Of course not.  It simply means you need to look at other image
attributes to see how to interpret the data.  What in specific you'll
need to check will vary from one image format to another.  I recommend
reading the PDF Specification for all the nitty gritty details:

pdf

And "iText in Action" to see how best to apply that information within
iText.
