3. Enter a command line
First, you should know that in order to rotate the page and convert WMF to JP2, the command line should be composed of four factors as illustrated in the following command line pattern.
htmltools -rotate <int> <WMF file> <JP2 file>
- the executable file ---- htmltools
- the command ---- -rotate <int>, which can be used to rotate the page through the angle of 90,180, or 270 degree.( 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 ---- JP2 file(s).
Second, you’d better use directories to represent files in the command line. For instance, in the command line illustrated below, the directories rather than the bare file names appear. This is because computer will fail to recognize the file names if the directories of them do not show.
D:\htmltools\htmltools.exe –rotate 90 C:\in\*.wmf D:\out\*.jp2
- D:\htmltools\htmltools.exe is the directory of the executable file. It indicates that the executable file htmltools.exe is in the folder htmltools on disk D.
- -rotate 90 is the command that can be used to rotate the page clockwise through the angle of 90 degree. The number 90 can be substituted by 180 or 270.
- C:\in\*.wmf is the directory of the input files. The wildcard * represents all the input WMF files in the folder in on disk C.
- D:\out\*.jp2 is the directory of output files. In the example, JP2 is specified as the output format. And the whole directory indicates that all the output files should be placed in the folder out on disk D.
Can you enter the command line in the command prompt now? Why not try to replace the directories in the above example with the directories of the executable file, the input file and the output file in your computer? If it is necessary, you can also change angle degree 90.
