Struct Geometry 

pub struct Geometry {
    pub width: u32,
    pub height: u32,
    pub format: PixelFormat,
}

Width, height and pixel format.

Fields

width: u32

Pixels per row.

height: u32

Rows.

format: PixelFormat

Pixel layout.

Implementations

impl Geometry

pub const fn new( width: u32, height: u32, format: PixelFormat, ) -> Result<Geometry, Error>

Build a geometry, rejecting a zero dimension or an odd size where the format needs even dimensions (4:2:2 needs even width, 4:2:0 even both).

pub const fn byte_len(&self) -> Option<usize>

Byte length of a tightly packed frame in this geometry, or None for a compressed format. Overflow yields None too.

pub const fn packed_stride(&self) -> Option<usize>

Bytes per row of a tightly packed (non-planar) frame.
