Dpi

The default conversion precision

Pdf2tiffutil

public static Pdf2tiff (Is:inputstream, os:outputstream): void

Converts the specified PDF to a single TIFF file and writes to the specified output stream. parameter is provides the contents of the PDF document, the parameter OS specifies the output stream.
