Struct ImageQuality 

pub struct ImageQuality(/* private fields */);

The quality one lossy picture may be encoded at. The legal domain is 0..=max: the maximum is admitted and one more is refused, because a caller that asks for more has asked for something no encoder has, and a clamped answer tells it the picture is better than it is.

Implementations

impl ImageQuality

pub fn admit(self, asked: u32) -> Result<(), AxError>

Whether an encoder has this quality.

Errors

E_INVALID_ARGS when the asked-for quality is outside the domain; the recovery names the domain.
