Spawning a SVG in Bevy

[sly quartz]

I have a String that I want to convert to a QRCode and display in Bevy. I was previously making an SVG and using bevy_egui but I'm working off bevy main in anticipation for the big changes coming with v0.11.
bevy_egui doesn't support main branch of bevy, so I was wondering what is the best current way to do this.

What could I add to this to have an example like this work with bevy main?

pub fn spawn_qr_code(mut commands: Commands, invoice_data: Res<InvoiceDataFromServer>) {
    info!("spawning QR code");
    let invoice_str = &invoice_data.invoice;
    let qr_code = QrCode::with_version(invoice_str, Version::Normal(9), EcLevel::L).unwrap();

    let image = qr_code
        .render::<svg::Color>()
        .min_dimensions(200, 200)
        .max_dimensions(300, 300)
        .dark_color(svg::Color("#800000"))
        .light_color(svg::Color("#ffff80"))
        .build();

    let a = egui_extras::RetainedImage::from_svg_bytes_with_size(
        "invoicesvg",
        image.as_bytes(),
        egui_extras::image::FitTo::Original,
    )
    .unwrap();

    // Cache QR code to be used later
    commands.insert_resource(MyQr(a))
}

Or if not SVG, i guess loading a picture from bytes dynamically.. however.. im not necessarily tied to svg format if another method is easier

You could use resvg and render it to an Image

as an image bundle?

[cerulean aurora]

yep

oh

I didn't read the last part

It's probably easier to render the image as a png instead of svg

[sly quartz]

i was unable to figure out how to use image bundle for an in memory png @cerulean aurora

i worked many hours trying to figure it out.. i was probably close.. but didn't get it 😓

seems that most of the examples were loading png's from physical files

[cerulean aurora]

try using this function

[cerulean aurora]

what were you stuck on?

[sly quartz]

i was stuck on properly getting the image to show up. I created a vec<8> for the png or something and when using that with image bundle.. nothing showed in my ui.. i can't quite remember from june26th.. is there an example of creating an arbitary png and feeding that into an image bundle?

[cerulean aurora]

I'm not sure if there's a specific example

that's very odd

i got past it by just patching egui_bevy for 11-dev of bevy
