Hi I had this error… I’m trying to read an image, resize it and convert it to a byte sequence.
Read file, transform and resize
Transform and Resize
Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AccessViolationException: Attempted to read or write protected memory.

I äm guessing the image hasn’t all been read when the call is made on the data. This is a pretty low-powered PC so the speed throws up this issue more often but I think it happens on the production machine too.
A couple questions :
- Is there a way to confirm that the image has been read entirely?
- What do the read methods of the ImageReader do?
- Could caching an offscreen renderer mean it may fail to finish creating the new SkiaImage before the frame loop is complete?
Thanks and all the best,
