JPG is a image file format that can is supported on the Web. JPG is designed to compress color and grayscale continuous-tone images. For those photo images which must be very small files for web sites or email, JPG is an ideal format. In addition, JPG is often used on digital camera memory cards, for it is wonderfully small, often compressed to perhaps only 1/10 of the size of the original data.

3. Enter a command line
Please take a look at the pattern below to see which factors should be included in the command line when you rotate the page and convert WMF to JPG.
htmltools -rotate <int> <WMF file> <JPG file>
The above pattern shows that four factors are required.
- 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 ---- JPG file(s).
The following is an excellent example of the command line which should be entered in the command prompt window. It includes the mentioned four factors. However you may wonder why all the files in the example are represented by directories rather than only the file names. This is because computer will fail to recognize the files if the directories do not appear to guide it to find these files.
D:\htmltools\htmltools.exe –rotate 90 C:\in\*.wmf D:\out\*.jpg
In this example,
- 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 rclockwise 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\*.jpg is the directory of output files. The file extension indicates that the output format should be JPG. It indicates that all the output files should be export into the folder out on disk D.
All the directories in the example can be replaced with the directory of the executable file, input file and output file in your computer. The number which stands for the angle degree can also be changed, according to your priorities.
