——————详细使用说明——————

mtn is a command-line program so its usage will mostly be done in a shell or command prompt. It has many options, the more frequently used ones are:

-w width : width of output image
If you want the thumbnails to have 3 columns and 10 rows, use: -c 3 -r 10
Or if you want to have 5 columns and have a shot every 65 seconds, use: -c 5 -s 65
-r rows will override -s seconds if used together
If not overridden, the defaults are used: -w 1024 -c 3 -s 120
In Windows, you can run mtn.exe from command prompt or drag files/dirs from Windows explorer and drop them on mtn.exe. You can change the default options by creating a shortcut to mtn.exe and add options there (right click the shortcut -> Properties -> Target); then drop files/dirs on the shortcut instead.
In Linux & others, you'll probably need to change the TrueType font path (-f fontfile). The default is set to tahomabd.ttf which might not exist in non-Windows systems. If you dont have a TrueType font, you can turn the text off by using -i -t.
Files which have Unicode names, e.g. in Thai Chinese Japanese Korean Greek, do work fine with mtn in both Linux and Windows (as of version 0.61). You need to tell which TrueType font to use though (-f fontfile). ARIALUNI.TTF and Cyberbit.ttf seem like good ones.

For more information, see detailed usage.
