[BUG] The type initializer for 'SkiaSharp.SKData' threw an exception (even after applying the solution of issue #2124).

[ak4shp]

Description

I'm trying to resize images (actually making thumbnail of 200x150) using SkiaSharp. The code works fine in my local setup which has Visual Studio Code 1.77.3, .NET 7.0.400 and Windows 10 OS. But when I deply the build of the code to Google Cloud Plateform (GCP) with docker, the above mentioned exception occurs.

I tried the GCP deployment with following packages: Note: The deployed code was written in Microsoft Visual Studio Community 2022 (64 bit), .NET 6, Windows 10.

SkiaSharp (2.88.5) SkiaSharp.Views.Blazor (2.88.5) (Solution for issue #2124) SkiaSharp.NativeAssets.Linux (2.88.5) SkiaSharp.NativeAssets.Linux.NoDependencies (2.88.5) SkiaSharp.NativeAssets.WebAsssembly (2.88.5)

On my local, the SkiaSharp (2.88.5) alone worked.

Code

public IFormFile getThumbnailFromBase64(string base64String)
{
    byte[] imageBytes = Convert.FromBase64String(base64String);

    SKImage image = SKImage.FromEncodedData(imageBytes);
    SKBitmap imageBitmap = SKBitmap.FromImage(image);

    SKImageInfo info = new SKImageInfo(200, 150);
    SKFilterQuality quality = SKFilterQuality.High;

    SKBitmap thumbnail = imageBitmap.Resize(imageInfo, quality);
    SKData thumbData = thumbnail.Encode(SKEncodedImageFormat.Jpeg, 100);

    byte[] thumbByte = thumbData.ToArray();
    var stream = new MemoryStream(thumbByte);
    IformFile thumbFile = new FormFile(stream, 0, thumbByte.Length, "ImageFile", "ImageFile");

    return thumbFile;
}

Expected Behavior

The code should take base64 image string and return an object of IFormFile after deploying to GCP.

Also the exception should give more description or reason of the error and possible suggestions.

What this "type initializer" means in the exception?

Actual Behavior

I put logger after each line of the above code. The only logger output I got is after byte[] imageBytes = Convert.FromBase64String(base64String); line. I my thinking the exception The type initializer for 'SkiaSharp.SKData' threw an exception occured at the line where I used SKImage class.

The "type initializer" is just the runtime component that constructs objects. So, the error is saying there was an exception in the constructor.

So, this exception is saying it was unable to load the libSkiaSharp native binary.

Are you specifically using Blazor? Or, just web assembly?

Or, is this a native Linux app running in docker and the exception is happening on the server?

Hi @mattleibow, Thanks for the quick look up on the issue.

I am not using Blazor or Web assembly specifically. The same code with only SkiaSharp (2.88.5) is working as expected on my Windows 10 console app with .NET 6. As per the suggestions across the web, I added all above mentioned SkiaSharp packages hoping atleast any of them might be the right one.

Yes, it is deployed to GCP (Google cloud platforms) Container Registry and build with docker. The exception is happening only on the server i.e GCP.

Am I referencing to a wrong packege ? Or some plateform compatibility issues?

I have the same problem... the only difference is that i'am running my api in AWS ECS (Docker). i've installed the same SkiaSharp.NativeAssets.Linux and my docker file contain this: RUN apt-get install -y libfontconfig1 RUN apt-get update && apt-get install -y apt-utils libgdiplus libc6-dev

I don't know what to do else.

You should add reference to SkiaSharp.NativeAssets.Linux.NoDependencies: SkiaSharp.NativeAssets.Linux.NoDependencies.

[narojay]

You should add reference to SkiaSharp.NativeAssets.Linux.NoDependencies: SkiaSharp.NativeAssets.Linux.NoDependencies.

not work

You should add reference to SkiaSharp.NativeAssets.Linux.NoDependencies: SkiaSharp.NativeAssets.Linux.NoDependencies.

This worked for me after adding missing 2 libs (in case)

    libfontconfig1 \
    libfreetype6 \
    && rm -rf /var/lib/apt/lists/*``` 
    into the DockerFile.
