This abstract class is the base class, used by all effects in libopenshot.
Keyframe wavelength
The length of the wave.
This namespace is the default namespace for all code in the openshot library.
Keyframe speed_y
Speed of the wave on the Y-axis.
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 shift_x
Amount to shift X-axis.
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.
Keyframe amplitude
The height of the wave.
Keyframe multiplier
Amount to multiply the wave (make it bigger)
void SetJson(const std::string value)
Load JSON string into this object.
std::string PropertiesJSON(int64_t requested_frame) const override
Wave()
Blank constructor, useful when using Json to load the effect properties.
std::string Json() const override
Get and Set JSON methods.
This class distorts an image using a wave pattern.
void SetJsonValue(const Json::Value root)
Load Json::Value into this object.
