ERROR:The type initializer for 'Gdip' threw an exception on Ubunto server

[softsan]

Tried using System.Drawing.Common package for my .net core web api project. It runs fine under windows but on ubunto (which is my host server), it throws following errors:
This is the method i used to generate thumbnail:

public static bool CreateThumbnail(int Width, int Height, Stream filePath, string saveFilePath)
        {

            try
            {
                var byteArray = filePath;  
                var streamImg = Image.FromStream(byteArray);

                Bitmap sourceImage = new Bitmap(streamImg);
                using (Bitmap objBitmap = new Bitmap(Width, Height))
                {
                    objBitmap.SetResolution(sourceImage.HorizontalResolution, sourceImage.VerticalResolution);
                    using (Graphics objGraphics = Graphics.FromImage(objBitmap))
                    {
                        // Set the graphic format for better result cropping   
                        objGraphics.SmoothingMode = SmoothingMode.HighQuality;
                        objGraphics.PixelOffsetMode = PixelOffsetMode.HighSpeed;
                        objGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
                        objGraphics.CompositingQuality = CompositingQuality.HighQuality;
                        objGraphics.DrawImage(sourceImage, 0, 0, Width, Height);

                        // Save the file path, note we use png format to support png file   
                        objBitmap.Save(saveFilePath);
                    }
                }
            }
            catch (Exception ex)
            {
                LogHelper.Log("Create Thumbnail: ERROR:" + ex.Message + "\n" + ex.StackTrace);
                return false;
            }
            return true;
        }

Already installed
sudo apt-get install libgdiplus
and did this too:

cd /usr/lib
sudo ln -s libgdiplus.so gdiplus.dll

So Any workaround or thoughts on this?

[safern]

cd /usr/lib
sudo ln -s libgdiplus.so gdiplus.dll

Did you try without doing this step? This shouldn't be necessary as we do search for libgdiplus.so in Unix.

We only try to load gdiplus.dll when running in Windows.

[softsan]

First tried without

cd /usr/lib
sudo ln -s libgdiplus.so gdiplus.dll

but it didn;t work so used above solution but none of them work either.

[safern]

Could you try adding this path to LD_LIBRARY_PATH?

export LD_LIBRARY_PATH=/usr/lib

And also could you confirm that libgdiplus.so is present under /usr/lib?

If that doesn't work, would you mind running a little c app just to see if you can load libgdiplus there?

#include <dlfcn.h>
#include <stdio.h>
int main(void)
{
  void* ptr = dlopen("libgdiplus.so", 0x002);
  printf("Found: %s\n", ptr != 0 ? "yes" : "no");
  return 0;
}

[safern]

@softsan any luck?

[softsan]

Sorry for late reply.
System.Drawing.Common didn't work for me so i gave it up(since it was urgent and didn't get time to experiments).
so I used CoreCompact.System.Drawing library which resolved my issue.
Thanks.

Ok, I just wanted to understand what was happening to fix it if it was a real product issue. I'm pretty sure that setting the LD_LIBRARY_PATH env variable correctly should fix your issue. Whenever you have time would you mind checking and if it still fails, I would love to dive into the issue and fix it.

Will close the issue in the meantime, please feel free to re-open and I'm sorry you where hitting this.

Hey
I also experience the same issue
I tried all of the above solutions, even with the export LD_LIBRARY_PATH=/usr/lib

Noob question: do I need to restart server or something else? (I just restarted the service by running dotnet run)

I tried to run your code
#include <dlfcn.h>
#include <stdio.h>
int main(void)
{
void* ptr = dlopen("libgdiplus.so", 0x002);
printf("Found: %s\n", ptr != 0 ? "yes" : "no");
return 0;
}

And here is the result

[safern]

Did you try installing libgdiplus?

And also could you confirm that libgdiplus.so is present under /usr/lib?

What OS is your server running?

Hi,

I've got the same problem.

1. Installed libgdiplus
2. I can find it under /usr/lib
3. sudo ln -s libgdiplus.so gdiplus.dll
4. export LD_LIBRARY_PATH=/usr/lib
5. Restart service and still

The type initializer for 'Gdip' threw an exception.

I'll try to use CoreCompact.System.Drawing as softsan wrote

Installed libc6-dev and everything works

Hello guys, someone please help me to fix this error,

I've always got "The type initializer for 'Gdip' threw an exception." when i deploy my .NetCore API in ubuntu server. But the codes is working in my local machine (Windows).

I'm trying to get a image icon in my server folder named pictures/3FALogo.ico

I've always got this error response in my ubuntu server when accessing the API endpoint.

Someone can help me?
Thank you.

[LHeczko]

Have you installed libc6-dev on linux? For me it was the problem.

Got same issue:
I am using CentOS 7 and .NET Core 2.2, using System.Drawing.Common package, got same error: "error: The type initializer for 'Gdip' threw an exception.".
And I tried to use sudo yum install libgdiplus, it looks good but I cannot find neither libgdiplus.so, nor gdiplus.dll in the folder.

BTW, it's working fine on my local Windows 10 when debugging, but does not working on CentOS.
Could someone help me out? Thank you.

[sw0]

Fixed
I use # find -name libgdiplus* and find the files exists in /usr/lib64 instead of /usr/lib, so I follow the instructions after replacing the correct folder /usr/lib64. It works!
Thank for the instructions here.
