Apply a motion blur to your layer
This filter adds a directional blur to the provided ggplot layer. The amount of blur, as well as the angle, can be controlled.
with_motion_blur(x, sigma = 0.5, angle = 0, ...)
x |
A ggplot2 layer object, a ggplot, a grob, or a character string naming a filter |
sigma |
The standard deviation of the gaussian kernel. Increase it to apply more blurring. If a numeric it will be interpreted as given in pixels. If a unit object it will automatically be converted to pixels at rendering time |
angle |
Direction of the movement in degrees (0 corresponds to a left-to-right motion and the angles move in clockwise direction) |

Arguments to be passed on to methods. See the documentation of supported object for a description of object specific arguments. |
Depending on the input, either a grob, Layer, list of Layers,
guide, or element object. Assume the output can be used in the same
context as the input.
