NAME
Prima::sys::XQuartz - MacOSX/XQuartz facilities
DESCRIPTION
XQuartz emulates X environment with certain limits, namely it cannot grab bits from the screen, and it hides top-level menu from screen coordinates accessible for X clients. For example, a Mac with 1024x768 resolution will only report f.ex. 1024x746 size to Prima. If Prima is compiled with Cocoa library, get_fullscreen_image method circumvents these limitations and returns shot of the whole screen.
Note that the screen grabbing has to be allowed. To do that, Choose Apple menu, System Preferences, click Security & Privacy, then click Privacy. Click on an icon on the left lower corner to allow changes. Then, in the screen recording tab, add XQuartz to the list of allowed applications. Note that it might not work if you run your application from a (remote) ssh session - I couldn't find how to a how to enable screen grabbing for sshd.
