Hi How are you? I hope you are doing well.
I'm trying to use this library in Linux server without X-Server. When I tried to use the method AutoSizeColumns I got this error:
System.NotSupportedException: Could not open display (X-Server required. Check your DISPLAY environment variable)
at System.Drawing.Graphics.FromHwnd(IntPtr hwnd)
at NPOI.SS.Util.SheetUtil.getDefaultCharWidth(IWorkbook wb)
at NPOI.SS.Util.SheetUtil.GetColumnWidth(ISheet sheet, Int32 column, Boolean useMergedCells)

Any suggestions?
Thanks!

Environment:
.net core 3.0
docker container (alpine)

Docker File entry:
FROM mcr.microsoft.com/dotnet/core/aspnet:3.0-alpine as services
RUN echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories
RUN apk --update add libgdiplus libx11-dev fontconfig ttf-dejavu --update-cache

Please note that this was working fine in .net core 2.2:
FROM microsoft/dotnet:2.2-aspnetcore-runtime-alpine as services
RUN apk add libgdiplus-dev fontconfig ttf-dejavu libc-dev --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
