Struct Icon

pub struct Icon { /* private fields */ }

An icon used for the window titlebar, taskbar, etc.

Implementations

impl Icon

pub fn from_rgba( rgba: Vec<u8>, width: u32, height: u32, ) -> Result<Self, BadIcon>

Creates an icon from 32bpp RGBA data.

The length of rgba must be divisible by 4, and width * height must equal rgba.len() / 4. Otherwise, this will return a BadIcon error.

fn load_icon(bytes: &[u8]) -> Icon {
    let (icon_rgba, icon_width, icon_height) = {
        let image = image::load_from_memory(bytes).unwrap().into_rgba8();
        let (width, height) = image.dimensions();
        let rgba = image.into_raw();
        (rgba, width, height)
    };
    Icon::from_rgba(icon_rgba, icon_width, icon_height).expect("Failed to open icon")
