使用 python 函数调整显示分辨率。应该是跨平台的,即支持windows、linux和mac(根据操作系统的不同,有多个case也是可以的)
我有我认为可以在 linux (Ubuntu) 上运行的代码 我正在寻找适用于 windows 和 mac 的解决方案(应该同时支持 32 位和 64 位机器)
def SetResolution(width, height):
os.popen("xrandr -s "+str(width)+'x'+str(height))
如果有人能告诉我如何获得 windows 和 mac 的可能显示分辨率,我将不胜感激
我在 linux 上的功能是这样的:
def GetResolutions():
screen = os.popen("xrandr").readlines()
possibleResolutions = []
for a in screen:
data = a.split()
if len(data)<4:
width, height = data[0].split('x')
fps = re.sub("[^0-9.]", "", data[1])
possibleResolutions.append({'width':int(width),'height':int(height),'fps':float(fps)})
if '*' in data[1]:
currentResolution = {'width':int(width),'height':int(height),'fps':float(fps)}
return possibleResolutions, currentResolution
最佳答案
下面是适用于 Windows 的解决方案(依赖于 pywin32)。您可以在现有的 Linux 代码中放置占位符,但我不确定如何处理 OS X。
