This abstract class is the base class, used by all effects in libopenshot.
This class shifts the hue of an image, and can be animated with openshot::Keyframe curves over time.
Keyframe hue
Shift the hue coordinates (left or right)
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
Hue()
Default constructor, useful when using Json to load the effect properties.
void SetJson(const std::string value) override
Load JSON string into this object.
std::shared_ptr< openshot::Frame > GetFrame(int64_t frame_number) override
This method is required for all derived classes of ClipBase, and returns a new openshot::Frame object...
std::string PropertiesJSON(int64_t requested_frame) const override
std::string Json() const override
Generate JSON string of this object.
Json::Value JsonValue() const override
Generate Json::Value for this object.
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
This namespace is the default namespace for all code in the openshot library.
