Description

The FontFace structure is used to represent a group of fonts with the same family, slant, weight, width, but varying sizes.

Synopsis

newtype FontFace = FontFace (ManagedPtr FontFace)
class GObject o => IsFontFace o
toFontFace :: (MonadIO m, IsFontFace o) => o -> m FontFace
noFontFace :: Maybe FontFace
fontFaceDescribe :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m FontDescription
fontFaceGetFaceName :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m Text
fontFaceIsSynthesized :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m Bool
fontFaceListSizes :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m (Maybe [Int32])

class GObject o => IsFontFace o Source #

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

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

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

noFontFace :: Maybe FontFace Source #

A convenience alias for Nothing :: Maybe FontFace.

Methods

describe

fontFaceDescribe Source #

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

fontFaceGetFaceName Source #

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

fontFaceIsSynthesized Source #

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.

Since: 1.18

listSizes

fontFaceListSizes Source #

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.
