Windows-only ImageSharp interop sample showing how to edit a System.Drawing.Bitmap through Image.WrapMemory(...).

Run the project from the repository root:

dotnet run --project SixLabors.Samples.ImageSharp.SystemDrawingInterop\SixLabors.Samples.ImageSharp.SystemDrawingInterop.csproj -c Release

Shows how to wrap externally-owned bitmap memory:

• loads a JPEG into a System.Drawing.Bitmap
• locks the bitmap with LockBits(...)
• wraps the locked Format24bppRgb memory as Image<Bgr24> with Image.WrapMemory(...)
• applies normal ImageSharp processors to the wrapped memory
• unlocks and saves the original System.Drawing.Bitmap

Format24bppRgb stores pixels in BGR byte order, so the sample wraps the locked bitmap as Bgr24 and processes the bitmap in place without copying pixels into a separate ImageSharp-owned buffer.

Wrapped images should only be used with in-place operations. Do not resize a wrapped image: ImageSharp does not own the external buffer and cannot reallocate the System.Drawing.Bitmap storage to match a different width, height, or stride.
