Struct BrightnessContrastEffect

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

Implementations

impl BrightnessContrastEffect

pub fn new() -> BrightnessContrastEffect

Creates a new BrightnessContrastEffect to be used with ActorExt::add_effect

Returns

the newly created BrightnessContrastEffect or None. Use gobject::ObjectExt::unref when done.

pub fn get_brightness(&self) -> (f32, f32, f32)

Retrieves the change in brightness used by self.

red

return location for red component of the change in brightness

green

return location for green component of the change in brightness

blue

return location for blue component of the change in brightness

pub fn get_contrast(&self) -> (f32, f32, f32)

Retrieves the contrast value used by self.

red

return location for red component of the change in contrast

green

return location for green component of the change in contrast

blue

return location for blue component of the change in contrast

pub fn set_brightness(&self, brightness: f32)

The range of brightness is [-1.0, 1.0], where 0.0 designates no change; a value below 0.0 indicates a decrease in brightness; and a value above 0.0 indicates an increase of brightness.

brightness

the brightness change for all three components (r, g, b)

pub fn set_brightness_full(&self, red: f32, green: f32, blue: f32)

The range for each component is [-1.0, 1.0] where 0.0 designates no change, values below 0.0 mean a decrease in brightness, and values above indicate an increase.

red

red component of the change in brightness

green

green component of the change in brightness

blue

blue component of the change in brightness

pub fn set_contrast(&self, contrast: f32)

The range for contrast is [-1.0, 1.0], where 0.0 designates no change; a value below 0.0 indicates a decrease in contrast; and a value above 0.0 indicates an increase.

contrast

contrast change for all three channels

pub fn set_contrast_full(&self, red: f32, green: f32, blue: f32)

The range for each component is [-1.0, 1.0] where 0.0 designates no change, values below 0.0 mean a decrease in contrast, and values above indicate an increase.

red

red component of the change in contrast

green

green component of the change in contrast

blue

blue component of the change in contrast

pub fn connect_property_brightness_notify<F: Fn(&BrightnessContrastEffect) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_property_contrast_notify<F: Fn(&BrightnessContrastEffect) + 'static>( &self, f: F, ) -> SignalHandlerId

Trait Implementations

impl Clone for BrightnessContrastEffect

fn clone(&self) -> BrightnessContrastEffect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BrightnessContrastEffect

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

Formats the value using the given formatter.

impl Default for BrightnessContrastEffect

fn default() -> Self

Returns the “default value” for a type.

impl Display for BrightnessContrastEffect

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

Formats the value using the given formatter.

impl Hash for BrightnessContrastEffect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for BrightnessContrastEffect

fn cmp(&self, other: &BrightnessContrastEffect) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: ObjectType> PartialEq<T> for BrightnessContrastEffect

fn eq(&self, other: &T) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ObjectType> PartialOrd<T> for BrightnessContrastEffect

fn partial_cmp(&self, other: &T) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
