Pygame: Draw app with Animation

In this simple drawing app made with pygame you will be able to draw on a black board, with just one color of one size using the mouse and the right mouse button. This is an improvement of a script I already posted this summer (2019).

You can:

• clear the screen (key c)
• save the screen in a “screenshot.png” file (key s)
• erase with right mouse button
• create an animated gif of the saved screenshot (key g)

This is a screeshot taken with the app:

Video and source code

from PIL import Image
import pygame
import glob
import os

pygame.init()
screen = pygame.display.set_mode((600,400))
pygame.display.set_caption("Trace")
clock = pygame.time.Clock()

loop = True
press = False
color = "white"
cnt = 0
[os.remove(png) for png in glob.glob("*png")]
while loop:
    try:
        #pygame.mouse.set_visible(False)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                loop = False
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_c:
                    screen.fill(pygame.Color(0, 0, 0))
                if event.key == pygame.K_s:
                    if cnt < 10:
                        pygame.image.save(screen, f"screenshot0{cnt}.png")
                    else:
                        pygame.image.save(screen, f"screenshot{cnt}.png")
                    cnt += 1
                if event.key == pygame.K_g:
                        frames = []
                        imgs = glob.glob("*.png")
                        for i in imgs:
                            new_frame = Image.open(i)
                            frames.append(new_frame)

                        # Save into a GIF file that loops forever
                        frames[0].save('animated.gif', format='GIF',
                                       append_images=frames[1:],
                                       save_all=True,
                                       duration=300, loop=0)
                        os.startfile("animated.gif")

    
        px, py = pygame.mouse.get_pos()
        if pygame.mouse.get_pressed() == (1,0,0):
            pygame.draw.rect(screen, (255,255,255), (px,py,10,10))
        if pygame.mouse.get_pressed() == (0,0,1):
            pygame.draw.rect(screen, (0,0,0), (px,py,10,10))

        if event.type == pygame.MOUSEBUTTONUP:
            press == False
        pygame.display.update()
        clock.tick(1000)
    except Exception as e:
        print(e)
        pygame.quit()
        
pygame.quit()

You can save files that will be numbered with progressive numbers. So, if you want you can save many screens to make an animated gif from png… go to this link to read how to create a gif from png files. Press “s” many times as you draw to create the animation and then press “g” as you see in the video.

Another post about making animated gif is here at this link.  There are other also, look for them in the search bar, writing gif. The following is an example of gif made with the app
