使用 glium 进行简单的文本绘制

文档

lib.rs:

该crate允许您轻松地编写文本。

使用方法

// The `TextSystem` contains the shaders and elements used for text display.
let system = glium_text::TextSystem::new(&display);

// Creating a `FontTexture`, which a regular `Texture` which contains the font.
// Note that loading the systems fonts is not covered by this library.
let font = glium_text::FontTexture::new(&display, std::fs::File::open(&std::path::Path::new("my_font.ttf")).unwrap(), 24).unwrap();

// Creating a `TextDisplay` which contains the elements required to draw a specific sentence.
let text = glium_text::TextDisplay::new(&system, &font, "Hello world!");

// Finally, drawing the text is done like this:
let matrix = [[1.0, 0.0, 0.0, 0.0],
[0.0, 1.0, 0.0, 0.0],
[0.0, 0.0, 1.0, 0.0],
[0.0, 0.0, 0.0, 1.0]];
glium_text::draw(&text, &system, &mut display.draw(), matrix, (1.0, 1.0, 0.0, 1.0));
