JavaFX: get the format (PNG, JPG ..) of an image?

I am creating an application that only accepts PNG images for some reason.

How can I check if an image is really a PNG image? I am currently using the JavaFX 2 Image class to load an image.

Thanks for any hint!

I do this in my own application, validating the Mime Type file before processing it. There are several SO threads out there suggesting how to get Mime types in Java.

If you don't trust the filename, a simple check is to read the first 8 bytes (s FileInputStream

) and check if they match the PNG signature (related: fooobar.com/questions/1224133 / ... )
