Expand description
A Font
is used to represent a font in a
rendering-system-independent manner.
This is an Abstract Base Class, you cannot instantiate it.

impl Font
pub const NONE: Option<&'static Font> = None
sourcepub fn deserialize(
context: &Context,
bytes: &Bytes
) -> Result<Option<Font>, Error>
Available on crate feature v1_50
only.
pub fn deserialize( context: &Context, bytes: &Bytes ) -> Result<Option<Font>, Error>
v1_50
only.Loads data previously created via FontExt::serialize()
.
For a discussion of the supported format, see that function.
Note: to verify that the returned font is identical to the one that was serialized, you can compare @bytes to the result of serializing the font again.
context
a Context
bytes
the bytes containing the data
Returns
a new Font
