Overview

The operation allows to export document pages to the image files with given DPI, zoom factor and specified format.

Parameters

Name Type Description
Input Array Array of IUnknown-based objects.
Output Array Array of IUnknown-based objects.
Options Dictionary Dictionary with options of the operation.
