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 affects partial lines.

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

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.

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 GLib::UnicodeScript enumeration instead, whose values are interchangeable with Pango::Script.

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)

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.

Enumerator
LEFT
RIGHT
CENTER
DECIMAL	Text before the first occurrence of the decimal point character appears to the left of the tab stop position (until the available space is filled), the rest to the right. Since pangomm 1.50:

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
