Struct ContentRegion 

pub struct ContentRegion {
    pub pixels: Region,
    pub normalized: [f32; 4],
}

Where the image content sits in a destination: in pixels, and as [xmin, ymin, xmax, ymax] normalized by the destination size, the form unletter_norm and the semantic decoder take.

Fields

pixels: Region

The content rectangle in destination pixels.

normalized: [f32; 4]

The content rectangle normalized by the destination size.

Implementations

impl ContentRegion

pub fn new(pixels: Region, dst_w: usize, dst_h: usize) -> Self

The region of pixels in a dst_w×dst_h destination.

pub fn full(dst_w: usize, dst_h: usize) -> Self

Content that fills a dst_w×dst_h destination.

pub fn is_full(&self) -> bool

Whether the content fills the destination.

pub fn letterboxed(&self) -> Option<[f32; 4]>

The normalized content rectangle when it does not fill the destination (a letterbox), else None.

pub fn unletter(&self, b: BoundingBox) -> BoundingBox

Map a box normalized to the destination back to the content, i.e. to the source image (see unletter_norm).
