I can't create an xImage object from the MemoryStream of a png image I get from Azure blob storage. I always get IvalidFormatException.
The problem are these lines (PdfSharpCore.Utils.ImageSharpImageSource.cs)
using (var stream = imageStream.Invoke()) { var image = Image.Load(stream, out IImageFormat imgFormat);
return new ImageSharpImageSourceImpl(name, image, (int)quality, imgFormat is PngFormat);
}
You should implement somethink like this:
using (var MemoryStream= imageStream.Invoke()) { var image = Image.Load(stream.ToArray(), out IImageFormat imgFormat);
return new ImageSharpImageSourceImpl(name, image, (int)quality, imgFormat is PngFormat);
}
