To randomize the spacing between Image hose elements

• On the property bar, move the Stroke Jitter slider to the right.

Indexing nozzle files

A nozzle file can contain any number of images. Usually, the images are similar and form a logical series —

that is, the images progress along some order. For example, the images might increase in size or advance

in angle. It is not necessary for images to progress in a logical series, but the Image hose is more effective

when they do.

“Indexing” refers to the method used to select particular images from the many images in a nozzle file.

You can apply indexing rules to control the sequencing of nozzle images. For example, you can set up the

nozzle so that by pressing harder with a pressure-sensitive stylus, you paint with larger images.

Ranks and indexing rules

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. For more information, see “Creating a 1-Rank nozzle” on page 479.

The following indexing rules are available for each rank in Corel Painter:

• None returns one element only — the last in the rank.

• Velocity 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.

• Direction indexes images from the rank based on the direction of the stroke. The first item in the

rank corresponds to a left-to-right stroke (toward 3 o’clock). As the stroke direction progresses

counterclockwise, 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° divided by 72 equals 5°).

This Arrow nozzle is an example of indexing based on Direction.

• 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
