How to get resizing info from SymbolInstance?

ZenoZ

Hi, I want get resizing info from SymbolInstance. But I couldn't see any props on SymbolInstance or Layer.

You can compare the instance’s sizing to the source’s sizing.

let doc = sketch.getSelectedDocument()
let selection = doc.selectedLayers.layers[0]

let instanceWidth = selection.frame.width
let instanceHeight = selection.frame.height

let source = selection.master
let sourceWidth = source.frame.width
let sourceHeight = source.frame.height

let scaleWidth = instanceWidth / sourceWidth
let scaleHeight = instanceHeight / sourceHeight

console.log(scaleWidth,scaleHeight)

If the scaleWidth and scaleHeight are the same then you know it has been evenly scaled down or up.

Hi, thank you.

And how to get the overrides rendered size in resized SymbolInstance.

I found the size in frame property, but it is initial size.

Due to there has not resizing info, I don't know how to calculate rendered size when SymbolInstance resized.

Initial thought is to duplicate the SymbolInstance, detach it, and then read the properties (and remove the copy). There might be a way to do it without detaching via the JS API but I’m doubtful.

Would official add more info in JS API?
