ASP.NET 7 Docker image: mcr.microsoft.com/dotnet/aspnet:7.0 Windows: ok it works Linux (Debian): not I can't test with other images, e.g. ubuntu

My code:

            BarcodeStandard.Barcode barcode = new BarcodeStandard.Barcode();
            barcode.IncludeLabel = false;
            barcode.EncodedType = BarcodeStandard.Type.Code128;
            barcode.Encode(BarcodeStandard.Type.Code128, data);
            barcode.SaveImage(path, BarcodeStandard.SaveTypes.Png);

I believe I will have to create an intermediate image by adding something like: sudo apt-get install -y libfontconfig1

or try to use the package SkiaSharp.NativeAssets.Linux.NoDependencies

as per: https://github.com/mono/SkiaSharp/issues/1341

updated

when trying to mount a custom image:

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS final-stage
RUN apt-get update && apt-get install -y --no-install-recommends fontconfig libfontconfig1
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get install -y tzdata

It didn't help, same error.

It worked! putting SkiaSharp.NativeAssets.Linux.NoDependencies in the project stopped the problem.

I'm going to make a PR
