Expand description

Trait containing all ColorBalance methods.

§Implementors

ColorBalance

Provided Methods§

source

fn balance_type(&self) -> ColorBalanceType

Get the ColorBalanceType of this implementation.

§Returns

A the ColorBalanceType.

source

fn value(&self, channel: &impl IsA<ColorBalanceChannel>) -> i32

Retrieve the current value of the indicated channel, between min_value and max_value.

See Also: The GstColorBalanceChannel.min_value and GstColorBalanceChannel.max_value members of the ColorBalanceChannel object.

§channel

A ColorBalanceChannel instance

§Returns

The current value of the channel.

source

fn list_channels(&self) -> Vec<ColorBalanceChannel>

Retrieve a list of the available channels.

§Returns

A GList containing pointers to ColorBalanceChannel objects. The list is owned by the ColorBalance instance and must not be freed.

source

fn set_value(&self, channel: &impl IsA<ColorBalanceChannel>, value: i32)

Sets the current value of the channel to the passed value, which must be between min_value and max_value.

See Also: The GstColorBalanceChannel.min_value and GstColorBalanceChannel.max_value members of the ColorBalanceChannel object.

§channel

A ColorBalanceChannel instance

§value

The new value for the channel.

source

fn value_changed(&self, channel: &impl IsA<ColorBalanceChannel>, value: i32)

A helper function called by implementations of the GstColorBalance interface. It fires the value-changed signal on the instance, and the value-changed signal on the channel object.

§channel

A ColorBalanceChannel whose value has changed

§value

The new value of the channel

source

fn connect_value_changed<F: Fn(&Self, &ColorBalanceChannel, i32) + Send + Sync + 'static>( &self, f: F ) -> SignalHandlerId

Fired when the value of the indicated channel has changed.

§channel

The ColorBalanceChannel

§value

The new value

Object Safety§

This trait is not object safe.
