what is Rust's best way to display and dynamically generated image?
I have
let image : ImageBuffer<Rgb<u8>, Vec<u8>> = ...
How do I show it in a GUI?
I tried with fltk, but didn't find anything usable for ImageBuffer.
use fltk::...
let app = App::default().with_scheme(AppScheme::Gleam);
let mut wind = Window::new(100, 100, 400, 300, "Hello from rust");
wind.set_image(Some(image));
won't work because:
the trait `ImageExt` is not implemented for image::buffer_::ImageBuffer<image::color::Rgb<u8>, Vec<u8>>`
Do I have to encode my ImageBuffer image to some specific format, so that the GUI library can decode it back and display it afterward?
Or maybe I should use some other UI library then fltk?
I was able to solve it with the help from mo_al_'s answear. I just had to use into_raw(), because to_rgb8() or into_rgb8() were not implemented for type.
let w = image.width() as i32;
let h = image.height() as i32;
let image_rgb = RgbImage::new(&domain_image.into_raw(), w, h, ColorDepth::Rgb8).unwrap();
...
let mut frame = Frame::new(0, 0, w, h, "");
frame.set_image(Some(image_rgb));
