Following the executable file is the command -rotate <int>, which can be used to rotate pages. The angle brackets are used to mark the essential content. int means integer. This command permits three parameter values, which are 90, 180, and 270. After the command are <HTML file> and <PDF file>, which present input HTML file(s) and output PDF file(s) respectively.

Step 2: Enter a command line

Taking the following command line as an example, the whole directories of the files, rather than only the names of the files, must appear in the command prompt window. This is because that the directories can lead the computer to find the place where the files are store in.

D:\htmltools\htmltools.exe -rotate 90 D:\in\*.html D:\out\*.gif

  • D:\htmltools\htmltools.exe ---- the directory of the executable file htmltools.exe. In the example, the directory shows that the executable file is in the folder htmltools on disc D. The example directory can be replaced by the actual directory of the executable file in your computer.
  • -rotate 90 ---- the command for rotating pages. It specifies 90 as the angle degree. The number can be replaced by 180 or 270.
  • D:\in\*.html----the directory of the input files. The wildcard * stands for all the web pages in the folder in on disk D.
  • D:\out\*.gif---- the directory of output files. The file extension gif in the command line indicates that the output format should be GIF. Again, the wildcard * represent all the output files in the folder out on disk D. Both the directories of the input and output files can be substituted.

Step 3: Press “Enter”

Click “Enter” on the keyboard, and the computer will batch convert HTML to GIF without delay. In a few seconds, you can view the effect of the output GIF files in the selected output folder.
