InterpolationType interpolation
This is the interpolation mode.
float End()
Get end position (in seconds) of clip (trim end of video)
A Point is the basic building block of a key-frame curve.
Point GetPreviousPoint(Point p) const
Get previous point (.
int Layer()
Get layer of clip on timeline (lower number is covered by higher numbers)
bool Contains(Point p) const
Does this keyframe contain a specific point.
virtual void SetJsonValue(Json::Value root)=0
Load Json::JsonValue into this object.
Point GetClosestPoint(Point p) const
Get current point (or closest point to the right) from the X coordinate (i.e. the frame number) ...
std::string Id()
Get basic properties.
float Position()
Get position on timeline (in seconds)
Json::Value add_property_choice_json(std::string name, int value, int selected_value)
Generate JSON choice for a property (dropdown properties)
double X
The X value of the coordinate (usually representing the frame #)
Json::Value add_property_json(std::string name, float value, std::string type, std::string memo, Keyframe *keyframe, float min_value, float max_value, bool readonly, int64_t requested_frame)
Generate JSON for a property.
This namespace is the default namespace for all code in the openshot library.
Coordinate co
This is the primary coordinate.
int64_t GetCount() const
Get the number of points (i.e. # of points)
virtual Json::Value JsonValue()=0
Generate Json::JsonValue for this object.
A Keyframe is a collection of Point instances, which is used to vary a number or property over time...
float Duration()
Get the length of this clip (in seconds)
Constant curves jump from their previous position to a new one (with no interpolation).
float Start()
Get start position (in seconds) of clip (trim start of video)
