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