Blur Filter



Blur filter blurs rendering image.



Type

Blur direction and type.

Width / Quality

Width of blur. Note that the unit of width parameter is in unit of screen coordinate, not in unit of pixel.
Blured image is obtained by overwrapping offseted images. Quality parameter determing the number of images overwrapped. Larger quality value is needed for larger width parameter.

Gamma Correction

Exactly speaking, RGB value is not the true brightness on monitor, it is modified by gamma correction. Thus, simple averaging of RGB values for overlap tends to lead darker image. When this checkbox is on, this effect is cancelled by additional correction.
