Enum ResizeMode

Source
pub enum ResizeMode {
    None,
    CropAndScale,
}
Expand description

The means by which the resolution can be derived by the client.

§Note

The enumeration is not exhaustive and merely provides a list of known values.

Variants§

§

None

This resolution and frame rate is offered by the camera, its driver, or the OS.

§Note

The user agent MAY report this value to disguise concurrent use, but only when the camera is in use in another browsing context.

§Important

This value is a possible finger-printing surface.

§

CropAndScale

This resolution is downscaled and/or cropped from a higher camera resolution by the user agent, or its frame rate is decimated by the User Agent.

§Important

The media MUST NOT be upscaled, stretched or have fake data created that did not occur in the input source.
