Image Attachment to a Text Object

imageAttachment.js

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

let imgPath = "/Users/Kski/Downloads/image-2.png"
let fileWrapper = NSFileWrapper.alloc().initWithPath(imgPath)
let attachment = NSTextAttachment.alloc().initWithFileWrapper(fileWrapper)
attachment.bounds = NSMakeRect(0,0,100,30) //seems like these bounds don't do anything?

// Currently could only figure out how to add it in when editing
let textStorage = selection.sketchObject.editingDelegate().textView().textStorage()
let attachmentAttr = NSAttributedString.attributedStringWithAttachment(attachment)

textStorage.replaceCharactersInRange_withAttributedString(NSMakeRange(4,0),attachmentAttr)
