Image hose 443

The indexing rules for Rank 2 and Rank 3 have no effect on a 1-Rank

nozzle.

Understanding nozzles, ranks, and indexing

You can create custom nozzles for the Image hose by choosing a series of images and

then applying ranks and indexing rules. After saving a custom nozzle, you can load it

so you can use it in an image. For more information, see “Loading and managing nozzle

files” on page 452.

You can create a simple nozzle (1-Rank) or, as your Image hose requirements become

more exacting, you can create complex nozzles (2-Rank or 3-Rank) that involve two

or three progressions — for example, images getting larger and changing angle. In this

case, you’ll use one input factor to determine image size and use another factor to

determine image angle.

Introducing the rank indexing system

A 1-Rank indexing system is simply a numbered sequence. You can locate any element

in the sequence by specifying its number — for example, “Item 3.”

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 that is located where the selected

column and row intersect. For this to work properly, you must use different indexing

rules (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. You must use different indexing rules for selecting in each

rank.

A 3-Rank indexing system can be used with calendar dates. Any day — past, present,

or future — can be located by specifying 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

1 2 ... 461 462 463 464 465 466 467 468 469 470 471 ... 942 943
