I'm looking for a way to take screenshots either with some utility or programmatically using API. The application I'm using has that functionality (written in Java, AWT library) but it doesn't work since WebOS seem to be using Wayland, and not X11. The following error is logged:
java.awt.AWTError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.
I also considered using Xwayland in order to have X11 compatible interface, though couldn't find any related information and if capturing screenshots is possible with it.
Thanks for your response.
And what wayland compositor is used now in webOS OSE? And are there any plans to implement screenshot functionality in it?
As I understand there's no use in installing xwayland as wayland doesn't have screenshot API anyway?
Thank you for the luna-send command. It works on WebOSE 1.0 build for raspbery3.
Unfortunately the build for raspbery4, I got in http://build.webos-ports.org/webosose/
returns "errorText": "com.webos.surfacemanager is not running.".
I'll be very grateful if someone let me now how to get capturescreen?
