How to send a .svg file?

[Otter-0x4ka5h]

 let l1 = Plot::new(vec![(0., 1.), (2., 1.5), (3., 1.2), (4., 1.1)]).line_style(
    LineStyle::new()
        .colour("burlywood")
        .linejoin(LineJoin::Round),
);
let v = ContinuousView::new().add(l1);

Page::single(&v).save("line.svg").expect("saving svg");

Now I want to send this saved line.svg file.

This is working

            bot.send_photo(ChatId(####), InputFile::file("./yo.jpeg"))
            .await
            .unwrap();

but this isn't

        bot.send_photo(ChatId(####), InputFile::file("./line_and_point.svg"))
            .await
            .unwrap();

I think you can't send svg files as photos, even though it's weird that send_photo's documentation doesn't mention it (check the error you are getting though, you may have used the wrong file name for example...). You should send it as a document instead:

bot.send_document(chat_id, InputFile::file("./line.svg"))
    .await
    .unwrap();

Also note that you don't necessarily have to save it on disk to send, if you can provide the file in-memory as a Vec<u8> for example, or if you can provide an impl AsyncRead, see InputFile::memory and InputFile::read.

Yeah, I sent it through the document but the android app isn't able to open the SVG document.

I think that's just how it is, android app can't render SVG 🤷

 // plotters buffer data into image
    let mut img = image::ImageBuffer::new(820, 640);
    for (x, y, pixel) in img.enumerate_pixels_mut() {
        let offset = (y as usize * 820 + x as usize) * RGBPixel::PIXEL_SIZE;
        let r = data[offset];
        let g = data[offset + 1];
        let b = data[offset + 2];
        *pixel = image::Rgb([r, g, b]);
    }
    img.save("part.png").unwrap();

    let buf = img.to_vec();

    let bot = Bot::from_env().parse_mode(ParseMode::MarkdownV2);

    //use inputfile memory

    let photo: InputFile = InputFile::memory(buf);

    bot.send_photo(
        ChatId(106XXXX),
        photo
    ).await.unwrap();

Image is saving correctly, no mistake in Vec format
