GTK/GDK Algorithm to take full screenshots of all monitors

I’m fairly new to the whole GTK game and want to create an algorithm to take screen shot of all monitors. I was thinking something along these lines: gdk_display_manager_list_displays each display can have multiple screens (screens means monitors?) so use gdk_display_get_n_screens to get monitors per display from 1 get root gtk window of all screens from 2 create new Pixbuf

Capturing high-quality(300dpi) screenshots of QT-based app in Linux

I need to make a screenshot of my form created in QT designer. There are numerous approaches to do screenshots(gimp, import, etc..) but alt of them deal with same dpi as on my monitor(about 100dpi). This is quite enough to publish on web site, but 300dpi images are required for paper publications. Are there any ways to create 300dpi screenshots?
