Creating a nozzle from layers.
Creating a 2-Rank nozzle
If you want to create a 2-Rank nozzle, such as a nozzle with a two-dimensional progression, you need to
set up the nozzle images accordingly. Unlike 1-Rank nozzles, nozzles of two and three ranks cannot be
created from a layer group. You must build these nozzles manually. The indexing system requires the nozzle
images to fit in a grid. You can create a nozzle file by setting up a grid and placing an image element at the
center of each cell.
The cell size is based on the smallest rectangle that will hold the largest image element (including its
selection). To make sure that your images fit in the grid, copy your largest image element to a layer. After
you have set up the nozzle images in the grid, you can build your nozzle. For more information, see
“Creating and deleting layers” on page 520.
To determine the grid cell size and nozzle dimensions
1
In the toolbox, click the Layer Adjuster tool , enable the Auto Select Layer button on the
property bar, and in the document window click the layer with the largest image element that you want
to include in the nozzle.
Corel Painter displays the pixel width and height of the layer’s content in the Navigator panel. To display
the Navigator panel, choose Window Navigator.
You might want to use slightly larger values for the grid cell size.
Determine the number of elements that you want in each rank.
2 Multiply the number of items in Rank-1 by the cell width.
This value is the nozzle’s width.
3 Multiply the number of items in Rank-2 by the cell height.
This value is the nozzle’s height.
