Hi! We have problems in converting Slides to PNG in Linux with libgdiplus.
Can i use Aspose.Drawing.dll instead System.Drawing.Common.dll in Aspose.Slides for .NET to avoid errors from “libgdiplus”?
If yes, how can i do it?
Now when i add Aspose.Drawing from NuGet to current project, i have many errors CS0433 like this:
|Error|CS0433|The type ‘ImageFormat’ exists in both ‘Aspose.Drawing, Version=21.5.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56’ and ‘System.Drawing.Common, Version=4.0.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ Preview.Conversion.StandartPlugin
@demonspe,
Welcome to our community! Thank you for the issue description. I added a ticket with ID SLIDESNET-42656 in our tracking system. Our development team will investigate this case. I answer your questions as soon as possible.
@demonspe,
Our development team investigated the issue. It is not possible to use Aspose.Drawing library for Slides instead of System.Drawing.Common on Linux. System.Drawing.Common is .NET Standard library that defines abstraction of the graphic system. The actual implementation used by System.Drawing.Common depends on the platform it runs on. For Windows, it will be GDI, for Linux - libgdiplus. Aspose.Slides refers to System.Drawing.Common and this reference cannot be easily replaced with something else.
To investigate this case and help you, please share and specify the following:
@0x0dh,
I was unable to reproduce the text issues shown in your screenshots, but similar issues appeared. I added a ticket with ID SLIDESNET-42734 in our tracking system. Our development team will investigate this case. You will be notified when these issues are fixed. It would be great if you could check the problems with the latest version of Aspose.Slides and share the results.
@0x0dh,
Unfortunately, there will not be any changes in version 21.5. I requested an estimated time to fix this issue from our development team. I will let you know soon.
@0x0dh,
Our development team is still working on the issue. I requested the estimated time to fix this problem again. I will let you know as soon as possible.
@0x0dh,
Our development team investigated the issue. The problem is that the Windows font package included in the container (ttf-mscorefonts-installer) does not include the Segoe UI font. For the presentation to be displayed using the Segoe UI font, the font must be included in the container separately.
I attached a container creation file in which this font is explicitly installed (Dockerfile.zip). To create the container correctly, the Segoe UI font group must be placed in the publish/fonts folder. In the future, you can yourself choose how and where to place and use fonts to include them in the container.
Please let us know if this recommendation solves your problem. If the issue persists, we will continue to investigate it.
Hi, I am facing the same problem. I am using Aspose.Slides for .NET
My actual error on the Ubuntu 18.04.6 LTS server is

I found the answer to this error in this link
After following the above link, When I started using Aspose.Drawing for .NET with Aspose.Slides for .NET, I get the error
CS0433|The type ‘Bitmap’ exists in both ‘Aspose.Drawing, Version=21.9.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56’ and 'System.Drawing.Common, Version=5.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51
I am trying to generate thumbnails using the following line
// Create a full scale image
Bitmap bmp = sld.GetThumbnail(1f, 1f);
