Unexpected change in Image dimensions when loading from Stream in .NET MAUI on Android

[VishalOmprasad]

In a .NET MAUI project, I observed a change in image dimensions when loading an image using a stream:
image.Source = ImageSource.FromStream(_ => FileSystem.OpenAppPackageFileAsync($"images/{_filename}"));

This behavior is specifically noticeable on the Android platform. When measuring the image using Image.ComputeDesiredSize(), the returned size is significantly smaller than expected.

However, when loading the same image using:
image.Source = ImageSource.FromFile(_filename);

The computed size matches the image’s actual dimensions.

Questions:

• Is this a known framework limitation in .NET MAUI that causes the image dimensions to shrink when loaded from a stream?
• Are there any recommended workarounds or best practices to ensure consistent sizing across platforms when using ImageSource.FromStream?

Any insights, workarounds, or roadmap updates would be greatly appreciated. Thanks in advance!

CoPilot AI found this bug, but it is not related. The second one, looks more related, as it is Android specific too.
