Converting PDF and Microsoft Office Files to Images in C# on Linux

[orenco]

Hi

We need to convert PDF and Microsoft Office files (DOC/X, XLS/X, PPT/X) to images.
We have a .Net 7 service, and we need to run it as a Linux docker on Kubernetes.

What should be the base image if we need to support ALL the above file types?
Is it mcr.microsoft.com/dotnet/sdk:7.0 ?
or mcr.microsoft.com/dotnet/sdk:6.0 ?
or any other image.

I understood that Aspose.Slides is supported only in Windows, unless we use a cross-platform ZIP package for .Net 6:

Convert PPT to Image in .NET 7 on Linux: System.Drawing.Common Is Not Supported

Hi Sergei, The change you suggested helped. However, we still have the same error when trying to convert a PPT file to PNG image using Slides, And Slides doesn’t have Aspose.Slides.Drawing. So what should we do? This is the code we use: var pngImages = new List<byte[]>(); for (var p = 0; p < 3; p++) { var slide = ppDoc.Slides[p]; var extractedPage = slide.GetThumbnail(1f, 1f); var ms = new MemoryStream(); extractedPage.Save(ms, System.Drawing.Imaging.ImageFormat.Png); p…

Regarding the above solution we use, is this the best practice if we need to use Aspose with Linux (as a service)?

@orenco,

Regarding Aspose.Cells, we do provide separate Aspose.Cells for .NET7 Dll to be used for non-Windows platforms. Please get/use the Aspose.Cells.Dll from “net7.0” folder at your installation directory.
