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.
| 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. |
| To create the grid |
|
| 1 | From the menu bar, choose File New, and enter the nozzle’s width and height in the Width and Height boxes. |
| You must enter the nozzle’s width and height that you calculated in steps 3 and 4 of To determine the grid cell size and nozzle dimensions. |
| 2 | From the menu bar, choose Canvas Virtual Grid Virtual Grid Options. |
| 3 | In the Grid Options dialog box, set the Horizontal spacing and Vertical spacing to the values of the cell width and height, and click OK. |
| You need to enter the cell width and height from step 1 of To determine the grid cell size and nozzle dimensions. |
| 4 | Show the grid by choosing Canvas Virtual Grid Show Virtual Grid. |
| The grid should describe the number of elements you want in each rank — Rank 1 horizontally and Rank 2 vertically. |
| To build a 2-Rank nozzle |
|
| 1 | Place one image element in the center of each grid cell. |
| Follow an appropriate progression based on your intentions for controlling this nozzle. |
| 2 | From the menu bar, choose Window Layers. |
| 3 | In the Layers panel, select all layers. |
| 4 | Click the Layer options button  , and choose Drop and Select. |
| 5 | From the menu bar, choose File Save As, and save the file in RIFF format. |
In this finished 2-Rank nozzle, variety is the first rank, and size is the second rank.
To paint with your new nozzle file, you’ll need to load it first. For more information, see To load a 1-Rank nozzle file.
