Nozzle Options
The Nozzle Selector has one option
for the Image Hose—Use Brush Grid.
When Use Brush Grid is enabled, the
Image Hose places images in a regular
grid pattern. The grid size follows the
grid in the nozzle file.
Enable Use Brush Grid to place images on a
perfect grid.

The Nozzle Ranking System
A 1-Rank indexing system is simply a
numbered sequence. You can locate
any element in the sequence by giving
its number. For example, “Item 3.”
In Corel Painter, you locate and
deliver images by varying input—for
example, by pressing harder with the
stylus or changing the direction of the
stroke. For information on the input
factors you can use to control
indexing, refer to “Scale” on page 337.
A 2-Rank indexing system uses two
perpendicular indexes. The first rank
extends horizontally and the second
extends vertically. Again, you’ll vary
input to locate an item for either rank.
You can think of indexing in the two
ranks as “selecting a column” and
“selecting a row.” The Image Hose
delivers the image from the nozzle
where the selected column and row
intersect. For this to work properly,
you must use different input factors
for selecting in each rank.
A 3-Rank indexing system extends the
2-Rank model. The third rank is
created by repeating the 2-Rank “set.”
Within the selected set, the 1-Rank
and 2-Rank indexing (described
above) is used. In order for this to
work properly, you must use different
input factors for selecting in each
rank.
A 3-Rank indexing system can be used
with calendar dates. Any day, in the
past or future, can be located, given
the month, day, and year. For example,
“February 25, 1962 (2/25/1962).”
Designing Nozzles: 1, 2, or 3
Ranks
A nozzle file contains a series of
images arranged in a regular grid.
Usually, the images are progressive in
terms of size, shape, angle, or color.
Progression is not necessary, but it
increases the sophistication of the
Image Hose. For example, a nozzle
file with images progressing in size
can be set up so that greater stylus
pressure paints incrementally larger
images.
A 1-Rank Nozzle progresses in one dimension.
In this example, changing angle is the first
rank.
What if you want a two-dimensional
progression, such as having image
elements increasing in size and
