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 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748).
Example
This scripts sets a background on a Print section using absolute positioning.
var activeSection = merge.template.contexts.PRINT.sections['Section
1'];
activeSection.background.source = BackgroundResource.RESOURCE_PDF;
activeSection.background.url = "images/somepage.pdf";
activeSection.background.position = MediaPosition.ABSOLUTE;
activeSection.background.left = "10mm";
activeSection.background.top = "10mm";
You could replace the last three lines of the previous script by the following line to scale the
Print section background to Media size:
activeSection.background.position = MediaPosition.FIT_TO_MEDIA;
