We currently have an issue where the thumbnail uses Arial Regular instead of Arial Bold like the title has in the presentation. We do have occurences of mixed bold and non bold in one text field.

Thanks for your reply. I have the most recent version of Aspose.Slides(22.12). Here’s the attachment with the presentation and thumbnail: Bold test.zip (31.1 KB)

The C# code that reproduces the problem is:

Bitmap slideThumbnail;
slideThumbnail = titleSlidePresentation.Slides[0].GetThumbnail(new Size(Width, Height));

using var thumbnailStream = new MemoryStream();
slideThumbnail.Save(thumbnailStream, ImageFormat.Jpeg);
var jpgData = thumbnailStream.ToArray();
slideThumbnail.Dispose();

Where the width is 640 and the height 360.

The OS is a docker image with windows subsystem for linux: 5.10.102.1-microsoft-standard-WSL2

We are targeting .NET 6.0, the exact runtime at the moment is: *Microsoft.AspNetCore.App 6.0.13 *
Microsoft.NETCore.App 6.0.13

Kind regards,

Yorick
