Pygame——surface.blit()函数

surface.blit()函数在这个 Surface 上绘制一个源 Surface。可以使用 dest 参数定位绘图。 dest 参数可以是表示 blit 左上角位置的一对坐标，也可以是一个 Rect，其中矩形的左上角将用作 blit 的位置。目标矩形的大小不影响 blit。

Syntax : blit(source, dest, area=None, special_flags=0) -> Rect

Parameters:

• Source – Draws a source Surface onto this Surface
• dest – The draw can be positioned with the dest argument.
• area -A Rect can also be passed as the destination and the topleft corner of the rectangle will be used as the position for the blit

Python3

# import pygame module
import  pygame
  
pygame.init()
  
# width
width = 680
  
# height
height = 480
  
#store he screen size
z = [width,height]
  
# store the color
white = (255, 255, 255)
screen_display = pygame.display
  
# Set caption of screen
screen_display.set_caption('GEEKSFORGEEKS')
  
# setting the size of the window
surface = screen_display.set_mode(z)
  
# set the image which to be displayed on screen
python = pygame.image.load('bg.jpg')
  
# set window true
window = True
while window:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            window = False
              
            # display white on screen other than image
    surface.fill(white)
      
# draw on image onto another
    surface.blit(python,(50, 50))
    screen_display.update()
  
pygame.quit()
