , PHAGS_PA , NKO , KAYAH_LI , LEPCHA , REJANG , SUNDANESE , SAURASHTRA , CHAM , OL_CHIKI , VAI , CARIAN , LYCIAN , LYDIAN , BATAK , BRAHMI , MANDAIC , CHAKMA , MEROITIC_CURSIVE , MEROITIC_HIEROGLYPHS , MIAO , SHARADA , SORA_SOMPENG , TAKRI , BASSA_VAH , CAUCASIAN_ALBANIAN , DUPLOYAN , ELBASAN , GRANTHA , KHOJKI , KHUDAWADI , LINEAR_A , MAHAJANI , MANICHAEAN , MENDE_KIKAKUI , MODI , MRO , NABATAEAN , OLD_NORTH_ARABIAN , OLD_PERMIC , PAHAWH_HMONG , PALMYRENE , PAU_CIN_HAU , PSALTER_PAHLAVI , SIDDHAM , TIRHUTA , WARANG_CITI , AHOM , ANATOLIAN_HIEROGLYPHS , HATRAN , MULTANI , OLD_HUNGARIAN , SIGNWRITING }
| The Pango::Script enumeration identifies different writing systems. More...
enum class | Alignment { LEFT , CENTER , RIGHT }
| A Pango::Alignment describes how to align the lines of a Pango::Layout within the available space. More...
enum class | WrapMode { WORD , CHAR , WORD_CHAR }
| A Pango::WrapMode describes how to wrap the lines of a Pango::Layout to the desired width. More...
enum class | EllipsizeMode { NONE , START , MIDDLE , END }
| The Pango::EllipsizeMode type describes what sort of (if any) ellipsization should be applied to a line of text. More...
enum class | TabAlign { LEFT }
| A Pango::TabAlign specifies where a tab stop appears relative to the text. More...

## Typedef Documentation

## ◆ Glyph

typedef PangoGlyph Pango::Glyph

A Pango::Glyph represents a single glyph in the output form of a string.

## ◆ GlyphUnit

typedef PangoGlyphUnit Pango::GlyphUnit

A Pango::GlyphUnit is used to store dimensions within Pango.

Dimensions are stored in 1/64ths of a point.

## ◆ GlyphVisAttr

typedef PangoGlyphVisAttr Pango::GlyphVisAttr

A Pango::GlyphVisAttr is used to communicate information between the shaping phase and the rendering phase.

It's contents are still evolving.

## ◆ LogAttr

typedef PangoLogAttr Pango::LogAttr

A Pango::LogAttr stores information about the attributes of a single character.

## ◆ Matrix

typedef PangoMatrix Pango::Matrix

## Function Documentation

## ◆ init()

void Pango::init | ( |  | ) |

Initialize pangomm.

You may call this more than once. You do not need to call this if you are using Gtk::Main, because it calls it for you.
