CursorColor

jsmorley » May 28th, 2016, 4:49 pm

Demonstrates a new ColorCursor 3rd-party plugin.

Retrieves the color of the pixel under the cursor when you fire the measure with !CommandMeasure. I would expect this to generally be on a mouse click action.

Must be called with:
[!CommandMeasure MeasureName "GetColor"]

Only option is "Format", which can be RGB/Red/Green/Blue.

The plugin is included in the .rmskin, as are the plugin 32bit and 64bit .dll files, for use in your .rmskin..
CursorColor_1.0.rmskin
Or just the plugin 32bit and 64bit .dll files, for use in your .rmskin.

I was waiting for this plugin two years. Now I have to stop procrastinating and make a color picker based on your plugin merged with another handy tool developed by dgrace and reimagined by you https://forum.rainmeter.net/viewtopic.php?p=117322#p117322

Sorry to gravedig!

Would it be possible to amend this plugin so that rather than just getting the color and creating a preview of the desktop at the cursor position, you could instead get the color / create a magnified preview around certain pixel coordinates in an image? So it would have all of the same capabilities, but for an image. Additionally, it would be nice if you could change the filepath of the resulting preview image when using ZoomCreate:

Code: Select all

[MeasureCursorColor]
Measure=Plugin
Plugin=CursorColor
Format=RGB
; Image you want to scan
ImageName=C:\Windows\Temp\colorpickerplus-capture.bmp
; X position to get the color for
CursorX=420
; Y position to get the color for
CursorY=69
RealTime=1
ZoomCreate=1
ZoomToWidth=100
ZoomToHeight=100
ZoomFactor=5
ZoomFileName=C:\Windows\Temp\colorpickerplus-zoompreview.bmp
DynamicVariables=1
The reason I ask for this is because for my color picker skin's eyedropper, I set it up so that the magnified preview rides along next to the cursor:
2019-04-11 15_14_42.png
As you can see, since it's just capturing the desktop, that includes the preview window itself. While the preview window is supposed to sit outside the range of CursorColor's preview, moving the mouse too quickly will cause Rainmeter to fall behind, which leads to recursive previews flashing on your screen.

Thanks for your time!

EDIT: I've attached an rmskin of the color picker so you can see why I want these features.

EDIT 2: Oopsie, it appears I forgot to include the HotKey plugin in the rmskin. Oh well!

I don't fully understand your solution, but in any case, I just don't see a big issue with the fact that if you move your mouse really fast, for an instant or two you can get a recursive zoom window. Almost before it can react to that, the preview is moved away with your example skin.

I also don't see any real need to change or set where the preview bitmap is saved. That is just used internally by the plugin, and isn't something the skin should care about.

That's alright, it was mostly just an OCD thing. And the only real reason why I would want to move the file is to keep my repository working tree clean. Thanks anyway!

Personally, I saw no functional benefit at all to having the zoom/preview follow the cursor. I just found it distracting and in the way. I far prefer that it be in a static position in the skin. That is why I did mine the way I did. Now, I grant you that you can get infinite recursion if you hold the eyedropper over that zoom/preview window in my skin, but.. don't... It doesn't hurt anything, as it will only recurse so far and stop, but it's not a useful place to select from.

I'm the opposite. I use Greenshot a lot (like, a LOT) and its preview rides along with the cursor. I much prefer to be able to see the magnification right where I am already looking, rather than having to glance back and forth between the preview and the eyedropper.

To each their own, I guess.
