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 446.

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°).
