SysColor plugin 2.0.0

[jsmorley]

I notice that at least in Windows 8, there is a color that seems fundamental, but I can't see how to get it.

What I would like it to use the "title bar" color that is set in Windows 8 when you have the color scheme set to "automatic". What Windows 8 does in that case is do some evaluation of your desktop background image, and set Aero colors based on that.

What seems to be returned when I use ColorType=Aero is the color of the Windows Taskbar, which is a few shades darker than the color set for the title bar in an application.

I tried most of the other settings for ColorType, but I'm not sure Windows stores this color in any of the values.

I wonder if you ran into this Brian, and if there was any solution you saw possible?

What I would like to use as a background for a skin:

What is returned by the plugin:

3-30-2013 7-16-47 AM.jpg

So what I get when I use that color for the background of a skin (that Locate32 skin):

The difference in "darkness" is not a consistent amount that I can just add to the values returned by the plugin when I use them. While it is the same amount for each of the Red/Green/Blue values for a given color, the amount varies depending on the color of the taskbar Windows determines from the evaluation of the background. So it might be +70 each for some colors, and +40 for others.

I can get in the "ballpark" by adding +50 to each Red/Green/Blue element of the color, but it's not exact. Not a big deal, but just wondered if there is some formula Windows 8 uses, or some other value set in Windows, that might determine this.

SolidColor=([MeasureRed]+50),([MeasureGreen]+50),([MeasureBlue]+50),255

you would need a white layer on top of your base color with an opacity that corresponds with the ColorizationAfterglowBalance setting in the registry.

HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM

not sure wether they use just normal blending or a different blending mode.

this explains your +50, +70, +.. differences. hard for me to explain. better play with a white layer in Photoshop to see what effects it has on the base color.

here's a formula (alphablending section)

BANG! Thud...

"Jeff, Jeff... Oh my God!"

[moshi]

don't feel bad. i think Windows also just puts an additional layer over a base layer and let's the DWM do the compostioning. it's still an MSSTYLE after all.

Hi jsmorley and moshi,

With regards to the Automatic Aero Color issue...

Essentially, to get it from SysColor, the formula is:

Code: Select all

    R =  math.floor(( (R * (Balance) / A) + (218 * (1 - Balance)) ) % 256)
    G =  math.floor(( (G * (Balance) / A) + (218 * (1 - Balance)) ) % 256)
    B =  math.floor(( (B * (Balance) / A) + (218 * (1 - Balance)) ) % 256)

Balance is the ColorizationColorBalance key in Software\Microsoft\Windows\DWM.

For example:
Skin:

Code: Select all

[Rainmeter]
Update=1000
MiddleMouseDownAction=!RainmeterDeactivateConfig

end

It also returns two different contrasting colors for use in the skin, and saves the results in an .inc file for use in other skins.

I actually did a version of this using just the registry measure. Check it out here: http://rainmeter.net/forum/viewtopic.php?f=99&t=15015

Hope this helps,

New version of the plugin here: http://rainmeter.net/forum/viewtopic.php?p=80787#p80787

Finally, accurate Windows 8/8.1 window color is now possible with new option ColorType=WIN8!!
I recommend using it with DisplayType=RGB because it still grabs an alpha value. I could have stripped it, but I decided to just let the author do it with DisplayType. I also added some new options to get the "raw" DWM values.

Thanks DollarD for pointing me in the right direction. I did however use a different (but similar) formula.

Ohhh, my bad. Just a simple copy/paste typo (probably from when I first made the plugin).

Here are correct links (I fixed all the other links as well):
32-bit: https://github.com/brianferguson/SysColor.dll/blob/master/PluginSysColor/x32/Release/SysColor.dll?raw=true
64-bit: https://github.com/brianferguson/SysColor.dll/blob/master/PluginSysColor/x64/Release/SysColor.dll?raw=true

Thanks for reporting that!

No problem... Got'em now!

Now I have to think about what I can create using them... thanks for the update!
