问题描述

你如何使用来吸引你的松鼠:

所以，归结为——DwmGetColorizationColor 是完全无法用于尝试的应用程序将当前颜色应用到不透明的表面.

我喜欢、糟糕、坏，并且可以随时离开)

使用未记录的注册表项(这也是坏，并且可以随时消失)

检索用于不透明表面渲染的 Aero Glass 基色

我想问这个问题已经一年多了.我一直都知道这是不可能回答的，让任何人真正关注的唯一方法就是拥有彩色屏幕截图；开发人员被闪亮的东西所吸引.但不利的一面是，这意味着我不得不投入各种工作来制作诱饵.

解决方案

Colorization color != 选择的基色.这是误导，我知道.

但是我很困惑.您借用的图片来自我的帖子，标题为检索用于不透明表面渲染的 Aero Glass 基色".这不是你想做的吗?我还在帖子中指出了存储所有颜色信息的注册表位置 (HKEY_CURRENT_USERSoftwareMicrosoftWindowsDWM) 以供检索.

8 月 26 日编辑

DwmGetColorizationColor (dwmapi.dll) 返回着色颜色"，它是各种颜色(包括您选择的基色)和着色器逻辑的混合，以实现整体玻璃效果.

您需要/想要的所有颜色信息都可以在上述注册表项中找到.基色、混合使用的颜色以及最终的着色颜色都在那里.

(上述密钥存在于 Windows Vista 及更高版本上.)

How do you use DwmGetColorizationColor?

The documentation says it returns two values:

a 32-bit 0xAARRGGBB containing the color used for glass composition
a boolean parameter that is true "if the color is an opaque blend" (whatever that means)

Here's a color that i like, a nice puke green:

You can notice the color is greeny, and the translucent title bar (against a white background) shows the snot color very clearly:

i try to get the color from Windows:

DwmGetColorizationColor(dwCcolorization, bIsOpaqueBlend);

And i get

dwColorization: 0x0D0A0F04
bIsOpaqueBlend: false

According to the documentation this value is of the format AARRGGBB, and so contains:

AA: 0x0D (13)
RR: 0x0A (10)
GG: 0x0F (15)
BB: 0x04 (4)

This supposedly means that the color is (10, 15, 4), with an opacity of ~5.1%.

But if you actually look at this RGB value, it's nowhere near my desired snot green. Here is

(10, 15, 4) with zero opacity (the original color), and
(10,15,4) with 5% opacity against a white/checkerboard background:

Rather than being Lime green, DwmGetColorizationColor returns an almost fully transparent black.

So the question is: How to get glass color in Windows Vista/7?

i tried using DwmGetColorizationColor, but that doesn't work very well.

A person with same problem, but a nicer shiny picture to attract you squirrels:

i love this guy's screenshots much better than mine. Using his screenshots as a template, i made up a few more sparklies:

For the last two screenshots, the alpha blended chip is a true partially transparent PNG, blending to your browser's background. Cool! (i'm such a geek)

Edit 2: Had to arrange them in rainbow color. (i'm such a geek)

Edit 3: Well now i of course have to add Yellow.

Undocumented/Unsupported/Fragile Workarounds

There is an undocumented export from DwmApi.dll at entry point 137, which we'll call DwmGetColorizationParameters:

HRESULT GetColorizationParameters_Undocumented(out DWMCOLORIZATIONPARAMS params);

struct DWMCOLORIZATIONPARAMS
{
   public UInt32 ColorizationColor;
   public UInt32 ColorizationAfterglow;
   public UInt32 ColorizationColorBalance;
   public UInt32 ColorizationAfterglowBalance;
   public UInt32 ColorizationBlurBalance;
   public UInt32 ColorizationGlassReflectionIntensity;
   public UInt32 ColorizationOpaqueBlend;
}

We're interested in the first parameter: ColorizationColor.

We can also read the value out of the registry:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsDWM
    ColorizationColor: REG_DWORD = 0x6614A600

So you pick your poison of creating appcompat issues. You can

rely on an undocumented API (which is bad, bad, bad, and can go away at any time)
use an undocumented registry key (which is also bad, and can go away at any time)
