Corel Painter 339
Image Hose delivers images from the
start of the rank at the left of the
document, in the dark area. As the
brush moves to the right into the
lighter area, the Image Hose delivers
images from later in the rank.
To take advantage of this feature, you
may want to create a special source
image for the single purpose of
controlling the Image Hose.
The clone source image or pattern for
controlling the Image Hose may be
grayscale. Remember, Corel Painter
uses only the luminance values.
Indexing based on Source.
Bearing indexes images based on the
position of the stylus. Not all stylus
models convey this information. This
control does not work with a mouse.
Tilt indexes images based on the tilt of
the stylus. Not all stylus models
convey this information. This control
does not work with a mouse.
Pressure indexes images based on
stylus pressure. Greater pressure
selects images from later in the rank.
Pressure works only with pressure-
sensitive tablets.
Pressure is a great control for
requesting images from a nozzle. For
example, if you set up your nozzle file
to progress from small to larger
images, heavier strokes deliver larger
images.
Direction indexes images from the
rank based on the direction of the
stroke. The first item in the rank
matches to a left-right stroke (toward
3 o’clock). As the stroke direction
progresses counter-clockwise, the
Image Hose delivers subsequent
images from the rank.
The number of elements in the rank
determines the directional change
required to index a different element.
For example, a nozzle file that
contains 72 images at progressive
angles delivers a different item at
every 5° of stroke direction (360°/
72=5°).
This Arrow nozzle is an example of indexing
based on Direction.
Ve lo ci t y indexes images from the rank
based on the speed of the stroke. A
faster stroke delivers elements from
later in the rank. Velocity is often used
with a mouse to mimic pressure.
Velocity can be difficult to control. For
this reason, you might want to use it
in a rank with few elements.
None returns one element only— the
last in the rank.
