ColorBalance

This interface is implemented by elements which can perform some color balance operation on video frames they process. For example, modifying the brightness, contrast, hue or saturation.

Example elements are 'xvimagesink' and 'colorbalance'

interface ColorBalance {

gstvideo.types.ColorBalanceType getBalanceType();

int getValue(gstvideo.color_balance_channel.ColorBalanceChannel channel);

gstvideo.color_balance_channel.ColorBalanceChannel[] listChannels();

void setValue(gstvideo.color_balance_channel.ColorBalanceChannel channel, int value);

void valueChanged(gstvideo.color_balance_channel.ColorBalanceChannel channel, int value);

ulong connectValueChanged(T callback, Flag!"After" after);

}

Functions

connectValueChanged ulong connectValueChanged(T callback, Flag!"After" after): Connect to ValueChanged signal.
getBalanceType gstvideo.types.ColorBalanceType getBalanceType(): Get the #GstColorBalanceType of this implementation.
getValue int getValue(gstvideo.color_balance_channel.ColorBalanceChannel channel): Retrieve the current value of the indicated channel, between min_value and max_value.
listChannels gstvideo.color_balance_channel.ColorBalanceChannel[] listChannels(): Retrieve a list of the available channels.
setValue void setValue(gstvideo.color_balance_channel.ColorBalanceChannel channel, int value): Sets the current value of the channel to the passed value, which must be between min_value and max_value.
valueChanged void valueChanged(gstvideo.color_balance_channel.ColorBalanceChannel channel, int value): A helper function called by implementations of the GstColorBalance interface. It fires the #GstColorBalance::value-changed signal on the instance, and the #GstColorBalanceChannel::value-changed signal on the channel object.
