## Enumeration Type Documentation

## ◆ Alignment

enum class Pango::Alignment
| strong

`Pango::Alignment` describes how to align the lines of a `Pango::Layout` within the available space.

If the `Pango::Layout` is set to justify using Pango::Layout::set_justify(), this only has effect for partial lines.

See Pango::Layout::set_auto_dir() for how text direction affects the interpretation of `PangoAlignment values.

Enumerator
LEFT | Put all available space on the right. The text appears to the right of the tab stop position.
CENTER | Center the line within the available space. The text is centered at the tab stop position until the available space is filled.
RIGHT | Put all available space on the left. The text appears to the left of the tab stop position until the available space is filled.

## ◆ AttrType

enum class Pango::AttrType
| strong

## ◆ BaselineShift

enum Pango::BaselineShift_Wrapper::BaselineShift

An enumeration that affects baseline shifts between runs.

Since pangomm 2.50:

Enumerator
NONE | Leave the baseline unchanged.
SUPERSCRIPT | Shift the baseline to the superscript position, relative to the previous run.
SUBSCRIPT | Shift the baseline to the subscript position, relative to the previous run.

## ◆ Direction

enum class Pango::Direction
| strong

`Pango::Direction` 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 unichar_direction() and 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 itemize_with_base_dir().

The Pango::Direction::TTB_LTR, Pango::Direction::TTB_RTL values come from an earlier interpretation of this enumeration as the writing direction of a block of text and are no longer used; See `Pango::Gravity` for how vertical text is handled in Pango.

If you are interested in text direction, you should really use fribidi directly. `Pango::Direction` is only retained because it is used in some public apis.

Enumerator
LTR | A strong left-to-right direction.
RTL | A strong right-to-left direction.
TTB_LTR | Deprecated value; treated the same as Pango::Direction::RTL.
TTB_RTL | Deprecated value; treated the same as Pango::Direction::LTR.
WEAK_LTR | A weak left-to-right direction.
WEAK_RTL | A weak right-to-left direction.
NEUTRAL | No direction specified.

## ◆ EllipsizeMode

enum class Pango::EllipsizeMode
| strong

`Pango::EllipsizeMode` describes what sort of ellipsization should be applied to text.

In the ellipsization process characters are removed from the text in order to make it fit to a given width and replaced with an ellipsis.

Enumerator
NONE |
START | Omit characters at the start of the text.
MIDDLE | Omit characters in the middle of the text.
END | Omit characters at the end of the text.

## ◆ FontMask

enum class Pango::FontMask
| strong

The bits in a `Pango::FontMask` correspond to the set fields in a `Pango::FontDescription`.

Bitwise operators:
  `FontMask operator|(FontMask, FontMask)`
  `FontMask operator&(FontMask, FontMask)`
  `FontMask operator^(FontMask, FontMask)`
  `FontMask operator~(FontMask)`
  `FontMask& operator|=(FontMask&, FontMask)`
  `FontMask& operator&=(FontMask&, FontMask)`
  `FontMask& operator^=(FontMask&, FontMask)`

Enumerator
FAMILY |
STYLE |
VARIANT |
WEIGHT |
STRETCH |
SIZE |
GRAVITY |
VARIATIONS | OpenType font variations are specified (Since: 1.42).

## ◆ FontScale

enum class Pango::FontScale
| strong

An enumeration that affects font sizes for superscript and subscript positioning and for (emulated) Small Caps.

Since pangomm 2.50:

Enumerator
NONE |
SUPERSCRIPT | Change the font to a size suitable for superscripts.
SUBSCRIPT | Change the font to a size suitable for subscripts.
SMALL_CAPS | Change the font to a size suitable for Small Caps. A font with the lower case characters replaced by smaller variants of the capital characters. Since pangomm 1.50:

## ◆ Gravity

enum class Pango::Gravity
| strong

`Pango::Gravity` represents the orientation of glyphs in a segment of text.

This is useful when rendering vertical text layouts. In those situations, the layout is rotated using a non-identity Pango::Matrix, and then glyph orientation is controlled using `Pango::Gravity`.

Not every value in this enumeration makes sense for every usage of `Pango::Gravity`; for example, Pango::Gravity::AUTO only can be passed to Pango::Context::set_base_gravity() and can only be returned by Pango::Context::get_base_gravity().

See also: Pango::GravityHint

Since pangomm 1.16:

Enumerator
SOUTH | Glyphs stand upright (default) .
EAST | Glyphs are rotated 90 degrees counter-clockwise. .
NORTH | Glyphs are upside-down. .
WEST | Glyphs are rotated 90 degrees clockwise. .
AUTO | Gravity is resolved from the context matrix.

## ◆ GravityHint

enum class Pango::GravityHint
| strong

`Pango::GravityHint` defines how horizontal scripts should behave in a vertical context.

That is, English excerpts in a vertical paragraph for example.

See also Pango::Gravity

Since pangomm 1.16:

Enumerator
NATURAL | Scripts will take their natural gravity based on the base gravity and the script. This is the default.
STRONG | Always use the base gravity set, regardless of the script.
LINE | For scripts not in their natural direction (eg. Latin in East gravity), choose per-script gravity such that every script respects the line progression. This means, Latin and Arabic will take opposite gravities and both flow top-to-bottom for example.

## ◆ Level

enum class Pango::Coverage::Level
| strong

`Pango::CoverageLevel` is used to indicate how well a font can represent a particular Unicode character for a particular script.

Since 1.44, only Pango::Coverage::Level::NONE and Pango::Coverage::Level::EXACT will be returned.

Enumerator
NONE | The character is not representable with the font.
FALLBACK | The character is represented in a way that may be comprehensible but is not the correct graphical form. For instance, a Hangul character represented as a a sequence of Jamos, or a Latin transliteration of a Cyrillic word.
APPROXIMATE | The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script.
EXACT | The character is represented as the correct graphical form.

## ◆ Overline

enum class Pango::Overline
| strong

The `Pango::Overline` enumeration is used to specify whether text should be overlined, and if so, the type of line.

Since pangomm 1.46:

Enumerator
NONE |
SINGLE |

## ◆ Part

enum class Pango::Renderer::Part
| strong

`Pango::RenderPart` defines different items to render for such purposes as setting colors.

Since pangomm 1.8:

Enumerator
FOREGROUND | The text itself.
BACKGROUND | The area behind the text.
UNDERLINE | Underlines.
STRIKETHROUGH | Strikethrough lines.
OVERLINE | Overlines.

## ◆ Script

enum class Pango::Script
| strong

The `Pango::Script` enumeration identifies different writing systems.

The values correspond to the names as defined in the Unicode standard. See Unicode Standard Annex 24: Script names

Note that this enumeration is deprecated and will not be updated to include values in newer versions of the Unicode standard. Applications should use the `UnicodeScript` enumeration instead, whose values are interchangeable with `Pango::Script`.

Enumerator
INVALID_CODE | A value never returned from pango_script_for_unichar().
COMMON | A character used by multiple different scripts.
INHERITED | A mark glyph that takes its script from the base glyph to which it is attached.
ARABIC | Arabic.
ARMENIAN | Armenian.

## ◆ ShapeFlags

enum class Pango::ShapeFlags
| strong

Flags influencing the shaping process.

`Pango::ShapeFlags` can be passed to pango_shape_with_flags().

Since pangomm 2.44:

Bitwise operators:
  `ShapeFlags operator|(ShapeFlags, ShapeFlags)`
  `ShapeFlags operator&(ShapeFlags, ShapeFlags)`
  `ShapeFlags operator^(ShapeFlags, ShapeFlags)`
  `ShapeFlags operator~(ShapeFlags)`
  `ShapeFlags& operator|=(ShapeFlags&, ShapeFlags)`
  `ShapeFlags& operator&=(ShapeFlags&, ShapeFlags)`
  `ShapeFlags& operator^=(ShapeFlags&, ShapeFlags)`

Enumerator
NONE |
ROUND_POSITIONS | Round glyph positions and widths to whole device units. This option should be set if the target renderer can't do subpixel positioning of glyphs.

## ◆ ShowFlags

enum class Pango::ShowFlags
| strong

These flags affect how Pango treats characters that are normally not visible in the output.

Since pangomm 1.44:

Bitwise operators:
  `ShowFlags operator|(ShowFlags, ShowFlags)`
  `ShowFlags operator&(ShowFlags, ShowFlags)`
  `ShowFlags operator^(ShowFlags, ShowFlags)`
  `ShowFlags operator~(ShowFlags)`
  `ShowFlags& operator|=(ShowFlags&, ShowFlags)`
  `ShowFlags& operator&=(ShowFlags&, ShowFlags)`
  `ShowFlags& operator^=(ShowFlags&, ShowFlags)`

Enumerator
NONE |
SPACES | Render spaces, tabs and newlines visibly.
LINE_BREAKS | Render line breaks visibly.
IGNORABLES | Render default-ignorable Unicode characters visibly.

## ◆ Stretch

enum class Pango::Stretch
| strong

An enumeration specifying the width of the font relative to other designs within a family.

Enumerator
ULTRA_CONDENSED | Ultra condensed width.
EXTRA_CONDENSED | Extra condensed width.
CONDENSED | Condensed width.
SEMI_CONDENSED | Semi condensed width.
NORMAL |
SEMI_EXPANDED | Semi expanded width.
EXPANDED | Expanded width.
EXTRA_EXPANDED | Extra expanded width.
ULTRA_EXPANDED | Ultra expanded width.

## ◆ Style

enum class Pango::Style
| strong

An enumeration specifying the various slant styles possible for a font.

Enumerator
NORMAL | The font is upright. The normal width. A normal font.
OBLIQUE | The font is slanted, but in a roman style.
ITALIC | The font is slanted in an italic style.

## ◆ TabAlign

enum class Pango::TabAlign
| strong

`Pango::TabAlign` specifies where the text appears relative to the tab stop position.

Support for tab alignments other than Pango::TabAlign::LEFT was added in Pango 1.50.

Enumerator
LEFT |
RIGHT |
CENTER |
DECIMAL | Text before the first '. ' appears to the left of the tab stop position (until the available space is filled), the rest to the right.

## ◆ TextTransform

enum class Pango::TextTransform
| strong

An enumeration that affects how Pango treats characters during shaping.

Since pangomm 2.50:

Enumerator
NONE |
LOWERCASE | Display letters and numbers as lowercase.
UPPERCASE | Display letters and numbers as uppercase.
CAPITALIZE | Display the first character of a word in titlecase.

## ◆ Underline

enum class Pango::Underline
| strong

The `Pango::Underline` enumeration is used to specify whether text should be underlined, and if so, the type of underlining.

Enumerator
NONE | No underline should be drawn. No ellipsization. Default value. Leave the font size unchanged. Leave text unchanged. No special treatment for invisible characters. No overline should be drawn.
SINGLE | A single underline should be drawn. Draw a single line above the ink extents of the text being underlined.
DOUBLE | A double underline should be drawn.
LOW | A single underline should be drawn at a position beneath the ink extents of the text being underlined. This should be used only for underlining single characters, such as for keyboard accelerators. Pango::Underline::SINGLE should be used for extended portions of text.
ERROR | An underline indicating an error should be drawn below. The exact style of rendering is up to the `Pango::Renderer` in use, but typical styles include wavy or dotted lines. This underline is typically used to indicate an error such as a possible mispelling; in some cases a contrasting color may automatically be used. This type of underlining is available since Pango 1.4.
SINGLE_LINE | Like PANGO_UNDERLINE_SINGLE, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.
DOUBLE_LINE | Like PANGO_UNDERLINE_DOUBLE, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.
ERROR_LINE | Like PANGO_UNDERLINE_ERROR, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.

## ◆ Variant

enum class Pango::Variant
| strong

An enumeration specifying capitalization variant of the font.

Enumerator
NORMAL |
SMALL_CAPS |
ALL_SMALL_CAPS | A font with all characters replaced by smaller variants of the capital characters. Since pangomm 1.50:
PETITE_CAPS | A font with the lower case characters replaced by smaller variants of the capital characters. Petite Caps can be even smaller than Small Caps. Since pangomm 1.50:
ALL_PETITE_CAPS | A font with all characters replaced by smaller variants of the capital characters. Petite Caps can be even smaller than Small Caps. Since pangomm 1.50:
UNICASE | A font with the upper case characters replaced by smaller variants of the capital letters. Since pangomm 1.50:
TITLE_CAPS | A font with capital letters that are more suitable for all-uppercase titles. Since pangomm 1.50:

## ◆ Weight

enum Pango::Weight_Wrapper::Weight

An enumeration specifying the weight (boldness) of a font.

This is a numerical value ranging from 100 to 1000, but there are some predefined values.

Enumerator
THIN | The thin weight (= 100; Since: 1.24).
ULTRALIGHT | The ultralight weight (= 200).
LIGHT | The light weight (= 300).
SEMILIGHT | The semilight weight (= 350; Since: 1.36.7).

## ◆ WrapMode

enum class Pango::WrapMode
| strong

`Pango::WrapMode` describes how to wrap the lines of a `Pango::Layout` to the desired width.

For PANGO_WRAP_WORD, Pango uses break opportunities that are determined by the Unicode line breaking algorithm. For PANGO_WRAP_CHAR, Pango allows breaking at grapheme boundaries that are determined by the Unicode text segmentation algorithm.

Enumerator
WORD |
CHAR | Wrap lines at character boundaries.
WORD_CHAR | Wrap lines at word boundaries, but fall back to character boundaries if there is not enough space for a full word.
