dotnetcore-image

Solution of .NET Core GDI+(Image) on Linux/Docker.

.NET Core does not provide an Image, Bitmap, etc. class by default.Microsoft officially provides a component that provides access to GDI+ graphics functionality - System.Drawing.Common.This seems to be no abnormal.I believe most people use the Windows to develop applications.If we use System.Drawing.Common, we have no problems developing, debugging, and running on Windows.But if we deploy the program to run on Linux, this will get a GDI+ exception, because we can no longer use GDI+ on Linux. libgdiplus(https://github.com/mono/libgdiplus) is C-based implementation of the GDI+ API .We can use it to solve our problem.

Quick installation libgdiplus

1.In the Linux system

CentOS 7

sudo curl https://raw.githubusercontent.com/stulzq/awesome-dotnetcore-image/master/install/centos7.sh|sh

Ubuntu

sudo curl https://raw.githubusercontent.com/stulzq/awesome-dotnetcore-image/master/install/ubuntu.sh|sh

2.In Docker(Base on Linux Image)

This project builds an ASP.NET Core image to replace the official image(microsoft/dotnet).These images base on official image and install libgdiplus.

ASP.NET Core 2.2

base on microsoft/dotnet:2.2.0-aspnetcore-runtime

FROM stulzq/dotnet:2.2.0-aspnetcore-runtime-with-image
