Image identification.

Hi,
Sorry if this is a duplicate question, I couldn't find the answer anywhere!

I have a byte[] and I want to find if the data is an image or not, if that is an image what's the format? png, bmp, jpg or not identifiable at all!

Currently, I wrote the following code:

using (var image = new MagickImage(fileBytes))
{
    // Converting to PNG
    image.Write(pngMemoryStream, MagickFormat.Png);

    var imageBytes = pngMemoryStream.ToArray();
    // Writing to a png file
}

But the MagickImage throws an exception when the file is not image, it's legitimate to throw but is there a way I can identify before calling the constructor to prevent throwing? (I don't wanna use try/catch)

Also, I saw I have some svg files and the constructor also throws for those svg files! If I could identify first, I could pass MagickFormat.Svg to the constructor!

You can use MagickFormatInfo.Create(fileBytes) for this. It will return null when the format could not be determined.
