How to run it from command line?

If your install folder is "C:\allmapsoft\umd", you can use the followed command to lauch it automatically:

C:\allmapsoft\umd\downloader.exe para1 para2 para3 para4 para5 para6 para7 para8 para9

para1: task name
para2: maps type
para3: zoom level
para4: left longitude
para5: right longitude
para6: top latitude
para7: bottom latitude
para8: path to save
para9(optional): "hide" to minimize window when download; if blank, to display window.

For example:

If you want to download an area, Google Satellite Maps(Maps type ID=1):

task name=test.umd;
maps type=1;
zoom-level=12;
left-longitude=2;
right-longitude=3;
top-latitude=49;
bottom-latitude=48;
path to save=C:\downloads

Then the command line should be:

"C:\allmapsoft\umd\downloader.exe" "test.umd" 1 12 2 3 49 48 "C:\downloads"

if you want to hide the window, please use:

"C:\allmapsoft\umd\downloader.exe" "test.umd" 1 12 2 3 49 48 "C:\downloads" hide

After downloading, you can also run combiner.exe from command line mode:

"C:\allmapsoft\umd\combiner.exe" para1 para2 para3
