This article "python how to achieve gif screencap function" most people do not understand, so the editor summed up the following content, detailed, clear steps, with a certain reference value, I hope you can get something after reading this article, let's take a look at this "python how to achieve gif screencap function" article.

1. Realization of the main interface

(1) implement the simplest form from tkinter import * if _ _ name__ ='_ _ main__': tk = Tk () tk.geometry ('500x400' 500 '150') tk.title ('interesting transparent form-here we go!') Canvas = Canvas (tk) canvas.pack (fill=BOTH, expand=Y) tk.mainloop ()

It's too easy. I don't want to go into details. I believe everyone can understand it.

(2) set gray to transparent color TRANSCOLOUR = 'gray'tk.wm_attributes ('-transparentcolor', TRANSCOLOUR) (3) place a rectangular box on canvas canvas.create_rectangle (0,0, canvas.winfo_width (), canvas.winfo_height (), fill=TRANSCOLOUR, outline=TRANSCOLOUR) (4) onsize function def on_resize (evt): tk.configure (width=evt.width,height=evt.height) canvas.create_rectangle (0,0, canvas.winfo_width ()) Canvas.winfo_height (), fill=TRANSCOLOUR, outline=TRANSCOLOUR) print (canvas.winfo_width ()) (V) bind onsize function tk.bind ('', on_resize) II. Implementation of GIF screencap function

(1) Save each time as a picture def _ GifScreen (): global i i + = 1 HWND = win32gui.FindWindow (None,' interesting transparent form-start!') Print (HWND) rect=win32gui.GetWindowRect (HWND) # get the coordinates of the current window rect= (rect [0] + 10 rect rect [1] + 32 10+canvas.winfo_height [0] + 10 recording canvas.winfol (), rect [1] + 10+canvas.winfo_height () + 16) print (rect) im=ImageGrab.grab (rect) # capture the target image im.save (". / out/CaptureScreen_%s.jpeg"% iParticipjpeg') # the first parameter is to save the path The latter parameter is the save format (2) enable a thread

Enable a thread and call the makegif function to intercept gif images.

Def GifScreen (): thread_list = [] T1 = threading.Thread (target=makegif) thread_list.append (T1) (3) implement specific makegif functions

When the number of images generated reaches 20, the create_gif function is called to package the gif file.

Def makegif (): global I imagewriting list while True: _ GifScreen () time.sleep (0.5) if I > 20: break Create_gif (image_list,'out.gif',0.5) (IV) implementation of create_gif Package the pictures in the folder into a GIF file image_list = [] def create_gif (image_list, gif_name, duration= 1.0): frames = [] for image_name in image_list: frames.append (imageio.imread (image_name)) imageio.mimsave (gif_name, frames, 'GIF', duration=duration) (V) add screencap button And bind the response event GifScreenb = Button (tk, text='GIF screenshot' Command=GifScreen) b.pack () (6) implement the button's response event GifScreendef GifScreen (): thread_list = [] T1 = threading.Thread (target=makegif) thread_list.append (T1) # officially start the current thread for t in thread_list: t.setDaemon (True) t.start () above is the content of this article on "how python implements gif screencap" I believe we all have a certain understanding.
