public static Bitmap Image(wnd w, RECT? r = null, CIFlags flags = CIFlags.WindowDC)

Returns

Bitmap

AuWndException Invalid w.

ArgumentException The rectangle is empty or does not intersect with the window's client area.

AuException Failed. For example there is not enough memory for bitmap of this size (width*height*4 bytes).
