Struct riddle_font::TTFont

pub struct TTFont { /* fields omitted */ }

Represents a parsed TTF file, and facilitates simple rendering

Implementations

impl TTFont

pub fn new<R: Read>(r: R) -> Result<Self, FontError>

Construct a new TTFont from a Read instance. The source will be read to the end, and the entire buffer parsed as a TTF font file.

let ttf_bytes = include_bytes!("../../example_assets/Roboto-Regular.ttf");
let font = TTFont::new(&ttf_bytes[..])?;

pub fn render_simple(
    &self,
    text: &str,
    pixel_height: u32
) -> Result<Image, FontError>

Render a string in this font to an image. It will only be a single line of text, even if newlines are present.

Arguments

• text - The string to be rendered, as a single line of text.
• pixel_height - The font size (in pixels) to render the font in. The output image will have the same height.

Example

let font = TTFont::new(&ttf_bytes[..])?;
let image = font.render_simple("A String", 24)?;
