Dear all,

I need the screen capture function in my application . There are two applications (screenshot and  opensource sailshotme) in the jolla store. 

From the "sailshotme", I know that  can call the saveScreenshot method of org.nemomobile.lipstick through dbus, such as the command:

"dbus-send --session --type=method_call --print-reply --dest=org.nemomobile.lipstick /org/nemomobile/lipstick/screenshot org.nemomobile.lipstick.saveScreenshot  string:/home/nemo/Pictures/123.png "

but, using the "sailshotme" or the above mentioned command will lead to the UI blocking of sailfish system, the screen will not response within 
a few seconds, however, it seems that there is no such blocking when using the "screenshot".
so I want to know the mechanism of the "screenshot"?

Best&Regards
