Simple imaging sample

Shows some common imaging scenarios for Universal Windows apps including metadata and editing/saving.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a 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 demonstrates how to:

• Read, process and edit common image metadata and properties including:
  • EXIF orientation
  • Author, title, and keywords
  • Geotags
• Perform scaling and rotation while respecting EXIF orientation
• Optimize image saving

Sample contents

C# version

• Scenario1.xaml, Scenario1.xaml.cs: Use the property system APIs (Windows.Storage.FileProperties) to read and edit bitmap properties from an image.
• Scenario2.xaml, Scenario2.xaml.cs: Use the imaging APIs (Windows.Graphics.Imaging) to read and edit bitmap properties and apply transformations such as scale, crop and rotate.
• Helpers.cs: Helper functionality including handling/converting EXIF orientation values.

All other files provide common SDK sample functionality.
