  2. What we will cover today • Why incorporate scanning in your app? • Your app + scanner device compatibility • Simplicity of the new Scanner namespace • Demo: scanning from an app • Scan API code snippets

  3. archive  share 📎 modify ✎ Digital world extract  • Users want experiences, information, intelligence

  4. Digital world • Things in the physical world are being left behind  checks 📃legal contracts  store receipts  photos  medical records

  5. There are more scanners out there than you may think 66%of printers connected to Windows are also scanners

  6. Why is content left behind? JPEG, OXPS , Windows 8.1

  7. Scan Runtime APIs built on top of WIA means that you can use any Windows logoed scanner Scan Runtime APIs Windows 8.1 Store app Windows 8.1 Store app Windows Imaging Acquisition (WIA) platform • New Scan Runtime APIs are compatible with certified WIA 2.0 drivers WIA API (COM) These APIs can be used to scan from Windows Store and from Desktop apps Windows Store apps Desktop apps Hardware scanner devices (Stand-alone or MFP)

  8. Windowshas you covered • Windows 8.1 supports the vast majority of scanners • available in the ecosystem today  • More than 500 USB scanners are supported inbox with many more on Windows Update • All WS-Scan network scanners are supported by a class driver    🔐🔒💾 • WIA 2.0/WS-Scan support is required for Windows logoed scanners (since 2006) • Windows 8.1 supports more than 500 scanners inbox • Windows Update only provides WIA 2.0 drivers

  9. Optional: Set scan settings 1 Enumerate scanners 2 Get scanner object How to enable scanning 3 Scan Optional: Preview

  15. Demos • Enumerate all connected scanners • Scan from auto-configured, flatbed, feeder scan sources • Override scan settings (scan area, resolution, format…) • Handle scan progress

  16. 1 Enumerate scanners 1 CreateWatcher(DeviceClass.ImageScanner) to enumerate using a DeviceWatcher (Windows.Devices.Enumeration) 2 Get scanner object 2 FromIdAsync(deviceId) for scanner ImageScannerobject Optional: Set scan settings How we enabled scanning Format, Resolution, Duplex… to set scan settings (per scan source) Optional: Preview ScanPreviewToStreamAsync() to scan file to stream 3 Scan 3 ScanFilesToFolderAsync() to scan file to folder
