GI.Pango.Objects.FontFace

A PangoFontFace is used to represent a group of fonts with the same family, slant, weight, and width, but varying sizes.

class (GObject o, IsDescendantOf FontFace o) => IsFontFace o

Type class for types which can be safely cast to FontFace, for instance with toFontFace.

Instances

(GObject o, IsDescendantOf FontFace o) => IsFontFace o

toFontFace :: (MonadIO m, IsFontFace o) => o -> m FontFace

Cast to FontFace, for types for which this is known to be safe. For general casts, use castTo.

describe

fontFaceDescribe

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a PangoFontFace

-> m FontDescription

Returns: a newly-created PangoFontDescription structure holding the description of the face. Use fontDescriptionFree to free the result.

Returns a font description that matches the face.

The resulting font description will have the family, style, variant, weight and stretch of the face, but its size field will be unset.

getFaceName

fontFaceGetFaceName

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a PangoFontFace.

-> m Text

Returns: the face name for the face. This string is owned by the face object and must not be modified or freed.

Gets a name representing the style of this face.

Note that a font family may contain multiple faces with the same name (e.g. a variable and a non-variable face for the same style).

getFamily

fontFaceGetFamily

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a PangoFontFace

-> m FontFamily

Returns: the PangoFontFamily

Gets the PangoFontFamily that face belongs to.

isSynthesized

fontFaceIsSynthesized

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a PangoFontFace

-> m Bool

Returns: whether face is synthesized

Returns whether a PangoFontFace is synthesized.

This will be the case if the underlying font rendering engine creates this face from another face, by shearing, emboldening, lightening or modifying it in some other way.

Since: 1.18

listSizes

fontFaceListSizes

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a PangoFontFace.

-> m (Maybe [Int32])

List the available sizes for a font.

This is only applicable to bitmap fonts. For scalable fonts, stores Nothing at the location pointed to by sizes and 0 at the location pointed to by nSizes. The sizes returned are in Pango units and are sorted in ascending order.
