[−][src]Struct ab_glyph::FontVec
Font data handle stored in a Vec<u8>
+ parsed data.
See Font
for more methods.
Also see FontRef
.
Example
use ab_glyph::{Font, FontVec}; let font = FontVec::try_from_vec_and_index(owned_font_data, 0)?; assert_eq!(font.glyph_id('s'), ab_glyph::GlyphId(56));
Implementations
impl FontVec
[src]
pub fn try_from_vec(data: Vec<u8>) -> Result<Self, InvalidFont>
[src]
Creates an FontVec
from owned data.
For font collections see
FontVec::try_from_vec_and_index
.
Example
let font = FontVec::try_from_vec(owned_font_data)?;
pub fn try_from_vec_and_index(
data: Vec<u8>,
index: u32
) -> Result<Self, InvalidFont>
[src]
data: Vec<u8>,
index: u32
) -> Result<Self, InvalidFont>
Creates an FontVec
from owned data.
You can set index for font collections. For simple fonts use 0
or
FontVec::try_from_vec
.
Example
let font = FontVec::try_from_vec_and_index(owned_font_data, 0)?;
