Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0 - for Xbox, see UWP features that aren't yet supported on Xbox)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Examples

The following example demonstrates how to set a default drawing attribute for all strokes managed by an InkManager object (inkManager).

// Create the InkManager instance.
Windows.UI.Input.Inking.InkManager inkManager = 
  new Windows.UI.Input.Inking.InkManager();
Windows.UI.Input.Inking.InkDrawingAttributes drawingAttributes = 
  new Windows.UI.Input.Inking.InkDrawingAttributes();
// True is the Default value for fitToCurve.
drawingAttributes.FitToCurve = false;
// Set color to red (default is black).
drawingAttributes.Color = Windows.UI.Colors.CornflowerBlue;
inkManager.SetDefaultDrawingAttributes(drawingAttributes);

The following example demonstrates how to set a drawing attribute for a specific stroke.

Note

You cannot set the DrawingAttributes property of the stroke directly. You must create a copy of the InkDrawingAttributes of the stroke, set the desired values for that InkDrawingAttributes object, and then assign the new InkDrawingAttributes to the DrawingAttributes of the stroke, as shown here.

// Get the InkStroke objects.
IReadOnlyList<InkStroke> inkStrokes = inkManager.GetStrokes();
Windows.UI.Input.Inking.InkStroke cloneStroke = 
  inkStrokes.GetAt(index).Clone();
Windows.UI.Input.Inking.InkDrawingAttributes drawingAttributes = 
  cloneStroke.DrawingAttributes;
drawingAttributes.PenTip = Windows.UI.Input.Inking.PenTipShape.Rectangle;
cloneStroke.DrawingAttributes = drawingAttributes;

Remarks

InkDrawingAttributes can be set globally through the SetDefaultDrawingAttributes method of an InkManager object or an InkStrokeBuilder object. They can also be set on an individual InkStroke object through the DrawingAttributes property.

Constructors

InkDrawingAttributes()

Creates a new InkDrawingAttributes object that is used to specify InkStroke attributes.

Properties

Color	Gets or sets a value that indicates the color of an InkStroke.
DrawAsHighlighter	Gets or sets a value that indicates whether the InkStroke is rendered as a highlighter overlay. The stroke is typically set to a bright color, such as yellow.
FitToCurve	Gets or sets a value that indicates whether a Bezier curve or a collection of straight line segments is used to draw an InkStroke.
IgnorePressure	Gets or sets a value that indicates whether the pressure of the contact on the digitizer surface is ignored when you draw an InkStroke.
IgnoreTilt	Gets or sets a value that indicates whether the tilt (tiltx, tilty) of the contact on the digitizer surface is ignored when you draw an InkStroke.
Kind	Gets the InkDrawingAttributes that describe the characteristics of a specific type of InkStroke.
ModelerAttributes	Gets an instance of a ModelerAttributes object for accessing modeler properties of an ink stroke.
PencilProperties	Gets an instance of an InkDrawingAttributesPencilProperties object for setting properties characteristic to a pencil stroke.
PenTip	Gets or sets a value that indicates the shape of the pen tip when you draw an InkStroke.
PenTipTransform	Gets or sets an affine transformation matrix applied to the PenTipShape used for an InkStroke.
Size	Gets or sets a value that indicates the dimensions of the pen tip (PenTip) used to draw an InkStroke.

Methods

CreateForPencil()

Creates an InkDrawingAttributes object for rendering an ink stroke with pencil characteristics.
