Screen ruler utility
Screen ruler allows you to quickly measure pixels on your screen based on image edge detection. This was inspired by Pete Blois's Rooler.
How to activate
Just press ⊞ Win+Shift+M to activate and then select which tool you want to measure with. To exit, just hit Esc or click the toolbar.
How to use
- Bounds (Dashed square symbol): This is a bounding box. Click and drag with your mouse. If you hold Shift, the box will stay until you cancel the interaction
- Spacing (+ symbol): This will measure horizontal and vertical spacing at the same time. Click the symbol and move your mouse to your target location.
- Horizontal (- symbol): This will measure only horizontal spacing. Click the symbol and move your mouse to your target location.
- Vertical (| symbol):This will measure only vertical spacing. Click the symbol and move your mouse to your target location.
- Cancel interaction: Esc or mouse click
From the Settings menu, the following options can be configured:
|Activation shortcut||The customizable keyboard command to turn on or off the toolbar.|
|Capture screen continuously during measuring||When off, the utility takes a single snapshot of your screen. When this is turned on, the utility will attempt real-time detection. This mode will consume more resources when in use.|
|Per color channel edge detection||Test all color channels are within a tolerance distance from each other. Otherwise, check that the sum of all color channels differences is smaller than the tolerance.|
|Pixel tolerance for edge detection||A value between 0-255. A higher value will provide a higher variation so it will be more forgiving with things like gradients and shadows.|
|Draw feet on the cross||Adds small feet for additional visual capture.|
|Line color||The color for the line that does the measuring.|
