Why do I retract a step and still get a stroke that includes the retracted step
Thank you for contacting us.
In oder to answer your question, could you please detail what you mean by retract a step? Do you mean erase a stroke? Perform an undo operation?
Do you have a video or snapshot showing your issue?
Which API are you using?
Thank you for your update.
I am not sure to get your point.
For un undo implementation based on iinkJS you can refer to the following example:
