15.4.6 Slur
15.4.6.1 Overview
Figure 15.74: Example of applying the Slur filter
(a) Original image (b) Filter Slur applied
You can find this filter through Filters → Noise → Slur.
Slurring produces an effect resembling melting the image downwards; if a pixel is to be slurred, there is an 80% chance that
it is replaced by the value of a pixel directly above it; otherwise, one of the two pixels to the left or right of the one above is
used. All or only some pixels in an active layer or selection are affected, the percentage of affected pixels is determined by the
Randomization (%) option.

Random Seed Random Seed controls randomness of slurring. If the same random seed in the same situation is used, the filter
produces exactly the same results. A different random seed produces different results. Random seed can be entered
manually or generated randomly by pressing New Seed button.
When the Randomize option is checked, random seed cannot be entered manually, but is randomly generated each time
the filter is run. If it is not checked, the filter remembers the last random seed used.
