G’day All, We are talking Mac ONLY - High Sierra and Catalina!
I found a command line application that can take a snapshot with the current camera. This nifty tool is called “imagesnap” and it is totally free in all regards. Check out: http://iharder.sourceforge.net/current/macosx/imagesnap/ <http://iharder.sourceforge.net/current/macosx/imagesnap/> So, I placed that tool in the resource folder of the application I’m working on and tried to call it from within 4D via LEP: <4D code> C_TEXT($cmd) C_TEXT($FoDoPath;$OutPictPath;$imageSnapPath) C_BLOB($StdIn;$StdOut;$Error) C_LONGINT($PID) $FoDoPath:=Get 4D folder(Current resources folder) $FoDoPath:=Convert path system to POSIX($FoDoPath) $cmd:=$FoDoPath+"./imagesnap -w 2.0 " LAUNCH EXTERNAL PROCESS($cmd;$StdIn;$StdOut;$StdOut;$PID) </4D code> Result: The camera shows activity, but no picture is saved nowhere. And now comes the voodoo I don’t get: I copied the content from “$cmd” out of the 4D-debugger and paste it into the terminal and got a jpg-picture saved into the current user account (it seems “imagesnap" has some problems with user specified destinations). The “$cmd” in my case contains this: /DATA/4Dƒ/TTTCorev18/TTTCorev18.4dbase/Resources/./imagesnap -w 2.0 Please tell me we can blame 4D for another botched implementation. Any help, pointers etc. are appreciated.
