pub struct Palettes<'a> {
    cpal: Option<&'a Cpal<'a>>,
}

Provides access to the color palettes in a font.

Fields

cpal: Option<&'a Cpal<'a>>

Implementations

impl<'a> Palettes<'a>

pub fn len(&self) -> u32

Returns the number of palettes, or zero if the font has no CPAL table.

pub fn is_empty(&self) -> bool

Returns true if there are no palettes.

pub fn get(&self, index: u32) -> Option<Palette<'a>>

Returns the palette at index. Index zero is the default palette.

pub fn iter(&self) -> impl Iterator<Item = Palette<'a>> + 'a

Returns an iterator over the palettes, in index order.

pub fn color_label(&self, color_index: u32) -> Option<NameId>

Returns the name ID for the label of the color at color_index, if the table has one.

The label applies to that color in every palette.

Trait Implementations

impl<'a> Clone for Palettes<'a>

fn clone(&self) -> Palettes<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
