我想在pygame中绘制一条(任意位置和长度)的线条,它本身就是从磁盘上的文件加载的图像。
有人能指出我这样做的一些示例代码吗?

这应该做你要求的:
# load the image
image = pygame.image.load("some_image.png")
# draw a yellow line on the image
pygame.draw.line(image, (255, 255, 0), (0, 0), (100, 100))
通常,您不会绘制到原始图像,因为您必须重新加载图像才能获得原始图像(或者在开始绘制图像之前创建它的副本)。也许你真正需要的是更像这样的东西:
# initialize pygame and screen
import pygame
pygame.init()
screen = pygame.display.set_mode((720, 576))
# Draw the image to the screen
screen.blit(image, (0, 0))
# Draw a line on top of the image on the screen
pygame.draw.line(screen, (255, 255, 255), (0, 0), (50, 50))
