Convert slides 2 through 5 of a PowerPoint file, C:\PowerPoint\Semi.ppt, to a single PDF format file named C:\PPTOutput\SemiPDF.pdf. Verbose mode invoked for on-screen confirmation. Use the following syntax:
ConvertPPT /S "C:\PowerPoint\Semi.ppt" /T "C:\PPTOutput\SemiPDF.pdf" /Y2 /Z5 /C300 /V
Note that Advanced PDF options cannot be set from the command line (e.g. Page and Document Settings, Paragraph Formatting, Font, etc.). They must be set in the user interface prior to using the command line.
It is highly encouraged that you use the Verbose (/V) switch initially to see what the status of your conversion is.
