Hi, locally on my windows DEV machine everything works fine but I run my tests on Docker it fails with:

Relevant fragment of the Dockerfile:

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
[...]
RUN apt-get update && apt-get install -y libgdiplus
RUN sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
RUN apt-get update; apt-get install -y ttf-mscorefonts-installer fontconfig

I have tried changing the library to Aspose.PDF, of course it did not help.

Any ideas how to proceed?

@fchilvarguer

Could you please share your sample code snippet and complete docker file for our reference? We need to investigate this issue in details. We will log an investigation ticket and share the ID with you.

Unfortunately I cannot share the original code it is prioprietary, same with the full Dockerfile.
I will try to prepare small program outside of the commercial project to highlight the problem.

However, I think that possibly I gave you enough information to be able to reproduce the problem on your own. Other Dockerfile instructions are not relevant to the problem at hand and the documents we create are relatively simple so I also can’t see how they could be the source of the problem.

In the meantime I had to go back to 22.12.0 to make it work temporarily.
For this version it works fine, but I still would like to use the latest version of course.

Do you have any even potential solutions I could try on my own? Maybe other linux packages that I am missing or something?

Like expected it was quite straitghforward to reproduce in minimal example.
You need to
a) download the code
b) Add Aspose.PDF.lic.xml file, obviously I didn’t add mine since this is public forum
c) docker-compose up --build api
d) In browser http://localhost:4208/swagger/index.html and execute file/pdf endpoint
e) System.Drawing.Common is not supported on this platform. appearsproblem_reproduction.zip (7.4 KB)

The issue can be reproduced on Aspose.PDF.Drawing 23.8, but can not on 23.9, you should please update to the latest version.
