Header file for the Keyframe class.
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 shifts the pixels of an image up, down, left, or right, and can be animated with openshot:...
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...
Keyframe y
Shift the Y coordinates (up or down)
std::string Json() const override
Generate JSON string of this object.
Json::Value JsonValue() const override
Generate Json::Value for this object.
Keyframe x
Shift the X coordinates (left or right)
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
std::string PropertiesJSON(int64_t requested_frame) const override
Shift()
Blank constructor, useful when using Json to load the effect properties.
void SetJson(const std::string value) override
Load JSON string into this object.
This namespace is the default namespace for all code in the openshot library.
