101 std::shared_ptr<Frame>
GetFrame(std::shared_ptr<Frame> frame, int64_t frame_number);
105 void SetJson(std::string value);
void SetJson(std::string value)
Load JSON string into this object.
This abstract class is the base class, used by all effects in libopenshot.
Json::Value JsonValue()
Generate Json::JsonValue for this object.
bool replace_image
Replace the frame image with a grayscale image representing the mask. Great for debugging a mask...
void Reader(ReaderBase *new_reader)
Set a new reader to be used by the mask effect (grayscale image)
std::shared_ptr< Frame > GetFrame(std::shared_ptr< Frame > frame, int64_t frame_number)
This method is required for all derived classes of EffectBase, and returns a modified openshot::Frame...
This abstract class is the base class, used by all readers in libopenshot.
ReaderBase * Reader()
Get the reader object of the mask grayscale image.
Keyframe contrast
Contrast keyframe to control the hardness of the wipe effect / mask.
Mask()
Blank constructor, useful when using Json to load the effect properties.
This class uses the image libraries to apply alpha (or transparency) masks to any frame...
std::string Json()
Get and Set JSON methods.
This namespace is the default namespace for all code in the openshot library.
void SetJsonValue(Json::Value root)
Load Json::JsonValue into this object.
Keyframe brightness
Brightness keyframe to control the wipe / mask effect. A constant value here will prevent animation...
A Keyframe is a collection of Point instances, which is used to vary a number or property over time...
