SuggestedImageFileExtension-Altova
suggested-image-file-extension(Base64String as string) as string? XP3.1 XQ3.1 Takes the Base64 encoding of an image file as its argument and returns the file extension of the image as recorded in the Base64-encoding of the image. The returned value is a suggestion based on the image type information available in the encoding. If this information is not available, then an empty string is returned. This function is useful if you wish to save a Base64 image as a file and wish to dynamically retrieve an appropriate file extension.
In the examples above, the nodes supplied as the argument of the function are assumed to contain a Base64-encoded image. The first example retrieves jpg as the file's type and extension. In the second example, the submitted Base64 encoding does not provide usable file extension information.
