string Json()
Get and Set JSON methods.
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.
int Layer()
Get layer of clip on timeline (lower number is covered by higher numbers)
void SetJsonValue(Json::Value root)
Load Json::JsonValue into this object.
string class_name
The class name of the effect.
virtual Json::Value JsonValue()=0
Generate Json::JsonValue for this object.
bool has_audio
Determines if this effect manipulates the audio of a frame.
void SetJson(string value)
Load JSON string into this object.
Json::Value add_property_choice_json(string name, int value, int selected_value)
Generate JSON choice for a property (dropdown properties)
Json::Value add_property_json(string name, float value, string type, string memo, bool contains_point, int number_of_points, float min_value, float max_value, InterpolationType intepolation, int closest_point_x, bool readonly)
Generate JSON for a property.
string Id()
Get basic properties.
float Position()
Get position on timeline (in seconds)
string name
The name of the effect.
string PropertiesJSON(long int requested_frame)
tr1::shared_ptr< Frame > GetFrame(tr1::shared_ptr< Frame > frame, long int frame_number)
This method is required for all derived classes of EffectBase, and returns a modified openshot::Frame...
string description
The description of this effect and what it does.
float start
The position in seconds to start playing (used to trim the beginning of a clip)
virtual void SetJsonValue(Json::Value root)=0
Load Json::JsonValue into this object.
Json::Value JsonValue()
Generate Json::JsonValue for this object.
This namespace is the default namespace for all code in the openshot library.
bool has_video
Determines if this effect manipulates the image of a frame.
Exception for invalid JSON.
Deinterlace()
Blank constructor, useful when using Json to load the effect properties.
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)
EffectInfoStruct info
Information about the current effect.
