Pygame 中的 2x2 像素表面
我正在尝试使用 pygame 开发一款 16 位时代的游戏。 我正在使用 FlashDevelop 和 Flixel，但我想尝试一些更可靠的东西。 我遇到的问题是游戏的外观，我希望屏幕中的每个像素都“更大”，我的意思是，对于 320x240 表面中的每个像素，我需要在 640x480 表面中进行 2x2 像素投影才能获得外观Frogatto 等游戏。到处询问我发现这并不像在 Flixel 中那么容易。
你们能指导我吗？
更新
我找到了一种将缩放表面传输到主表面的方法，如下所示
screenSize = width, height = 640, 480
mainScreen = pygame.display.set_mode(screenSize)
smallScreen = pygame.Surface((320, 240))
pygame.transform.scale(smallScreen, screenSize, mainScreen)
如果有人能给我一些关于这件事的最佳实践的指导，我将不胜感激。
I'm trying to develop a 16-bit-era looking game with pygame.
I was working with FlashDevelop and Flixel but I wanted to try something more solid.
The probleme I'm having is with the look of the game, I want every pixel in screen to be "bigger", I mean, for each pixel in a 320x240 surface I need a 2x2 pixel projection in a 640x480 surface to get the look of games like Frogatto. Asking here and there I found out it's not as easy as it was in Flixel.
Can you guys guide me?
Update
I figured out a way to blit a scaled surface into the main surface as follows
screenSize = width, height = 640, 480
mainScreen = pygame.display.set_mode(screenSize)
smallScreen = pygame.Surface((320, 240))
pygame.transform.scale(smallScreen, screenSize, mainScreen)
If someone could give me some pointers in best practices about this thing, I would appreciate it.

不确定您是否正在寻求有关 pygame 或如何升级 320x240 的具体建议 --> 640x480 像素...
如果是后者，那么：
有几种算法可以升级像素艺术，如 MAME 使用的 - 搜索 hq2x、hq3x、hq4x；或者查看 http://en.wikipedia.org/wiki/Hqx 或更一般的内容http://en.wikipedia.org/wiki/Pixel_art_scaling_algorithms。
对于您需要的内容可能有点偏离主题，但是 http ://research.microsoft.com/en-us/um/people/kopf/pixelart/index.html 显示了像素缩放方面的一些非常有趣的发展。
Not sure if you're asking for specific advice on pygame or how to upscale 320x240 --> 640x480 pixels...
If the latter, then:
There are a couple of algorithms to upscale pixel art, as used by MAME - search for hq2x, hq3x, hq4x; alternatively have a look at http://en.wikipedia.org/wiki/Hqx or more generally http://en.wikipedia.org/wiki/Pixel_art_scaling_algorithms.
Probably a bit off-topic for what you need, but http://research.microsoft.com/en-us/um/people/kopf/pixelart/index.html shows some really interesting developments in pixel scaling.
如果你每帧将所有各种图形绘制到位图上（就像 Flixel 所做的那样），你可以将位图的比例设置为 2.0 而不是默认的 1。
根据我对 Flixel 的了解，主类只有一个子添加到屏幕上的位图。显示的每个 flixel 对象的每一帧都会绘制到该位图。 Flixel 的比例变量只是该位图的比例。
If you draw all your various graphics onto a bitmap each frame (like what Flixel does), you can just set the scale of the bitmap to 2.0 instead of the default of 1.
From what I understand of Flixel, the main class only has one child added to the screen, a bitmap. Each flixel object that is shown is drawn each frame to that bitmap. Flixel's scale variable is just the scale of that bitmap.
