Header file for EffectBase class.
Header file for Frame class.
Header file for JSON class.
Header file for the Keyframe class.
This class adjusts the blur of an image, and can be animated with openshot::Keyframe curves over time...
Keyframe vertical_radius
Vertical blur radius keyframe. The size of the vertical blur operation in pixels.
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 Json() const override
Generate JSON string of this object.
Json::Value JsonValue() const override
Generate Json::Value for this object.
Blur()
Blank constructor, useful when using Json to load the effect properties.
Keyframe iterations
Iterations keyframe. The # of blur iterations per pixel. 3 iterations = Gaussian.
std::string PropertiesJSON(int64_t requested_frame) const override
void SetJson(const std::string value) override
Load JSON string into this object.
Keyframe sigma
Sigma keyframe. The amount of spread in the blur operation. Should be larger than radius.
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
Keyframe horizontal_radius
Horizontal blur radius keyframe. The size of the horizontal blur operation in pixels.
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 namespace is the default namespace for all code in the openshot library.
