In 5.207 alpha I have added a very basic version of this "Measure Area On Screen". It saves the result into these variables:
BTTActionMeasuredX, BTTActionMeasuredY, BTTActionMeasuredWidth, BTTActionMeasuredHeight
For writing them to the clipboard you'd currently need to run a little script "Run Real java Script"
//if you rename this, make sure to also rename it in the "function to call" field below.
async function copyDimensions() {
let x = await get_number_variable("BTTActionMeasuredX");
let y = await get_number_variable("BTTActionMeasuredY");
let width = await get_number_variable("BTTActionMeasuredWidth");
let height = await get_number_variable("BTTActionMeasuredHeight");
// format in any way you want
let clipboardString = `x: ${x}px, y: ${y}px, width: ${width}px, height: ${height}px`;
await set_clipboard_content({content: clipboardString, format: 'NSPasteboardTypeString'})
return clipboardString;
}
//edit: accidental minimum window size has been removed in 5.208 alpha
