pango Constantsthe built-in constants of the pango moduleSynopsisDescriptionPango Alignment ConstantsThe 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_LEFTPut all available space on the rightpango.ALIGN_CENTERCenter the line within the available spacepango.ALIGN_RIGHTPut all available space on the leftPango Attribute Type ConstantsThe 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_LANGUAGESpecifies a pango.Language.pango.ATTR_FAMILYSpecifies a font family name list as a string.pango.ATTR_STYLESpecifies a font slant style. See the pango.AttrStyle()
function for more details.pango.ATTR_WEIGHTSpecifies a font weight. See the pango.AttrWeight()
function for more detail.pango.ATTR_VARIANTSpecifies a font variant (normal or small caps). See the
pango.AttrVariant()
function for more detail.pango.ATTR_STRETCHSpecifies a font stretch. See the pango.AttrStretch()
function for more details.pango.ATTR_SIZESpecifies a font size in thousandths of a point.pango.ATTR_FONT_DESCSpecifies a pango.FontDescription.pango.ATTR_FOREGROUNDSpecifies a foreground pango.Color.pango.ATTR_BACKGROUNDSpecifies a background pango.Color.pango.ATTR_UNDERLINESpecifies an underline style. See the pango.AttrUnderline()
function for more details.pango.ATTR_STRIKETHROUGHIf True the text is struck
through.pango.ATTR_RISESpecifies the displacement of the text from the
baseline.pango.ATTR_SHAPESpecifies a shape. See the pango.AttrShape()
function for more details.pango.ATTR_SCALESpecifies a font size scale factor.pango.ATTR_FALLBACKif True, fallback to other fonts is
enabled (Pango Coverage Level Constantspango.COVERAGE_NONEThe character is not representable with the
font.pango.COVERAGE_FALLBACKThe 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_APPROXIMATEThe character is represented as basically the correct
graphical form, but with a stylistic variant inappropriate for
the current script.pango.COVERAGE_EXACTThe character is represented as the correct graphical
form.Pango Direction ConstantsThe 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_LTRA strong left-to-right directionpango.DIRECTION_RTLA strong right-to-left directionpango.DIRECTION_TTB_LTRDeprecated value; treated the same as
pango.DIRECTION_RTL.pango.DIRECTION_TTB_RTLDeprecated value; treated the same as
pango.DIRECTION_LTRpango.DIRECTION_WEAK_LTRA weak left-to-right directionpango.DIRECTION_WEAK_RTLA weak right-to-left directionpango.DIRECTION_NEUTRALNo direction specifiedPango Ellipsize Mode ConstantsThe 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_STARTOmit 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 ConstantsThe Font Mask flag constants are bit-flags that correspond to
fields in a pango.FontDescription
that have been set.pango.FONT_MASK_FAMILYthe font family is specified.pango.FONT_MASK_STYLEthe font style is specified.pango.FONT_MASK_VARIANTthe font variant is specified.pango.FONT_MASK_WEIGHTthe font weight is specified.pango.FONT_MASK_STRETCHthe font stretch is specified.pango.FONT_MASK_SIZEthe font size is specified.Pango Render Part Constantspango.RENDER_PARTThe pango.RENDER_PART constants
define different items to render for purposes such as setting
colors. Available since PyGTK 2.8.pango.RENDER_PART_FOREGROUNDThe text itself.pango.RENDER_PART_BACKGROUNDThe area behind the text.pango.RENDER_PART_UNDERLINEThe underlined areas.pango.RENDER_PART_STRIKETHROUGHThe strikethrough areas.Pango Scale Constantspango.SCALEThe 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_SMALLThe scale factor for three shrinking steps
(1 / (1.2 * 1.2 * 1.2)).pango.SCALE_X_SMALLThe scale factor for two shrinking steps
(1 / (1.2 * 1.2)).pango.SCALE_SMALLThe scale factor for one shrinking step
(1 / 1.2).pango.SCALE_MEDIUMThe scale factor for normal size (1.0).pango.SCALE_LARGEThe scale factor for one magnification step
(1.2).pango.SCALE_X_LARGEhe scale factor for two magnification steps
(1.2 * 1.2).pango.SCALE_XX_LARGEThe scale factor for three magnification steps
(1.2 * 1.2 * 1.2).Pango Stretch ConstantsThe Stretch constants specify the width of the font relative to
other designs within a family.pango.STRETCH_ULTRA_CONDENSEDThe most narrow widthpango.STRETCH_EXTRA_CONDENSEDpango.STRETCH_CONDENSEDpango.STRETCH_SEMI_CONDENSEDpango.STRETCH_NORMALThe normal width.pango.STRETCH_SEMI_EXPANDEDpango.STRETCH_EXPANDEDpango.STRETCH_EXTRA_EXPANDEDpango.STRETCH_ULTRA_EXPANDEDThe most expanded widthPango Style ConstantsThe Style constants specify the various slant styles possible
for a font.pango.STYLE_NORMALThe font is upright.pango.STYLE_OBLIQUEThe font is slanted in a roman style.pango.STYLE_ITALICThe font is slanted in an italic style.Pango Tab ConstantsThe Tab constants specify where a tab stop appears relative to
the text.pango.TAB_LEFTthe tab stop appears to the left of the text.Pango Underline ConstantsThe Underline constants specify he type of underlining (if any)
to be used.pango.UNDERLINE_NONENo underline should be drawn.pango.UNDERLINE_SINGLEA single underline should be drawn.pango.UNDERLINE_DOUBLEA double underline should be drawn.pango.UNDERLINE_LOWA 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_ERRORa 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 ConstantsThe Variant constants specify the capitalization variant of the
font.pango.VARIANT_NORMALA normal font.pango.VARIANT_SMALL_CAPSA font with the lower case characters replaced by
smaller variants of the capital characters.Pango Weight ConstantsThe Weight constants specify the weight (boldness) of a
font. This is a numerical value ranging from 100 to 900, but there are some
predefined values:pango.WEIGHT_ULTRALIGHTThe ultralight weight (= 200).pango.WEIGHT_LIGHTThe light weight (=300).pango.WEIGHT_NORMALThe default weight (= 400).pango.WEIGHT_BOLDThe bold weight (= 700).pango.WEIGHT_ULTRABOLDThe ultrabold weight (= 800).pango.WEIGHT_HEAVYThe heavy weight (= 900).Pango Wrap Mode ConstantsThe Wrap Mode constants specify how to wrap the lines of a pango.Layout to
the desired width.pango.WRAP_WORDwrap lines at word boundaries.pango.WRAP_CHARwrap lines at character boundaries.pango.WRAP_WORD_CHARwrap lines at word boundaries, but fall back to
character boundaries if there is not enough space for a full
word.
