fontFaceDescribe

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace

-> m FontDescription

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

Returns the family, style, variant, weight and stretch of a FontFace. The size field of the resulting font description will be unset.

getFaceName

data FontFaceGetFaceNameMethodInfo

Instances

((~) * signature (m Text), MonadIO m, IsFontFace a) => MethodInfo * FontFaceGetFaceNameMethodInfo a signature

Methods

overloadedMethod :: MethodProxy FontFaceGetFaceNameMethodInfo a -> signature -> s

fontFaceGetFaceName

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace.

-> 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 among the different faces in the FontFamily for the face. This name is unique among all faces in the family and is suitable for displaying to users.

isSynthesized

data FontFaceIsSynthesizedMethodInfo

Instances

((~) * signature (m Bool), MonadIO m, IsFontFace a) => MethodInfo * FontFaceIsSynthesizedMethodInfo a signature

Methods

overloadedMethod :: MethodProxy FontFaceIsSynthesizedMethodInfo a -> signature -> s

fontFaceIsSynthesized

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace

-> m Bool

Returns: whether face is synthesized.

Returns whether a FontFace is synthesized by the underlying font rendering engine from another face, perhaps by shearing, emboldening, or lightening it.

Instances

((~) * signature (m (Maybe [Int32])), MonadIO m, IsFontFace a) => MethodInfo * FontFaceListSizesMethodInfo a signature

Methods

overloadedMethod :: MethodProxy FontFaceListSizesMethodInfo a -> signature -> s

fontFaceListSizes

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace.

-> 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.
