试图在座标上装饰图象
原标题:trying to load bitmap image in python

我认为,我正把图像装上皮条,但我仍然 t着。 我不知道图像是否太大或什么。

import pygame
import math

pygame.display.init()
window = pygame.display.set_mode((600, 500))
mapImg = pygame.image.load("mapoftheusa.bmp")

done = False

while not done:

    window.fill((0,0,0))
    evtList = pygame.event.get()
    for evt in evtList:
         if evt.type == pygame.QUIT:
            done = True

    window.blit(mapImg, (0,0)) #<<will not blit

pygame.quit()
最佳回答

请希望在<代码>pyega.display.update(<>/code>之后添加一个电话:window.blit(mapImg, (0,0)

因此,你的完整法典应当是:

import pygame
import math

pygame.display.init()
window = pygame.display.set_mode((600, 500))
mapImg = pygame.image.load("mapoftheusa.bmp")

done = False

while not done:

   window.fill((0,0,0))
   evtList = pygame.event.get()
   for evt in evtList:
       if evt.type == pygame.QUIT:
          done = True

   window.blit(mapImg, (0,0)) #<<will not blit
   pygame.display.update() # solution: you forgot this...

pygame.quit()

<代码>pyega.display.update(>>更新了窗户(屏幕)及其图纸。 如果你坚决呼吁,你将根本看不到任何东西。 <代码>pyega.display.flip(>>)也发挥了作用,但在使用双重缓冲或硬件表面时应当加以利用。

此外,我认为最好通过打电话pyega.init()启动pyega,因为这将启动包括显示在内的所有模块。
