To define variables:
1
In the Layers palette, select a layer for which you want to define variables.
Note:
You cannot define variables for the Background layer.
2
Choose Image > Variables > Define, or choose Variables from the Layers palette menu.
3
Select one or more types of variables:
•
Visibility to show or hide the content of the layer.
•
Pixel Replacement to replace the pixels in the layer with pixels from another image file.
Note:
You specify the replacement image when you define a data set. (See
“Using data
sets” on page 503
.)
•
Text Replacement to replace a string of text in a type layer.
4
If desired, enter names for the variables. Variable names must begin with a letter, under-
score, or colon and cannot contain spaces or special characters (except for periods,
hyphens, underscores, and colons).
5
For Pixel Replacement variables, click Pixel Replacement Options, and do the following:
•
Choose a method for scaling the replacement image: Fit to scale the image to fit within
the bounding box (which may leave parts of the bounding box empty); Fill to scale the
image to entirely fill the bounding box (which may cause the image to extend beyond
the bounding box); As Is to not scale the image; Conform to scale the image non-
proportionally to fit within the bounding box.
•
Click a handle on the alignment icon
to choose an alignment for placing the image
inside the bounding box.
•
Select Clip to Bounding Box to clip areas of the image that do not fit within the
bounding box. This option is only available when the Fill replacement method or As Is
replacement method is selected.
6
To define variables for an additional layer, choose a layer from the Layer pop-up menu.
Repeat Steps 3 through 5.
7
Click OK.
To rename a variable:
1
Choose Image > Variables > Define, or choose Variables from the Layers palette menu.
2
Choose the layer which contains the variable from the Layer pop-up menu.
3
Enter a name in the Name text box. Variable names must begin with a letter, under-
score, or colon and cannot contain spaces or special characters (except for periods,
hyphens, underscores, and colons).
Note:
If you are using data sets and want to rename a variable globally (in all layers),
change the name in the Data Sets section of the Variable dialog box. (See
“Using data sets”
on page 503
.)
