使用python截取屏幕截图

当我将它作为控制台应用程序运行时，下面的代码工作正常

import gtk.gdk import time w = gtk.gdk.get_default_root_window() sz = w.get_size() print "The size of the window is %dx %d" % sz pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False,8,sz[0],sz[1]) pb = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,sz[0],sz[1]) ts = time.time() filename = "screenshot" filename += str(ts) filename += ".png" if (pb != None): pb.save(filename,"png") print "Screenshot saved to "+filename else: print "Unable to get the screenshot." 

但是现在我在ubuntu应用程序中使用它时（使用快速和glade）它给了我错误消息

  WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-O1o56xxlHA: Connection refused /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: specified class size for type `PyGtkGenericCellRenderer' is smaller than the parent type's `GtkCellRenderer' class size from gtk import _gtk /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed from gtk import _gtk 

如何改进此代码以在基于GUI的应用程序中工作

编辑我做了什么来改变代码

 from gi.repository import Gdk, GdkX11, Gtk w = Gdk.get_default_root_window() geo = w.get_geometry() pb = GdkPixbuf.Pixbuf.new(GdkPixbuf.Colorspace.RGB,False,8,geo[2],geo[3]) pb = pb.gdk_pixbuf_get_from_window(w,0,0,geo[2],geo[3]) pixbuf = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,geo[2],geo[3]) pixbuf.save("xdfgxfdgdfxgfdx.png","png") print "The size of the window is %dx %d" % sz pix = GdkPixbuf.Pixbuf.gdk_pixbuf_get_from_window(root_window, 0, 0, 500, 500) pix = GdkPixbuf.gdk_pixbuf_get_from_window(window,0,0,500,500); ts = time.time() filename = "screenshot" filename += str(ts) filename += ".png" if (pix != None): pix.save(filename,"png") print "Screenshot saved to "+filename else: print "Unable to get the screenshot." 

但它仍然给我错误

 (0, 0, 1366, 768)  Traceback (most recent call last): File "/home/srs/projectob-team/projectob_team/SelectmemoDialog.py", line 63, in on_start_clicked pb = pb.gdk_pixbuf_get_from_window(w,0,0,geo[2],geo[3]) AttributeError: 'Pixbuf' object has no attribute 'gdk_pixbuf_get_from_window'

使用PyGobject（Quickly使用的Gtk版本）获取屏幕截图的正确方法是：

 from gi.repository import Gdk window = Gdk.get_default_root_window() x, y, width, height = window.get_geometry() print("The size of the root window is {} x {}".format(width, height)) # get_from_drawable() was deprecated. See: # https://developer.gnome.org/gtk3/stable/ch24s02.html#id-1.6.3.4.7 pb = Gdk.pixbuf_get_from_window(window, x, y, width, height) if pb: pb.savev("screenshot.png", "png", (), ()) print("Screenshot saved to screenshot.png.") else: print("Unable to get the screenshot.") 

您发布的第一个版本是旧版PyGtk。 所以它适用于控制台，因为它只加载PyGtk。 在Quickly应用程序中，PyGobject已加载，您无法加载它们。 你一直在寻找get_from_drawable（），见：
