GI.Pango.Objects.FontFace
Description
A PangoFontFace is used to represent a group of fonts with
the same family, slant, weight, and width, but varying sizes.
Synopsis
- newtype FontFace = FontFace (ManagedPtr FontFace)
- class (GObject o, IsDescendantOf FontFace o) => IsFontFace o
- toFontFace :: (MonadIO m, IsFontFace o) => o -> m FontFace
- fontFaceDescribe :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m FontDescription
- fontFaceGetFaceName :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m Text
- fontFaceGetFamily :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m FontFamily
- fontFaceIsSynthesized :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m Bool
- fontFaceListSizes :: (HasCallStack, MonadIO m, IsFontFace a) => a -> m (Maybe [Int32])
Exported types

Setters
describe
Arguments
| :: (HasCallStack, MonadIO m, IsFontFace a) | |
| => a |
|
| -> m FontDescription | Returns: a newly-created |
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
Arguments
| :: (HasCallStack, MonadIO m, IsFontFace a) | |
| => a |
|
| -> 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.
The name identifies the face among the different faces
in the PangoFontFamily for the face. It is suitable
for displaying to users.
getFamily
Arguments
| :: (HasCallStack, MonadIO m, IsFontFace a) | |
| => a |
|
| -> m FontFamily | Returns: the |
Gets the PangoFontFamily that face belongs to.

isSynthesized
fontFaceIsSynthesized Source #
Arguments
| :: (HasCallStack, MonadIO m, IsFontFace a) | |
| => a |
|
| -> m Bool | Returns: whether |
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
Arguments
| :: (HasCallStack, MonadIO m, IsFontFace a) | |
| => a |
|
| -> 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.
