This abstract class is the base class, used by all effects in libopenshot.
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
This class adjusts the saturation of color on a frame's image.
void SetJsonValue(const Json::Value root)
Load Json::Value into this object.
std::string Json() const override
Get and Set JSON methods.
Saturation()
Blank constructor, useful when using Json to load the effect properties.
std::string PropertiesJSON(int64_t requested_frame) const override
Json::Value JsonValue() const override
Generate Json::Value for this object.
void SetJson(const std::string value)
Load JSON string into this object.
std::shared_ptr< Frame > GetFrame(std::shared_ptr< Frame > frame, int64_t frame_number)
This method is required for all derived classes of EffectBase, and returns a modified openshot::Frame...
Keyframe saturation
The color saturation: 0.0 = black and white, 1.0 = normal, 2.0 = double saturation.
This namespace is the default namespace for all code in the openshot library.
