I did check .data but I cannot access points

to give you Idea what I want to do is I need to reach points so I can match between what it was drew and what user drawing

@X901 There's a property called elements on the class CanvasData, whitch is the type of data property on Canvas. All elements are follow the CanvasElement protocol. Includes lines(LineStrip) you draw on the canvas. A LineStrip is constructed by several MLLines, a MLLine is a strait line contains two points for begin and end, and other properties such as color, size etc.

@X901 There are two builtin tools called DataExporter and DataImporter. You can export all points and other elements data into a JSON file with DataExporter and then import them to another canvas on even other devices later by DataImporter.

Thank you ,but it looks like I will need sometimes to understand the data.
