This abstract class is the base class, used by all effects in libopenshot.
Keyframe iterations
Iterations keyframe. The # of blur iterations per pixel. 3 iterations = Gaussian.
This namespace is the default namespace for all code in the openshot library.
This class adjusts the blur of an image, and can be animated with openshot::Keyframe curves over time...
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
Keyframe vertical_radius
Vertical blur radius keyframe. The size of the vertical blur operation in pixels.
Keyframe horizontal_radius
Horizontal blur radius keyframe. The size of the horizontal blur operation in pixels.
Keyframe sigma
Sigma keyframe. The amount of spread in the blur operation. Should be larger than radius.
