f32 example about fast_image_resize

[Cykooz]

ImageView is a generic struct that doesn't own the image data. It owns only vector of slices with an image rows.
Method ImageView::new() takes Vec<&[P]>, where P is generic parameter and must be one of pixel types are provided by fast_image_resize (U8, U8x2,... U8x4,... U16x4, ... F32).

Also you can create ImageView instance from following slice types:

• &[u8] with help of method ImageView::from_buffer()

let buffer: &[u8] = ...;
let img_view: ImageView<F32> = ImageView::from_buffer(width, height, buffer).unwrap();

• &[F32] with help of method ImageView::from_pixels()

let f32_pixels: &[F32] = ...;
let img_view = ImageView::from_pixels(width, height, f32_pixels).unwrap();

Result of all of these methods will be ImageView<F32>.

If you want to get a struct that owns an image data, then you may use Image struct as a simple implementation of such type of container.

let empty_image = Image::new(width, height, PixelType::F32);
...
let image_data: Vec<u8> = ...;
let image = Image::from_vec_u8(width, height, image_data, PixelType::F32).unwrap();

Thank you very much for the detailed explanation. I will give this a try! I appreciate you taking the time to explain this to me.
