A very simple and concrete parser for *.spf
(SimplePixelFont) files for Rust. spf.rs provides
simple encoding and decoding for *.spf
binary representation through a Vec<u8>
. And also
includes optional features to conveiniently create a texture from a font rendering, which
can then be used in your favorite game engine / graphics framework.
Example
Creates a new SimplePixelFont
struct and adds the characters o
, w
, and 😊
.
use spf::core::*;
fn main() {
let mut font = SimplePixelFont::new(FV0000, Alignment::Height, 4);
font.add_character(Character::inferred(
'o',
Bitmap::inferred(&[
true, true, true, true,
true, false, false, true,
true, false, false, true,
true, true, true, true,
]),
));
font.add_character(Character::inferred(
'w',
Bitmap::inferred(&[
true, false, true, false, true,
true, false, true, false, true,
true, false, true, false, true,
true, true, true, true, true,
]),
));
font.add_character(Character::inferred(
'😊',
Bitmap::inferred(&[
false, true, true, false,
false, false, false, false,
true, false, false, true,
false, true, true, false,
]),
));
}
We can then encode the struct and use std::fs
to write to a file:
let mut file = std::fs::OpenOptions::new()
.write(true)
.create(true)
.open("./utf8ToyFont.spf")
.unwrap();
file.write_all(&font.to_vec_u8()).unwrap();
Or we can load an exsisting .spf file using std::fs
aswell:
let mut file = fs::OpenOptions::new()
.read(true)
.open("./utf8ToyFont.spf")
.unwrap();
let mut buffer: Vec<u8> = vec![];
file.read(&mut buffer).unwrap();
let font = SimplePixelFont::from_vec_u8(buffer);
