motionblurhttps://api.pixlab.io/motionblur
Description
Simulates motion blur. The image is convolved with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. The angle parameter gives the angle of the blurring motion. This endpoint is available starting from the Prod Plan and up.
HTTP Methods
