How to set the bit depth when convertingformat file?
The right converting method can decrease much work time.There are only three steps to convertand set the bit depth for target file.Please go on reading this article.
1.If you have not closed cmd.exe dialog box just now,you can skip this step and input command line directly.If not,you should click “start”—“run” and input “cmd” in “open” edit box,then click “OK” button,or use the quick way mentioned above.

htmltools.exe –bitcount value “input.emf” output.jp2
htmltools.exe is the called program in the conversion of.
-bitcount value is the value of bit depth which you can set by yourself.
“input.emf” is the source file.
output.jp2 is the target file.
Please see the following example and you will understand the command line above better.
"C:\Documents and Settings\admin\Local Settings\Temp\htmltools\htmltools.exe" -bitcount 24 "C:\Program Files\docPrint Pro v5.0\blank.emf" blank.tga
"C:\Documents and Settings\admin\Local Settings\Temp\htmltools\htmltools.exe" is the path of htmltools.exe.The path seems too long to input or remember.Please just take the easiest way—dragging the file into cmd,exe dialog box from its folder and the file will turn to path enclosed with double quotes at once.
-bitcount 24 is the value of bit depth.
"C:\Program Files\docPrint Pro v5.0\blank.emf" is the path of source file.
blank.tga is the name of target file.
