var resourceUrl = 'images/policy-' + record.fields.policy + '.pdf';
merge.template.contexts.PRINT.sections['Policy'].background.url =
resourceUrl;
Positioning, scaling and rotating the background
After a background has been selected, it can be positioned, scaled and rotated, using
properties of the background object; see "background" on page1176.
To position the background, for example, set the section's background.position:
activeSection.background.position = MediaPosition.FIT_TO_MEDIA;
For all possible positions, see "MediaPosition" on page1188.
Setting a page range in script
When a PDF that serves as a dynamic section background has multiple pages, you can specify
a range of pages to be used, in a control script.
Put the number of the first page in the range in the section's background.start field and the last
page in background.end.
This requires you to set the background.allPages option to false, first. This option is true by
default and takes precedence, so when it is true, the entire PDF will be used, even if a page
range has been set.
The following script sets the page range from 2 to 5:
merge.template.contexts.PRINT.sections
['Policy'].background.allPages = false;
merge.template.contexts.PRINT.sections['Policy'].background.start =
2;
merge.template.contexts.PRINT.sections['Policy'].background.end =
5;
Tip
You could use the resource() function to check the number of pages or for example the page
height and width before setting it as a background (see "resource()" on page1160).
