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)

Customization

initials allows to fully customize the attributes of the image.

Default Attributes

• font: Hirgino Sans
• font_scale: 150.0
• length: 2
• width: 300
• height: 300
• contrast_ratio: 4.5
• font_color: randomly generated
• background_color: randomly generated

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.
