Struct psf_rs::Font

source ·
pub struct Font {
    pub header: Header,
    /* private fields */
}
Expand description

The structure for the font.

Example

use psf_rs::Font;

let font = Font::load(include_bytes!("../test.psfu"));

font.display_glyph('A', |bit, x, y| {
   // Stuff
});

Fields§

§header: Header

The font header for this font.

Implementations§

source§

impl Font

source

pub fn display_glyph<T: TryInto<u32>>( &self, char: T, action: impl FnMut(u8, u8, u8) )

Displays a glyph. This will NOT trim the glyph, so you will still get the vertical padding.

Arguments
  • char - Pretty self explanitory. A character or integer, that must represent a glyph on the ASCII table.
  • action - A closure that takes in 3 values, the bit (always 0 or 1), the x, and the y.
Panics
  • If the character can’t be properly converted into a u32.
  • If the character can’t be described with 2 bytes or less in UTF-8.
source

pub fn load(raw: &[u8]) -> Self

Loads a font.

Arguments
  • raw - The raw bytes for the font file itself.
Panics
  • If the file header is incomplete/corrupted in pretty much any way.
  • If the magic doesn’t match.
  • If the file size doesn’t is bigger than 0x4000 (16384) bytes.
