Struct riddle_font::ImgFontGenerator

pub struct ImgFontGenerator { /* fields omitted */ }

A utility for generating ImgFonts from TTFonts.

Example

let ttf_font = TTFont::load(&font_bytes[..])?;

let img_font = ImgFontGenerator::new("ABCDEF", 32).generate(&ttf_font)?;

assert_eq!(6, img_font.glyphs().len());

Implementations

impl ImgFontGenerator

pub fn new(chars: &str, pixel_height: u32) -> Self

Create a new generator, specifying the set of characters to generate and the pixel height at which the font will be rendered.

pub fn packing_size_policy(
    &mut self,
    policy: ImagePackerSizePolicy
) -> &mut Self

Override the packing rule which controls how the individual glyph images are combined in to the final image. See riddle_image::packer::ImagePackerSizePolicy.

The default is riddle_image::packer::ImagePackerSizePolicy::Pow2Square.

pub fn generate(&self, ttfont: &TTFont) -> Result<ImgFont, FontError>

Build the ImgFont for the given TTFont using the parameters specified in the generator.
