如何在Pygame中获取屏幕某些部分的屏幕截图 [英] How to take screenshot of certain part of screen in Pygame

问题描述

有没有办法让我的pygame窗口的右半部分截屏？

Is there a way I can take a screenshot of the right half of my pygame window?

我正在使用pygame制作游戏，我需要拍摄一个屏幕快照而不是整个屏幕快照，只是右半部分。

I'm making a game using pygame and I need to take a snapshot of the screen but not the whole screen, just the right half.

我知道：

pygame.image.save(screen,"screenshot.jpg")

但这将包括图像中的整个屏幕。

But that will include the entire screen in the image.

有没有办法让我对pygame窗口的右半部分截屏？

Is there a way I can take a screenshot of the right half of my pygame window?

也许通过某种方式更改其包含的区域？我已经在Google上进行了搜索，但找不到任何我在想的东西，也许我可以使用PIL对其进行裁剪，但这似乎需要大量工作。

Maybe by changing the area that it includes somehow? I've googled it but couldn't find anything I was thinking maybe I could use PIL to crop it, but that seems like a lot of additional work.

如果不可能，谁能告诉我最简单的方法来裁剪整个屏幕的图片？

If it's not possible, can anyone tell me the easiest way for me to crop the picture of the whole screen?

推荐答案

如果您始终希望屏幕截图位于屏幕的同一部分，则可以使用 subsurface 。
http://www.pygame.org/docs /ref/surface.html#pygame.Surface.subsurface

If you always want the screenshot to be of the same portion of the screen, you could use the subsurface. http://www.pygame.org/docs/ref/surface.html#pygame.Surface.subsurface

rect = pygame.Rect(25, 25, 100, 50)
sub = screen.subsurface(rect)
pygame.image.save(sub, "screenshot.jpg")

在这种情况下，次表面可以很好地工作，因为对父表面的任何更改（屏幕）也将应用于下表面。

The subsurface would work well in this scenario because any changes to the parent surface (screen in this case) will be applied to the subsurface as well.

如果您希望能够指定屏幕的任意部分以拍摄屏幕截图（因此，每次都不是相同的矩形），那么最好创建一个新曲面，将屏幕的所需部分涂抹到该曲面上，然后保存它。

If you want to be able to specify an arbitrary portion of the screen to take a screenshot of (so, not the same rectangle every time) then it would probably be better to create a new surface, blit the desired portion of the screen to that surface, and then save it.

rect = pygame.Rect(25, 25, 100, 50)
screenshot = pygame.Surface(100, 50)
screenshot.blit(screen, area=rect)
pygame.image.save(screenshot, "screenshot.jpg")
