Font configuration

Generally, you can use the following fonts out of box:

• CaskaydiaCove Nerd Font, which is perfect font for rendering code.
• Pacifico, which is popular font for rendering watermark.

Custom font

And by default, CodeSnap also loads system fonts, so you can use any font installed on your system.

Otherwise, if you don't want to install any external fonts on your system, you can put the font somewhere, and let CodeSnap load it for you, just like custom theme does.

Let's say we put the font in path/to/font.ttf, which name is Foo Font, and we want to use it for rendering code:

let snapshot = CodeSnap::from_default_theme()?
    .fonts_folders(vec!["path/to".to_string()]) 
    .content(code_content)
    .build()?
    .create_snapshot()?;

Then use the font for rendering code:

let code_config = CodeConfigBuilder::default() 
    .font_family("Foo Font") 
    .build()?; 
 
let snapshot = CodeSnap::from_default_theme()?
    .fonts_folders(vec!["path/to".to_string()])
    .code_config(code_config) 
    .content(code_content)
    .build()?
    .create_snapshot()?;

Custom watermark font

You can also use custom font for watermark, just like custom font for code.

Similar to the custom code font, if CodeSnap loads the font once, it will be used for both code and watermark.

let watermark = WatermarkBuilder::default() 
    .font_family("Foo Font") 
    .build()?; 
 
let snapshot = CodeSnap::from_default_theme()?
    .code_config(code_config)
    .watermark(watermark) 
    .fonts_folders(vec!["path/to".to_string()])
    .content(code_content)
    .build()?
    .create_snapshot()?;
