可以根据screen_with和屏幕高度在pygame中调整对象的大小吗

import pygame

pygame.init()

screen_width = 800
screen_height = 600

screen = pygame.display.set_mode((screen_width, screen_height))

# 加载图像
image = pygame.image.load("example.png")

# 调整图像大小
scaled_image = pygame.transform.scale(image, (screen_width // 2, screen_height // 2))

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
    
    # 渲染图像
    screen.blit(scaled_image, (0, 0))
    pygame.display.flip()
