D:\htmltools\htmltools.exe -rotate 90 C:\in\*.wmf D:\out\*.pdf

  • D:\htmltools\htmltools.exe ---- the directory of the executable file htmltools.exe. Usually, the executable file htmltools.exe is placed in the folder htmltools when the compressed file is decompressed. In the example, the directory represents the executable file htmltools.exe, which is in the folder htmltools on disk D.
  • -rotate 90 ---- the command that can be used to rotate the page clockwise. It specifies 90 as the angle degree. The number can be replaced by 180 or 270.
  • C:\in\*.wmf ---- the directory of the input files. The wildcard * in this directory represents all the input WMF files in the folder in on disk C.
  • D:\out\*.pdf ---- the directory of output files. The file extension pdf indicates that the output format should be PDF. The whole directory tells the computer to put all the result files in the folder out on disk D.
