Hello, and thank you for showing your interest in Chameleon!
If you like this plugin, please consider donating via PayPal to help fund further features!
This is a simple plugin that will sample colors from an image allowing your skins to seamlessly blend in with the user's wallpapers with minimal setup!
Chameleon can be used with more than just wallpapers, though! With certain options, you can pass it any file you chose and it will do it's best to grab some colors from it.
Currently it supports the following formats directly:
- BMP (non-RLE, non-1bpp)
- GIF (just like Rainmeter, first frame only)
- Some PSDs
- HDR (radiance rgbE format)
- PIC (Softimage PIC)
- PNM (PPM and PGM binary only)
Anything else, and it'll grab the icon and use the colors from that. This does mean that it also supports .ico and .exe icon sampling! Sampling from icons is a bit roundabout, check out the FileView plugin for how to get them from a .exe.
If you're downloading this from my site, installing Chameleon is as simple as installing the example .rmskin. Rainmeter will stash everything where it's supposed to go for you. If you're grabbing this from GitHub you'll also need to grab the libChameleon repo and tell Visual Studio where that's built at. From there, compilation should be fairly straightforward. Then you just need to toss the apropriate architecture's DLL into the Rainmeter plugin folder in your AppData's Roaming profile folder.
If you want to build the libChameleon test app you'll need to grab it's repo. It only depends on wxWidgets and libChameleon.
Using Chameleon is really simple! You can set it to either sample from the desktop or directly from a specific image. If you set it up to sample from the desktop, it'll automatically pick the wallpaper for the monitor that the skin is currently on.
You'll need a parent measure, which tells Chameleon what image you'll be sampling from, and a set of child measures that tell Chameleon which colors you're interested in.
For the parent measure you can set either
If you set the type as
File you'll need to specify
as well. This can be the output of another measure!
Optionally you can tell Chameleon to always sample from a file
as an icon using the
ForceIcon parameter (such as if you
have a .png version of an icon).
You can also optionally tell Chameleon whether you want these
values as a hex code or a numeric color code by setting the
Format option to
You might find it useful to only grab colors from a cropped
region of an image. You can do so with the
CropH options. These set the position and
dimension of the rectangle to crop out.
By default, Chameleon will attempt to crop desktop images to
the visible portion based on the monitor's resolution. You
can tell Chameleon to not do this by setting
CropDesktop to 0.
One last optional option is to tell Chameleon what fallback
colors to use when it just can't sample from an image (such
as with the NowPlaying measure's album art). Right now this
can only be specified in hex, and should not include the
alpha value. You can specify this with
XYZ is one of
FG2 for it's
Parent measures also offer the super-sneaky bonus of returning the path of the image it's sampling from!
For the child measures you'll need to specify
tell Chameleon which measure you're getting the colors from,
Color which tells Chameleon which color you're interested
Dark colors are just the selected foreground and
background colors sorted by how light or dark they are, respectively.
Color can be one of:
Averagewhich is the overall average color of the image
Luminancewhich is not a color, but rather a floating point value between 0 and 1 indicating the average luminance of the image.
Here's an example:
[ChameleonDesktop] Measure=Plugin Plugin=Chameleon Type=Desktop [DesktopBG1] Measure=Plugin Plugin=Chameleon Parent=ChameleonDesktop Color=Background1
In this case,
[ChameleonDesktop] would return the wallpaper
the skin is currently sitting on, and
return the color Chameleon thinks is the main background.
Chameleon does not add an alpha value to the color codes!
You'll need to add this yourself to tell Rainmeter how
transparent you want the color. By default, just adding
FF after wherever you use the measure value works.
Another case users might be interested in is having a meter colored based on the NowPlaying album art image. This is super easy to set up too!
[ChameleonFile] Measure=Plugin Plugin=Chameleon Type=File Path=[NowPlayingAA]
That's it! Everything else will automatically update, as long as you've set DynamicVariables=1 on the apropriate meters.
