Header file for ClipBase class.
Header file for Timeline class.
float Start() const
Get start position (in seconds) of clip (trim start of video)
float start
The position in seconds to start playing (used to trim the beginning of a clip)
float Duration() const
Get the length of this clip (in seconds)
virtual float End() const
Get end position (in seconds) of clip (trim end of video)
std::string Id() const
Get the Id of this clip object.
virtual Json::Value JsonValue() const =0
Generate Json::Value for this 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.
int layer
The layer this clip is on. Lower clips are covered up by higher clips.
float Position() const
Get position on timeline (in seconds)
virtual openshot::TimelineBase * ParentTimeline()
Get the associated Timeline pointer (if any)
float position
The position on the timeline where this clip should start playing.
float end
The position in seconds to end playing (used to trim the ending of a clip)
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 class represents a timeline.
void SortTimeline()
Sort all clips and effects on timeline - which affects the internal order of clips and effects arrays...
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).
