Introduction

This is a sample app that demonstrates a custom WPF control. The control allows a user to zoom in and out of a raster image, in this case a fractal, while maintaining accuracy within each pixel of the image. See PanAndZoomViewer.cs

To view the control in action:

• Install and run the app
• Hit the Start button to generate an image
• Zoom in on a single pixel within the image and pan to a point within the pixel you wish to zoom further in on.
• Hit Start to generate a new image centered on the point you selected

The project can also be used as a practical example of a custom WiX installer using a WPF UI. Refer to https://github.com/rsmart8452/Wix4BurnTutorial for a tutorial.

Getting Started

1. Software prerequisites:
   • Heatwave (Wix v4) - found on the Visual Studio Marketplace
   • IsWix (External app) - download and install from GitHub https://github.com/iswix-llc/iswix/releases
2. Software dependencies:
   • .NET 8, specifically TargetFramework=net8.0-windows
   • WPF (which requires targetting Windows)

Build

1. Open SLN file in Visual Studio
2. Build the solution

Integration Test

1. Open a command terminal of your choice.
   • In the Visual Studio menus, View\Terminal
   • Either Powershell or Command Prompt will work.
2. Using the Terminal, run .\sandbox.wsb
   • This starts a Windows sandbox.
3. Wait for it to open a couple of File Explorer windows.
   • One of these will show C:\Fractal_Source
     • You can test the installer from C:\Fractal_Source\FractalFlair_Setup\bin\x64\Release.
   • The other will show where FractalFlair will be installed.
     • Use this to verify the installer runs correctly.
4. Verify that the installer created a Start Menu item for FractalFlair.
5. Test the app by using this shortcut to run it.
