Struct TestPattern 

pub struct TestPattern { /* private fields */ }

A deterministic synthetic source: SMPTE-style colour bars with a moving marker, in Gray8, RGB565 or RGB888. It exists so a pipeline can be exercised on the host, and so a firmware can prove its wiring before a sensor is attached. Frame n is identical on every platform.

Implementations

impl TestPattern

pub fn new(geometry: Geometry, fps: u32) -> Result<Self>

A pattern source at fps frames per second (the timestamps advance by 1_000_000 / fps microseconds per frame). Only uncompressed packed formats are supported.

Trait Implementations

impl Clone for TestPattern

fn clone(&self) -> TestPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TestPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ImageSource for TestPattern

fn geometry(&self) -> Geometry

The geometry every frame from this source has right now.

fn grab<'b>(&mut self, out: &'b mut [u8]) -> Result<Frame<'b>>

Capture one frame into out. The returned view borrows out; for a JPEG source only the coded bytes are meaningful and out may be larger than the frame.
