Problem with SkiaSharp on Linux

Aspose.Cells Product Family
1

Hi Aspose team,

We use Aspose.Cells 23.3.0 in our AzureFunction. Everything works fine on Windows.
On Linux, when we call new Workbook(), we get this error:

2024-04-19T09:48:26.226538934Z: [ERROR] Unhandled exception. System.TypeInitializationException: The type initializer for ‘SkiaSharp.SKObject’ threw an exception.

This leads to container restart and as a result unexpected azure function behavior.

We use these libraries:
SkiaSharp 2.88.7
SkiaSharp.NativeAssets.Linux.NoDependencies 2.88.7

Tried different versions, 2.88.8, 2.88.6, 2.88.3, but no success.

Please, advise how to solve this issue.

@sergeykavaliou
Could you try to directly use SkiaSharp to draw an image without Aspose.Cells on AzureFunction linux?

3

removed new Workbook and tried this
using (SKPaint textPaint = new SKPaint { TextSize = 48 })

yes, we have the same issue.

@sergeykavaliou,

The issue may not be with Aspose.Cells. We suggest you to try browsing internet to find relevant threads/documents to figure out your issue.
e.g.
