How can I know what image format I get from a stream?

Question

I get a byte stream from some web service. This byte stream contains the binary date of an image and I\'m using the method below to convert it to an Image instance.

Answer 1

You may checkout the Image.RawFormat property. So once you load the image from the stream you could test:

if (ImageFormat.Jpeg.Equals(image.RawFormat))
{
    // JPEG
}
else if (ImageFormat.Png.Equals(image.RawFormat))
{
    // PNG
}
else if (ImageFormat.Gif.Equals(image.RawFormat))
{
    // GIF
}
... etc
