Script to take screenshots of the desktop

Question

Programming

The task is to make a desktop application that will take screenshots of the desktop and send it to the server once a minute.
The application must be cross-platform (windows/linux/mac os).
Tell me, please, in which direction to dig. Titanium Appcelerator and Adobe Air are not offered.
Developing 3 different applications on different languages ​​is not an option.
Thanks in advance.

Answer 1

If it's a script, then python + PIL will do: effbot.org/imagingbook/imagegrab.htm
Something more compilable can be built using Qt: qt-project.org/doc/qt-5.0/qtwidgets/desktop-screenshot.html

Answer 2

> cross-platform
Here with it there can be jambs.
And so - scrot or import from ImageMagic, or one more of the darkness of screenshots ...

Answer 3

Do you have a question about choosing a cross-platform compiler, as I understand it? Then write an application in Lazarus - a simple Delphi syntax that will compile equally well under Windows, and under *nix, and under Mac OS.

Answer 4

QT, Java?
Java example stackoverflow.com/a/12807482 . I think you implement sending to the server yourself :)
