Tiling an image

[yutannihilation]

Scene::fill() accepts peniko::BrushRef::Image as a brush, and I expect it fills the shape with repetition of the specified image if Extend::Repeated is specified. However, the following code doesn't fill. Is this the expected result? Is something wrong in my code?

    #[rustfmt::skip]
    let colors = [
        Color::RED,  Color::BLUE, Color::BLUE,
        Color::BLUE, Color::RED,  Color::BLUE,
        Color::BLUE, Color::BLUE, Color::RED,
    ];

    let mut blob: Vec<u8> = Vec::new();
    colors.iter().for_each(|c| {
        blob.push(c.r);
        blob.push(c.g);
        blob.push(c.b);
        blob.push(c.a);
    });

    let data = vello::peniko::Blob::new(Arc::new(blob));
    let image = vello::peniko::Image::new(data, vello::peniko::Format::Rgba8, 3, 3)
        .with_extend(vello::peniko::Extend::Repeat);
    let brush = vello::peniko::BrushRef::Image(&image);

    // Draw a filled circle
    let circle = Circle::new((400.0, 400.0), 200.0);
    scene.fill(
        vello::peniko::Fill::NonZero,
        Affine::IDENTITY,
        brush,
        None,
        &circle,
    );
    scene.stroke(
        &vello::kurbo::Stroke::new(10.0),
        Affine::IDENTITY,
        Color::WHITE,
        None,
        &circle,
    );

This isn't yet implemented. See also discussion in #722 - we currently only properly support the Pad extend mode, and even then not properly. The code which would need to change would be in that same part of fine.

I don't think there's an existing issue for this, thanks for reporting.

Oh, thanks for the explanation. I didn't catch up with the discussion in #722...!
