//! `initials` crate helps to generate customizable avatars with the initial characters from the names.
//!
//! # Usage
//!
//! - Draw the avatar by using `initials_revamped::AvatarBuilder`
//! ```
//! use initials_revamped::AvatarBuilder;
//!
//! let image = AvatarBuilder::new("Anakin Skywalker")
//! .draw();
//!
//! ```
//! This will import dynamic RGBA image.
//!
//! - If you wish to save the image:
//! ```
//! use initials_revamped::AvatarBuilder;
//!
//! let image = AvatarBuilder::new("Anakin Skywalker")
//! .draw();
//!
//! image.save("avatar.jpg").unwrap();
//! ```
//!
//! Or, you may use the resulting buffer to store the image data in a variable
//! ```
//! use image::ImageOutputFormat;
//! use initials_revamped::AvatarBuilder;
//! use std::io::Cursor;
//!
//! let image = AvatarBuilder::new("Anakin Skywalker")
//! .draw();
//!
//! let mut raw_bytes: Vec<u8> = Vec::new();
//! image.write_to(&mut Cursor::new(&mut raw_bytes), ImageOutputFormat::Png)?;
//! ```
//!
//! # Customization
//!
//! `initials_revamped` allows to fully customize the attributes of the image.
//!
//! ##### Default Attributes
//! - **font:** Roboto Regular
//! - **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_data(Vec<u8>) | Font binary data |
//! | 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 |
//! | with_blur(f32) | Applied Gaussian Filter |
//!
//! ##### Example
//!
//! ```
//!
//! use initials_revamped::{AvatarBuilder, AvatarResult};
//!
//! fn avatar() -> AvatarResult {
//! let custom_font = include_bytes!("fonts/ComicSans.ttf").to_vec();
//!
//! AvatarBuilder::new("Anaking Skywalker")
//! .with_font_color("#000000")?
//! .with_font_data(custom_font)?
//! .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, white background and Comic Sans as its font.
//!
//!
//! # Randomization
//!
//! - By default, `background color` and `font color` will be generated by considering the contrast ratio.
//!
//! ```
//! use initials_revamped::{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.
