Example usage

• Apply horizontal Sobel filter:

  use image_conv::conv;
  use image_conv::{Filter, PaddingType};
  use photon_rs::native::{open_image, save_image};

  fn main() {
      // Open an image
      let img = open_image("img.jpg").expect("No such file found");

      // Create a filter
      let sobel_x: Vec<f32> = vec![1.0, 0.0, -1.0, 2.0, 0.0, -2.0, 1.0, 0.0, -1.0];
      let filter = Filter::from(sobel_x, 3, 3);

      // Apply convolution    
      let img_conv = conv::convolution(&img, filter, 1, PaddingType::UNIFORM(1));
      save_image(img_conv, "img_conv.jpg");
  }
