WPF: CroppedBitmap crashes with AccessViolationException

See original GitHub issue

This issue has been moved from a ticket on Developer Community.

[severity:I’m unable to use this version] I’m trying to save a screenshot of a diagram I generated in my .NET 5 software.

The diagram in the WPF window consists of thousands of WPF elements and has a width of approx. 300,000*2500 pixels.

I’m using RenderTargetBitmap to create a bitmap from my WPF window content.

When doing so, …

PngBitmapEncoder throws an ArgumentException, claiming it cannot convert such large image.
Splitting the image using CroppedBitmap in slices of 20,000*2500 pixels each results in an AccessViolationException.

Please refer to the step recorder information for further details.
