InkPresenterRuler Class

Definition

Represents a visual stencil, in the form of a straight rule for drawing straight lines, displayed as a semi-transparent overlay on an InkCanvas.

The stencil transforms how an ink stroke is rendered:

  • It snaps the ink stroke to the stencil edge if the pen tip is within a distance threshold (gutter).
  • It acts as a mask and prevents the drawing of an ink stroke within the area obscured by the stencil.

The InkPresenterRuler can be manipulated both programmatically and by the user. It also scales and translates with the InkCanvas.
