Struct riddle_font::ImgFontBuilder

pub struct ImgFontBuilder { /* fields omitted */ }

A utility to construct an ImgFont given an image and a collection of glyph data.

Example

let img = Image::new(64, 64);
let mut img_font_builder = ImgFontBuilder::new();
img_font_builder.vertical_spacing(32);

img_font_builder.with_glyph(ImgFontGlyph {
    character: 'a',
    rect: Some(Rect::new([0,0], [32, 32])),
    horizontal_spacing: 32,
    .. Default::default()
});

let img_font = img_font_builder.build(img);

assert_eq!(128, img_font.render_simple("aaaa")?.width());
