Customizing Document Conversion
The Arbortext Publishing Engine conversion processor performs a number of consecutive processing steps; each step could be customized in a number of ways to produce different results. However, all the functionality provided by the Arbortext PE sub-process can't be wrapped into a single routine.
Approach customizing the conversion process in the following ways:
You can use a built-in customization specifically for HTML output with graphics.
The conversion processor is an ACL subroutine. You can write a Java, JavaScript, or ACL custom application that calls the conversion routine from your code.
