Description

Pango Alignment Constants

The Alignment constants specify how to align the lines of a pango.Layout within the available space. If the pango.Layout is set to justify using the pango.Layout.set_justify() method, then this only has an effect for partial lines.

pango.ALIGN_LEFT

Put all available space on the right

pango.ALIGN_CENTER

Center the line within the available space

pango.ALIGN_RIGHT

Put all available space on the left

Pango Attribute Type Constants

The Attribute Type constants specify the type of a pango.Attribute.Along with the predefined values, it is possible to allocate additional values for custom attributes using the pango.attr_type_register() function. The predefined values are given below. The type of structure used to store the attribute is listed in parentheses after the description.

pango.ATTR_LANGUAGE

Specifies a pango.Language.

pango.ATTR_FAMILY

Specifies a font family name list as a string.

pango.ATTR_STYLE

Specifies a font slant style. See the pango.AttrStyle() function for more details.

pango.ATTR_WEIGHT

Specifies a font weight. See the pango.AttrWeight() function for more detail.

pango.ATTR_VARIANT

Specifies a font variant (normal or small caps). See the pango.AttrVariant() function for more detail.

pango.ATTR_STRETCH

Specifies a font stretch. See the pango.AttrStretch() function for more details.

pango.ATTR_SIZE

Specifies a font size in thousandths of a point.

pango.ATTR_FONT_DESC

Specifies a pango.FontDescription.

pango.ATTR_FOREGROUND

Specifies a foreground pango.Color.

pango.ATTR_BACKGROUND

Specifies a background pango.Color.

pango.ATTR_UNDERLINE

Specifies an underline style. See the pango.AttrUnderline() function for more details.

pango.ATTR_STRIKETHROUGH

If True the text is struck through.

pango.ATTR_RISE

Specifies the displacement of the text from the baseline.

pango.ATTR_SHAPE

Specifies a shape. See the pango.AttrShape() function for more details.

pango.ATTR_SCALE

Specifies a font size scale factor.

pango.ATTR_FALLBACK

if True, fallback to other fonts is enabled (

Pango Coverage Level Constants

pango.COVERAGE_NONE

The character is not representable with the font.

pango.COVERAGE_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.

pango.COVERAGE_APPROXIMATE

The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script.

pango.COVERAGE_EXACT

The character is represented as the correct graphical form.

Pango Direction Constants

The pango Direction constants specify a direction in the Unicode bidirectional algorithm. Not every value in this enumeration makes sense for every usage of pango Direction.

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 the Text module of the CSS3 spec for how vertical text is planned to be handled in a future version of Pango. The explanation of why pango.DIRECTION_TTB_LTR is treated as pango.DIRECTION_RTL can be found there as well.

pango.DIRECTION_LTR

A strong left-to-right direction

pango.DIRECTION_RTL

A strong right-to-left direction

pango.DIRECTION_TTB_LTR

Deprecated value; treated the same as pango.DIRECTION_RTL.

pango.DIRECTION_TTB_RTL

Deprecated value; treated the same as pango.DIRECTION_LTR

pango.DIRECTION_WEAK_LTR

A weak left-to-right direction

pango.DIRECTION_WEAK_RTL

A weak right-to-left direction

pango.DIRECTION_NEUTRAL

No direction specified

Pango Ellipsize Mode Constants

The Ellipsize Mode constants specify what sort of (if any) ellipsization should be applied to a line of 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 (...).

pango.ELLIPSIZE_NONE

No ellipsization.

pango.ELLIPSIZE_START

Omit characters at the start of the text.

pango.ELLIPSIZE_MIDDLE

Omit characters in the middle of the text.

pango.ELLIPSIZE_END

Omit characters at the end of the text.

Pango Font Mask Flag Constants

The Font Mask flag constants are bit-flags that correspond to fields in a pango.FontDescription that have been set.

pango.FONT_MASK_FAMILY

the font family is specified.

pango.FONT_MASK_STYLE

the font style is specified.

pango.FONT_MASK_VARIANT

the font variant is specified.

pango.FONT_MASK_WEIGHT

the font weight is specified.

pango.FONT_MASK_STRETCH

the font stretch is specified.

pango.FONT_MASK_SIZE

the font size is specified.

Pango Render Part Constants

pango.RENDER_PART

The pango.RENDER_PART constants define different items to render for purposes such as setting colors. Available since PyGTK 2.8.

pango.RENDER_PART_FOREGROUND

The text itself.

pango.RENDER_PART_BACKGROUND

The area behind the text.

pango.RENDER_PART_UNDERLINE

The underlined areas.

pango.RENDER_PART_STRIKETHROUGH

The strikethrough areas.

Pango Scale Constants

pango.SCALE

The pango.SCALE constant represents the scale between dimensions used for Pango distances and device units. (The definition of device units is dependent on the output device; it will typically be pixels for a screen, and points for a printer.) pango.SCALE is currently 1024, but this may be changed in the future. When setting font sizes, device units are always considered to be points (as in "12 point font"), rather than pixels.

pango.SCALE_XX_SMALL

The scale factor for three shrinking steps (1 / (1.2 * 1.2 * 1.2)).

pango.SCALE_X_SMALL

The scale factor for two shrinking steps (1 / (1.2 * 1.2)).

pango.SCALE_SMALL

The scale factor for one shrinking step (1 / 1.2).

pango.SCALE_MEDIUM

The scale factor for normal size (1.0).

pango.SCALE_LARGE

The scale factor for one magnification step (1.2).

pango.SCALE_X_LARGE

he scale factor for two magnification steps (1.2 * 1.2).

pango.SCALE_XX_LARGE

The scale factor for three magnification steps (1.2 * 1.2 * 1.2).

Pango Stretch Constants

The Stretch constants specify the width of the font relative to other designs within a family.

pango.STRETCH_ULTRA_CONDENSED

The most narrow width

pango.STRETCH_EXTRA_CONDENSED

pango.STRETCH_CONDENSED

pango.STRETCH_SEMI_CONDENSED

pango.STRETCH_NORMAL

The normal width.

pango.STRETCH_SEMI_EXPANDED

pango.STRETCH_EXPANDED

pango.STRETCH_EXTRA_EXPANDED

pango.STRETCH_ULTRA_EXPANDED

The most expanded width

Pango Style Constants

The Style constants specify the various slant styles possible for a font.

pango.STYLE_NORMAL

The font is upright.

pango.STYLE_OBLIQUE

The font is slanted in a roman style.

pango.STYLE_ITALIC

The font is slanted in an italic style.

Pango Tab Constants

The Tab constants specify where a tab stop appears relative to the text.

pango.TAB_LEFT

Pango Underline Constants

The Underline constants specify he type of underlining (if any) to be used.

pango.UNDERLINE_NONE

No underline should be drawn.

pango.UNDERLINE_SINGLE

A single underline should be drawn.

pango.UNDERLINE_DOUBLE

A double underline should be drawn.

pango.UNDERLINE_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.

pango.UNDERLINE_ERROR

a wavy underline should be drawn below. This underline is typically used to indicate an error such as a possilble mispelling; in some cases a contrasting color may automatically be used. This type of underlining is available since Pango 1.4.

Pango Variant Constants

The Variant constants specify the capitalization variant of the font.

pango.VARIANT_NORMAL

A normal font.

pango.VARIANT_SMALL_CAPS

A font with the lower case characters replaced by smaller variants of the capital characters.

pango.WEIGHT_ULTRALIGHT

The ultralight weight (= 200).

pango.WEIGHT_LIGHT

The light weight (=300).

pango.WEIGHT_NORMAL

The default weight (= 400).

pango.WEIGHT_BOLD
