The Image Hose338
Image nozzle files can be created with
one, two, or three image progressions
known as “ranks.” Corel Painter offers
these three rankings, so each nozzle
file can be identified as a 1-Rank, 2-
Rank, or 3-Rank nozzle.
The following indexing factors are
available in Corel Painter:
•None
•Velocity
•Direction
•Pressure
•Tilt
•Bearing
•Source
•Random
• Sequential
For more information about the rank
system, refer to “Designing Nozzles:
1, 2, or 3 Ranks” on page 340.
To change the indexing rule:
1 On the Stroke Designer page of
the Brush Creator, choose Image
Hose.
2 For each rank in the nozzle,
choose a rank type from the pop-
up menu.
3 If necessary, adjust the Direction
settings.
Note
•
The Rank 2 and Rank 3 types have no
effect on a 1-Rank nozzle. The rank types
are described below.
Rank Types
Sequential indexes images in the
order they appear in the rank—
moving left to right, and top down,
just as you read English.
Above: sequential indexing. Below: random
indexing.
Random selects images from the rank
at random.
Randomness can add irregularity of
color and texture to the areas you
paint with the Image Hose. This
contributes to the aesthetics of the
painting because minor irregularities
occur in natural structures.
Source delivers images based on the
luminance of pixels in the clone
source (or current pattern if you have
not set a clone source). The pixels of
the working document have a direct
correspondence with the pixels of the
clone source image. As the luminance
increases, Source delivers images from
later in the rank.
For best results, the clone source
should have the same dimensions as
the document in which you’re
working. For more information on
setting up and using a clone source,
refer to “Changing Clone Source” on
page 190.
Depending on the nozzle you’re
using, Source can be quite useful. For
example, if the source image is black
on the left and progresses through
gradations to white on the right, the
