How to rotate the page when converting WMF to PNM?

Step 3: Type a command line

Once the command prompt window appears, you can type a command line. First you should know the command line should consist four items:

  • The executable file ---- htmltools. It is the main executable file of VeryPDF HTML Converter Command Line.
  • The command ---- -rotate <int>. int refers to integer and the angle brackets <> are often used to mark the essential content.
  • The input file ---- WMF file(s)
  • The output file ---- PNM file(s)

In conclusion, the form of the command line should be like the following.

htmltools -rotate <int> <WMF file> <PNM file>

Second, when you type a command line, make sure that all the files are represented by the directories rather than only their file names. This is because computer can seldom recognize the bare file names in a command line if the directories are not provided. The following is an example which can be used to batch convert WMF to PNM and rotate the page.

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

  • D:\htmltools\htmltools.exe ---- the directory of the executable file. In the example, it displays that the executable file htmltools.exe is located in the folder htmltools on disk D.
  • -rotate 90 ---- the command that can be used to rotate the page clockwise through an angle of 90 degree. The number 90 can be substituted by 180 or 270.
  • C:\in\*.wmf ---- the directory of the input files. The wildcard * represents all the input WMF files in the folder in on disk C.
  • D:\out\*.pnm---- the directory of output files. The file extension specifies PNM as the output format. It indicates that all the result files must be saved in the PNM format and should be placed in the folder out on disk D.

All the directories of the files in the example are allowed to be replaced, depending on the circumstances on your computer. Besides, the number which stands for the angle degree can also be changed, according to your priorities.

Step 4: Press “Enter”

As you press “Enter” on the keyboard, the computer begins to convert WMF to PNM in batch. Meanwhile, the command prompt window will display the conversion time and process of conversion. The following prompt is the command prompt window with the example command line and the process information.
