Corel Painter 307
outside edges become thicker.
At under 100%, the edges
become finer and more deli-
cate.
• Random affects how symmetri-
cal the growth patterns appear.
Lower values generate straight-
line, geometrical designs.
Higher values generate dis-
torted, crooked designs.
• Thickness uniformly adjusts
the weight of the lines within
the design. Move the slider to
the left for thinner lines and to
the right for thicker lines. The
growth pattern never gets thin-
ner than one pixel.
• Branch determines how many
branches come from the center
to the outside edge. It has a
range of 1 through 20. The
default is 3.
•Max Level determines the
number of levels or sub-levels
that appear in the tree. Specifi-
cally, Max Level determines
how the branches split to the
outside edge.
• Fork adjusts the overall intri-
cacy of the outermost branches.
• Fork Ratio is like Fork, but it
affects only the tips of the out-
ermost branches.
5 Without closing the Growth dialog
box, drag to create a growth
pattern in the document window.
As you drag, you see the outline of
the growth pattern. When you
release, the pattern is created.
6 Do one of the following:
• To apply the current growth
pattern, click OK.
• To discard all patterns, click
Cancel.
When you click Cancel, all the
growth patterns you have created
since you opened the dialog are
deleted. It’s a good idea to click
OK to save each pattern you create.
Note
•
The sliders in the Growth dialog box
affect both fractal and non-fractal growth
patterns in a similar way, with the
exception of Fork and Fork Ratio, which
affect only fractal growth patterns.
Highpass
Highpass suppresses low frequency
areas containing gradual or smooth
transitions of brightness levels. This
leaves high frequency areas, or just the
edges of an image, containing stark
shifts between brightness levels.
The Highpass effect uses either
Gaussian or circular aperture.
Gaussian aperture affects the red,
green, and blue components of color;
circular aperture uses image
luminance.
You can make the highpass more
pronounced by using the Equalize
effect.
