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