Guide objects for drawing in user interfaces

A method comprising:

• rendering a user interface to an application comprising a canvas and a guide object positioned on the canvas;
• in response to user input comprising free-form inking on the canvas, determining a position of the user input relative to the guide object on the canvas;
• if the position of the user input is on the guide object, then refraining from drawing a wet ink representation of the free-form inking on the canvas;
• and
• if the position of the user input is within a zone around the guide object, then manipulating the free-form inking such that the wet ink representation of the free-form inking is drawn against an edge of the guide object.

One or more computer readable storage media having program instructions stored thereon that, when executed by a processing system, direct the processing system to at least:

• render a user interface to the application comprising a canvas and a guide object positioned on the canvas;
• in response to user input comprising free-form inking on the canvas, determine a position of the user input relative to the guide object on the canvas;
• if the position of the user input is on the guide object, then refrain from drawing a wet ink representation of the free-form inking on the canvas;
• and
• if the position of the user input is within a zone around the guide object, then manipulate the free-form inking such that the wet ink representation of the free-form inking is drawn against an edge of the guide object.
