Unable to use GdPicture in an Azure Function

[proit]

Hi there

We want to use GdPicture in an Azure Function to manipulate pdf documents (removing blank pages, extract barcodes etc.). We added the latest GdPicture.Api nuget package. The Azure Function itself runs as .net 8 isolated process in the consumption plan on linux. Whenever we try to initiate GdPicture we get the following error:

Code: Select all

System.Exception: GdPicture runtime exception: Can not find GdPicture.NET.14.filters.64.so. Please, copy last version of this dll into your application directory at: /home/site/wwwroot

The required files are not located in the root directory but in the sub folder runtimes\linux-x64\native.

When I debug the function locally everything works as expected.

What do we have to change so that GdPicture can be used in an Azure Function running on the linux stack in .net 8?

Thank you for your help.
