The width and height parameters specify the size of the image. Radius, offset and intensity specify the values of the variables in the vignetting function: cx = width/2; cy = height/2; r = sqrt((i-cx)*(i-cx) + (j-cy)*(j-cy)) a[i,j] = intensity * cos((r/radius) * (pi/2))) + offset The returned image is of type FLOAT
