This class removes (i.e. keys out) a color (i.e. greenscreen)
void SetJson(const std::string value) override
Load JSON string into this object.
ChromaKey()
Blank constructor, useful when using Json to load the effect properties.
std::string Json() const override
Generate JSON string of this object.
std::string PropertiesJSON(int64_t requested_frame) const override
Json::Value JsonValue() const override
Generate Json::Value for 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...
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
This class represents a color (used on the timeline and clips)
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.
ChromaKeyMethod
This enumeration determines the algorithm used by the ChromaKey filter.
@ CHROMAKEY_BASIC
Length of difference between RGB vectors.
