Simple inking sample

Shows how to use ink functionality (such as capturing ink from user input and performing handwriting recognition on ink strokes) in Universal Windows apps.

Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Specifically, this sample covers using the Windows.UI.Input.Inking APIs to do the following:

  • Capture user input and render as ink strokes
  • Create an ink toolbar which is associated with an ink canvas
  • Add custom buttons to the ink toolbar
  • Create an ink toolbar with only specified buttons
  • Control multiple ink canvases with a single ink toolbar
  • Save and load ink strokes
  • Erase ink strokes
  • Create and select different types of pens
  • Change which input types (Mouse/Touch/Pen) are used for inking
  • Recognize handwriting from ink strokes
  • Select ink strokes
  • Create a ruler and protractor, show them, hide them, customize them, and reposition them
  • Manipulate wet ink strokes
    • make strokes follow a shape
    • complete a stroke prematurely if conditions are met
  • Use ink stroke timestamps to replay ink strokes
  • Use a png as the background of an InkToolbarCustomPenButton and bind its color to the SelectedBrush property of the buttons
  • Change the rendering of the strokes and the color palette change by changing the high contrast adjustment mode
  • Enable pencil tilt
