The Image Hose344
The indexing system requires the
nozzle images to fit in a regular grid.
You can create a nozzle file by setting
up a grid and placing an image
element at the center of each cell.
Determining the Grid Cell
Size
The cell size is based on the smallest
rectangle that will hold the largest
image element (including its
selection).
To make sure your images fit in the
grid, copy your largest image element
to a layer. Refer to “Creating Layers”
on page 232 for more information.
To determine the grid cell size:
1 In the toolbox, click the Layer
Adjuster tool , and choose a
layer.
Corel Painter displays the pixel
width and height of the layer’s
content. You might want to use
slightly larger values as the grid
size.
2 Determine the number of
elements you want in each rank.
3 Multiply the number of items in
Rank-1 by the cell width.
This value is the cell width.
4 Multiply the number of items in
Rank-2 by the cell height.
This value is the cell height.
To create the grid
1 Choose File menu > New, and
enter the appropriate width and
height dimensions in the Width
and Height boxes.
2 Choose Canvas menu > Grid >
Grid Options.
3 In the Grid Options dialog box, set
the Horizontal and Vertical
Spacing to the values of the cell
width and height, and click OK.
4 Show the grid by clicking the
Toggle Grid button above the
vertical scroll bar on the image
window.
The grid should describe the
number of elements you want in
each rank—Rank 1 horizontally,
and Rank 2 vertically.
Click the Grid button to display a grid in the
image window.
Building the Nozzle
Once you have set up the nozzle
images in the grid, you can build your
nozzle.
To build a nozzle:
1 Place one image element in the
center of each grid cell.
The easiest way to do this is with
layers. Follow an appropriate
progression based on your
intentions for controlling this
nozzle. Each image element must
be included in the selection. If you
bring image elements into the grid
as layers, they will bring their layer
mask with them.
2 Choose Window menu > Show
Layers.
