+
+==== Padding ====
+
+The function ''padding_set'' can be used to forcily set a specific padding for this filter, regardless of the other operations.
+
+== Syntax ==
+<code Lua>
+padding_set ({ l, r = [l], t = [r], b = [t] })
+</code>
+
+== Parameters ==
+|''l'' |Padding on the left side in pixels. |
+|''r'' |Padding on the right side in pixels. If unset, defaults to ''l''. |
+|''t'' |Padding on the top in pixels. If unset, defaults to ''r''. |
+|''b'' |Padding on the bottom in pixels. If unset, defaults to ''t''. |
+
+All values must be >= 0. When filtering 'filled' images, some values may be too high and would result in completely hiding the image.
+
+It is not possible to set only one of those without forcing the others as well. A common use case will be when changing a blur size during an animation, or when applying a mask that will hide most of the (blurred) text.
+
+== Example ==
+This will set the left, right, top and bottom paddings to their respective values, and some effects may look like they've been "clipped" out.
+<code Lua padding_set.lua>
+fat = buffer ('alpha')
+padding_set ({ l = 10, r = 20, t = 15, b = 25 })
+fill ({ color = 'black' })
+fill ({ color = 'darkblue', l = 2, r = 2, t = 2, b = 2 })
+grow ({ 30, dst = fat })
+blur ({ 40, src = fat, color = 'white' })
+blend ({ color = 'darkblue' })
+</code>
