PDFspy is the ultimate “get info” utility for your PDF documents. It can extract a comprehensive list of attributes from a PDF file into an XML-based format.
PDFspy extracts information about each page in a PDF and creates an XML report. XSLT Transform element uses a stylesheet to convert XML into a formatted preflight report organized by page.
The flow uses Apago's PDFspy to examine the contents of a PDF and determine if it contains color or black-only elements.
