# FontProvider

The font provider is responsible to provide fonts to the library.

Before a font can be used it must be registered.

## Manual font registration

Fonts can be registered manually.

Provide the name alias ("droid" below) and the font file.

```rust
let mut font_provider = FontProvider::new();
font_provider
    .register("droid", "assets/fonts/DroidSans.ttf")
    .unwrap();
```

## Automatic font registration

Given there is a file describing the font registrations, the font provider can be created this way:

```rust
   let font_provider = FontProvider::from_file("assets/fonts.json");
 ```

## Format of the font registrations file

It's a JSON file containing an array of font registrations.

```json
[
    {
        "name": "droid",
        "file": "fonts/DroidSans.ttf"
    }
]
```
