This effect fills the area inside a path with a squiggly line
that simulates quick, hand-drawn shading. Shapes are automatically
converted to paths.
Note: the squiggly line is constructed like a calligraphic stroke,
that is by two almost parallel lines. This allows for variations in
line thickness. You may get better results by adding a Fill and
removing the Stroke (not automatically done by the effect).
Warning: this effect appears to make heavy demands on the CPU.
There are a great many options to control the way the hatches
are drawn. The spacing, direction, and amount of bend
are determined by on-canvas nodes, visible when the Node Tool is
in use. The other options are controlled in the Path Effect Editor
dialog. Many of the options have a random factor. One can
“re-roll the dice” by clicking on
the randomize (
) icon.
Parameters found in the dialog (see also figure below):
-
Frequency randomness: Variation of distance between hatches in percent.
-
Growth: The change in spacing between wiggles from right to left. The
last wiggle will be about a factor of the Growth
term times wider than the first wiggle.
-
Bend hatches: Determines if the hatches should be bent.
-
Magnitude jitter: 1st side: Magnitude of randomness of hatch bottom extents
(in pixels).
-
Magnitude jitter: 2nd side: Magnitude of randomness of hatch top extents
(in pixels).
-
Parallelism jitter: 1st side: Magnitude of randomness of hatch bottom positions
left to right (in pixels).
-
Parallelism jitter: 2nd side: Magnitude of randomness of hatch top positions
left to right (in pixels).
-
Half-turns smoothness: 1st side, in: How straight or curved are the right side
of the hatch bottoms (zero is straight).
-
Half-turns smoothness: 1st side, out: How straight or curved are the left side
of the hatch bottoms (zero is straight).
-
Half-turns smoothness: 2nd side, in: How straight or curved are the left side
of the hatch tops (zero is straight).
-
Half-turns smoothness: 2nd side, out: How straight or curved are the right side
of the hatch tops (zero is straight).
-
Variance: 1st side: Variation in how curved are the hatch bottoms.
-
Variance: 2nd side: Variation in how curved are the hatch tops.
-
Generate thick/thin path: Should the path vary in thickness?
-
Thickness: at 1st side: The vertical thickness of the hatch bottom (in pixels).
-
Thickness: at 2nd side: The vertical thickness of the hatch top (in pixels).
-
Thickness: from 2nd to 1st side: The horizontal thickness of the hatch going
from top to bottom (in pixels).
-
Thickness: from 1st to 2nd side: The horizontal thickness of the hatch going
from bottom to top (in pixels).
