Question

我已经为Surface pro 4开发了一个WinJs应用程序。该应用程序以全屏模式运行，并且屏幕分辨率为2736x1824（表面分辨率）。

现在，当我在表面上启动应用程序时，DPI缩放开始起作用并且弄乱了我的布局。

有没有办法禁用该应用的缩放？

我试过了：

from Tkinter import *
import RPi.GPIO as GPIO
root = Tk()
root.geometry("320x480")
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)

GPIO.setup(18,GPIO.IN,pull_up_down=GPIO.PUD_UP)

shootdelay = 12 #12
shootinterval = 7#7
shootnumber = 5#12
videodelay = 3
selft = 5
newset = 0
endvideo = 5
intertext = "(D:" + str(shootdelay) + ")(I:" + str(shootinterval) +   ")(T:" + str(shootnumber) + ")"

flagselftim = 0  
flagvideo = 0 
videosetmode = 0 
flagsetings = 0 
flagcancel = 0  
flagnewset = 0 
secDelay = shootdelay
secInterv = shootinterval
secSelftim = selft
secvideo = videodelay
remainshots = shootnumber
secshoots = shootnumber - 1
seccompte = 0
readyshoots =

intervalometer(root)
root.mainloop()

但这似乎不起作用。

Answer 1

实际上，只为一个分辨率制作你的应用布局，特别是对于如此大的分辨率并不是一个好主意，因为该应用可以在设备上运行，例如1920x1080分辨率，即使禁用DPI缩放，你的布局也会搞砸

所以我建议让应用布局做出响应，这样每个分辨率都会正确。

Answer 2

不确定您是否仍在查看此问题，但我发现您在整个地方看到的代码实际上只是XBox（Link To Docs）

微软开发人员已经说了一段时间，这是一个基于用户的设置，他们不打算允许你使用ds（Forum Link）

您可以使用ResolutionScale（docsLink）

检测缩放值

Windows.Graphics.Display.DisplayInformation.getForCurrentView().resolutionScale

Here's a link到检测到并调整的样本。

所以你可以做什么（以及我做了什么）在需要的地方我使用css scale来调整系统以适应。我的大多数应用程序都是响应式的，所以它并不重要，但如果你使用iFrame并将其设置为1000px宽，这个比例因子实际上是1400px甚至1800px宽并完全切断..

我有调整大小事件的侦听器设置，只需根据需要进行调整。

希望有所帮助！
