If you didn’t close the cmd.exe dialog box just now,you can ignore this step.Or you should click “start”—“run” and input “cmd” in “Run” dialog box,then click “OK” button.Or you can use the hot key as mentioned above.

(2)Input command line

The command line contains called program,parameters,source file and target file.

htmltools.exe –xres value –yres value “input.emf” output.jpg

htmltools.exe is the called program.

–xres value –yres value are the parameters about horizontal and vertical resolution.

“input.emf”  is the source file.

output.jpg  is the target file.

"C:\Documents and Settings\admin\Local Settings\Temp\htmltools\htmltools.exe"  is the path of htmltools.exe which you can drag into cmd.exe dialog box directly.

-yres 500 -xres 700  are the values of vertical and horizontal resolution.Y indicates vertical direction while X is horizontal.

"C:\Program Files\docPrint Pro v5.0\blank.emf"  is the path of source file.Of course you can drag the file into cmd.exe dialog,too.

blank.jpg is the name of target file.You can specify the directory for the target file here such as C:\Documents and Settings\admin\Desktop\New Folder\blank.jpg.Then the file will be saved in the location C:\Documents and Settings\admin\Desktop\New Folder.
