Definition EffectBase.h:53
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
Definition KeyFrame.h:53
This class adjusts the saturation of color on a frame's image.
Definition Saturation.h:43
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...
Definition Saturation.h:71
Keyframe saturation_G
Green color saturation.
Definition Saturation.h:51
std::string Json() const override
Generate JSON string of this object.
Keyframe saturation_B
Blue color saturation.
Definition Saturation.h:52
Saturation()
Blank constructor, useful when using Json to load the effect properties.
std::string PropertiesJSON(int64_t requested_frame) const override
Json::Value JsonValue() const override
Generate Json::Value for this object.
Keyframe saturation_R
Red color saturation.
Definition Saturation.h:50
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
void SetJson(const std::string value) override
Load JSON string into this object.
Keyframe saturation
Overall color saturation: 0.0 = greyscale, 1.0 = normal, 2.0 = double saturation.
