[][src]Crate initials

initials crate helps to generate customizable avatars with the initial characters from the names.

Usage

  • Extern initials crate on your project.
extern crate initials;
  • Draw the avatar by using initials::AvatarBuilder
use initials::AvatarBuilder;
 
let image = AvatarBuilder::new("Anakin Skywalker")
    .draw();

This will import dynamic RGBA image.

  • If you wish to save the image:
use initials::AvatarBuilder;

let image = AvatarBuilder::new("Anakin Skywalker")
    .draw();

image.save("avatar.jpg").unwrap();

Or, you may manipulate DynamicImage according to your needs after building.(Docs)

Manipulation
method description
with_font(str) Font file path(.ttf)
with_font_color(str) Font hex color code
with_font_scale(f32) Uniform scale of the text
with_background_color(str) Background hex color code
with_length(usize) Font length
with_height(u32) Image height
with_width(u32) Image width
with_contrast_ratio(u32) Contrast ratio for the randomly generated colors
Example
use initials::{AvatarBuilder, AvatarResult};

fn avatar() -> AvatarResult {
    AvatarBuilder::new("Anaking Skywalker")
        .with_font_color("#000000")?
        .with_background_color("#FAFAFA")?
        .with_length(1)
}

fn main() {
    let avatar = avatar().unwrap();
    let image = avatar.draw();
}
  • This will export an initials avatar A with black font and white background.

Randomization

  • By default, background color and font color will be generated by considering the contrast ratio.
use initials::{AvatarBuilder, AvatarResult};
    
fn avatar_with_random_font() -> AvatarResult {
    AvatarBuilder::new("Lucky Seven")
        .with_background_color("#FAFAFA")
}

fn avatar_with_random_background() -> AvatarResult {
    AvatarBuilder::new("Lucky Seven")
        .with_font_color("#000000")
}

fn main() {
    let img1 = avatar_with_random_background().unwrap().draw();
    let img2 = avatar_with_random_font().unwrap().draw();
}
  • Means that you may fully customize the colors or unsetted colors will be automatically generated by providing clear and readable avatars according to the contrast ratio.
