I need to do a screenshot of the content of the tkinter application below. I am on Windows 7 (or 8).
from Tkinter import * def test(x): #print "I'm in event:", x if x == 1: # if event on entry e1 print 'e1 event' # do some thing elif x == 2: # also if event on entry e2 print 'e2 event' # do some thing else else: print 'no event' def test1(x): test(1) def test2(x): test(2) root=Tk() root.minsize(500,500) e1=Entry(root) e1.pack() e2=Entry(root) e2.pack() e1.bind( "<FocusOut>", test1) e2.bind( "<FocusOut>", test2) button=Button(root, text='print').pack(side=BOTTOM) root.mainloop()
Since you mentioned that you are on Windows. You can use the
Win32 API as directed in this answer Fastest way to take a screenshot with python on windows. Hope this helps.
But actually Pyscreenshot should be what you are looking for.
Take the following code for example:
from pyscreenshot import grab im = grab(bbox=(100, 200, 300, 400)) im.show()
As you can see you can use
bbox to take screenshot that is at co-ordinates (100, 200) and has a width of 300 and a height of 400.
Also as regards the printing check out Printing using win32api. I hope these help.
Using PIL you can do a resize:
from PIL import Image from pyscreenshot import grab img = grab(bbox=(100, 200, 300, 400)) # to keep the aspect ratio w = 300 h = 400 maxheight = 600 maxwidth = 800 ratio = min(maxwidth/width, maxheight/height) # correct image size is not #oldsize * ratio# # img.resize(...) returns a resized image and does not effect img unless # you assign the return value img = img.resize((h * ratio, width * ratio), Image.ANTIALIAS)
I would advise changing your program so that you can resize the image before printing
